Slotted Mushroom Head Toggle Bolts, Zinc Plated

Also known as:  

Spring Toggles

Toggle Bolts are used in hollow wall applications like wallboard 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. See our Toggle Bolt Dimensions & Hole Size reference chart.
