Acoustic Lag Anchors

Also Called: Acoustic Lag Bolts, Acoustic Lag Screws, Flat Hanger Screws, Spade Lag Screws

Acoustic Lag Anchors have sharp points, wood screw threads and a hole on the flat end. They can be driven with a driver tool, or installed using an adjustable wrench or pliers. They are ideal for tie-down and tie-wire applications. Commonly found in suspended ceiling installations, they can also be used for wire guiding and hanging pipe, fixtures and more.

Anchor Bolts

Anchor Bolts are designed for structural anchoring applications. For a right-angle hook, select "L" style; "J" style has a circular hook. For outdoor use, choose hot-dipped galvanized due to superior corrosion properties. A nut and washer are included where noted.

Caulk-In Anchors

Also Called: Calk-In Anchors, Expansion Caulk-In Anchors, Machine Bolt Anchors, Machine Screw Anchors

Expansion Caulk-In Anchors consist of a pre-assembled internally machine screw threaded expander cone and lead alloy caulking sleeve. Use in concrete, block, brick and stone. A setting tool (required) matched to the anchor size pushes the caulking sleeve into the hole as the expander cone causes it to expand and fill the hole. Use with cap screws and other machine screw threaded fasteners. Caulk-In Anchors require a larger hole than comparably sized Drop-In Anchors but are available for smaller screw diameters and, because of their short length, are ideal for shallow holes. Do not use this anchor in overhead applications.

Drive Pins (Masonry)

Also Called: Hammer Drive Pins

Designed for light duty, static load applications where holding strength is not an important factor, Drive Pins permanently attach fixtures to concrete and certain types of concrete block. They are installed using a standard hand tool (do not use a powder actuated tool with these pins). A steel washer near the point retains the pin in the installation tool and guides it during the driving operation. Do not use overhead.

Drive Rivets (Masonry)

Also Called: Masonry Drive Pins, Masonry Pin Grip Drive Rivets, Masonry Rivets

These tamper resistant Masonry Pin Grip Drive Rivets fasten into masonry and brick blocks without special installation tools. Driving the pin flush with the rivet head causes prongs to expand inside the masonry producing a strong riveted joint.

Drop-In Anchors

Also Called: Red Head Multi-Set Drop-In Anchors, Multipurpose Expansion Anchors

Designed for anchoring in concrete, Drop-In Anchors are internally machine screw threaded and have an expansion cone insert. A setting tool (required) sized to match the anchor drives the cone to expand the anchor inside the hole. Anchors with lips mount flush with the material's surface; if below the surface setting is desired, select an anchor without a lip. Use with cap screws, threaded rod, and other machine screw threaded fasteners. These shell type anchors can be used for overhead anchoring.

Expansion Shields, Lag

Also Called: Lag Expansion Shields, Lag Screw Anchors, Lag Screw Shields, Lag Shields

Lag Expansion Shields are designed for concrete and the mortar joints of block and brick. Since they are not internally threaded, use lag screws (which are sometimes called lag bolts). Use the Short style in harder masonry to reduce drilling time; the Long style develops better strength in soft or weak masonry.

Expansion Shields, Machine Bolt Double

Also Called: Double Machine Bolt Anchors, Two-Way Expansion Anchors

Using a dual expansion system, Machine Bolt Double Expansion Shields are well suited for solid concrete, block, brick and stone. They are internally machine screw threaded and expand as you tighten the screw or bolt (not supplied). Do not use in overhead applications.

Expansion Shields, Machine Bolt Single

Also Called: Machine Bolt Anchor, Single Expansion Anchors

Designed for concrete, block, brick and stone, the Machine Bolt Single Expansion Shield consists of an internally machine screw threaded expander cone and a set of expansion shields. Tightening the screw (not supplied) causes the wedge shaped cone to expand the shields inside the hole. Use with cap screws and other machine screw threaded fasteners. Not for use in overhead applications.

