Slotted Flat Head Sleeve Anchors, Zinc Plated
Also known as:
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.