Hollow Wall Anchors, Drill and Drive Style

Also Called: Hollow Wall Anchors, Mollies, Molly Anchors, Molly Bolts, Wall Grip Anchors; also, Drive Hollow Wall Anchors, Drive Anchors

Offering better holding power than nails and screws, these sleeve type anchors are commonly used to mount fixtures to hollow walls like drywall (wallboard) and wood paneling. Prongs under the flange pierce the mounting surface to prevent anchor rotation as its screw (supplied) is tightened. Meanwhile, inside the wall, metal strips flare to lock the anchor in place. The screw may be removed and replaced without affecting the anchor. Hollow Wall Anchors are available in two styles: Drill Style requires a pre-drilled hole and Drive Style makes its own hole as it is driven into drywall.

Hollow Wall Anchors, Sanko

Also Called: T Anchors, Stud Toggle Anchor

These "T" style Sanko Hollow Wall Anchors are gravity operated. Position the retaining "T" bar toggle head to be inline with the anchor stem and insert into a drilled hole in the hollow wall. As you twist the anchor stem, gravity causes the retaining bar to rotate and secure the anchor. The hole size required for "T" style anchors is smaller than similarly sized toggle bolts.

Lead Anchors, Wood Screw

Also Called: Screw Anchors, Lead Expansion Anchors, Wood Screw Anchor

Used in concrete, block and brick, Wood Screw Lead Anchors are intended for light duty applications. The anchor expands when a wood or sheet metal screw (not included) is installed. Do not use for overhead anchoring.

Masonry Screw Anchors

Also Called: Tapcon Masonry Screws, Concrete Screws

Fasten into concrete, brick and hollow block using Masonry Screw Anchors. This masonry anchor cuts its own threads in a pre-drilled pilot hole. No inserts are needed, making installation fast, and the screw anchors can be removed. Use as a replacement for plugs and small diameter expansion anchors. Available in Slotted Hex Washer and Phillips Flat heads.

Nail-In Anchors

Also Called: Hammer Drive Anchors, Drive Nail Anchors, Nail-Ins

These light duty, tamper resistant anchors are used for permanent mounting in concrete, block, brick and stone. Drive the center pin flush to expand the body and lock it in place. Do not use Hammer Drive Nail-In Anchors for overhead applications.

Plastic Plug Screw Anchors

Also Called: Plastic Plugs, Fluted Plastic Anchors

Designed for concrete, block, brick and stone, these light duty Plastic Plug Screw Anchors are used with sheet metal and wood screws (not supplied). The anchor expands when the screw is installed. Not for overhead usage.

Plastic Screw Anchors

Also Called: Conical Anchors, Plastic Anchors

For lightweight anchoring in concrete, hollow block and brick, solid brick and wallboard applications. Fins on the cone shaped body prevent Plastic Screw Anchors from turning when the wood or sheet metal screw (not supplied) is installed.

Plug Anchors, Rawl

Also Called: Rawl Screw Plug Anchors

The Rawl Screw Plug Anchor is designed to be used in concrete, block, brick and stone, and can be used with wood, sheet metal, and lag screws. It consists of braided jute fiber with an internal lead core lining. To prevent damage to the anchor and screw, the unthreaded shoulders of wood and lag screws should not enter the plug.

Ribbed Plastic Anchors

Also Called: Plug Anchors, Polysets

These light duty Ribbed Plastic Anchors are used in concrete, hollow block and brick, solid brick and wallboard applications. The anchor expands to grip the wall as you tighten the wood or sheet metal screw (not included).

Sleeve Anchors

Also Called: Bolt Anchors, One Step Anchors

Sleeve Anchors, which includes Acorn and Hex Nut, Flat and Round Head styles, are used in concrete and masonry applications. A pre-drilled hole is required, which should be the same size as the anchor diameter. As the nut or screw is tightened, an internal expander causes the expansion sleeve to expand gripping the hole tightly. They are pre-assembled and rated for heavy loading.

Solid/Hollow Wall Anchors, Toggler

Also Called: Toggler Alligator Solid/Hollow Wall Nylon Anchors

Toggler brand Alligator Solid/Hollow Wall Nylon Anchors are general purpose anchors that can be used in most materials including concrete, wood, plaster, masonry, stone, ceramic tile, stucco and drywall. A lag, wood or sheet metal screw (not supplied) expands and compresses the anchor causing it to conform to the inner surface of the hole.

Stud Anchors, Chemical

Also Called: Chemical Capsule Anchor and Chisel Stud Assembly

Chemical Capsules are used with Chisel Stud Assemblies. Inside the capsule is a "synthetic mortar" that bonds the machine screw threaded stud to the concrete. Useable in lightweight and soft masonry substrates, chemical bonding resists loosening from shock and vibration. Also, no stress is created unlike anchors that require setting or other forms of expansion.

Stud Anchors, Red Head

Also Called: Red Head Stud Anchor, Stud Bolt Anchors

Red Head Stud Anchors are pre-assembled and consist of a bolt body and an expander end plug. Designed for concrete anchoring, they require a pre-drilled hole the same diameter as the anchor. Hammer driving the anchor causes the expander plug to expand the anchor, thus eliminating torquing requirements. This bottom load bearing design is useful in leveling and jacking applications.

Toggle Bolt Anchors, Toggler

Also Called: Toggler Toggle Bolt Anchors, Never-Drop Toggle Anchors, Strap Toggle

Toggler brand Toggle Bolt Anchors are similar to toggle bolts and can be used in most hollow walls, ceilings and floors including: hollow brick; hollow, cinder and concrete block; cement and gypsum board; drywall; plaster; and paneling. Installed without a screw, the wall is clamped between the wing (inside the wall) and a cap (outside the wall) connected by straps, so you won't lose the wing inside the wall when you install or remove the screw. Requiring a hole size smaller than comparable toggle bolts, they are ideal for heavy loads.

Toggle Bolts

Also Called: Spring Toggles

Toggle Bolts are used in hollow wall applications like drywall and concrete block, and are two-piece assemblies that consist of a machine screw and a spring wing toggle. To install, the wings are folded toward the screw head and inserted through a pre-drilled hole. Spring action causes the wings to open inside the wall, once clear of the entrance hole. Removing the screw will cause the toggle wing to fall inside the wall. (Spring toggle wings are sold separately.) Toggle Bolt sizes refer to the screw supplied--common diameters are 1/8 (which is a 6-32 machine screw), 3/16 (a 10-24 machine screw), 1/4-20, 5/16-18, 3/8-16 and 1/2-13. The screw must be long enough to allow the wings to open after passing through the fixture and the wall.

Toggle Wings, Spring (no screw)

Also Called: Toggle Wings

These are the same Spring Toggle Wings that are supplied with the flat, mushroom and round head toggle bolts. Use these if yours are hopelessly lost in the wall, or if you want to select a screw different from those normally supplied. Toggle bolts are hollow wall anchors (see Toggle Bolt listing).

Toggles, Poly, Rawl

Also Called: Rawl Poly Toggles, Plastic Toggles, Toggle Anchors

The Rawl Poly Toggle is a plastic anchor designed for paneling, wallboard and solid masonry that is screw actuated (screw not supplied). Break off the outer wings when installing in solid base materials.

Wallboard Anchors, One Step

Also Called: E-Z Ancor Self-Drilling Drywall Anchors, EZ Anchors

These one step, one piece, self drilling anchors are designed for 3/8", 1/2" and 5/8" gypsum wallboard. Available in metal and nylon versions, the tri-cut point drills a small hole, then the anchor screws into the wallboard until it is flush. Drive the anchor with a #2 Phillips bit. Use sheet metal screws (not supplied) to mount fixtures. E-Z Ancor Self-Drilling Drywall Anchors are removable.

Wedge Anchors, Red Head

Also Called: Red Head Wedge Anchors

Available in machine screw threaded stud diameters ranging from 1/4" to 1 1/4", these heavy duty Red Head Wedge Anchors are designed for concrete applications. The diameter of the anchor is the hole size required. Because the anchor is not bottom bearing, it can be used in hole depths greater than its length. Expand the anchor by tightening the nut.

Wedge Anchors, wej-it

Also Called: wej-it Wedge Anchors

wej-it Wedge Anchors are fully assembled concrete anchors that require a pre-drilled hole of the same diameter as the anchor. An exclusive feature minimizes vibration-induced wedge loosening.
