Hillman 1/2 In. x 2-1/2 In. x Bright Zinc & Chromate Wedge Bolt Anchor (25 Ct.)

WedgeBolt anchors are versatile and can be used in a variety of base materials, including brick, block, concrete, and hollow block. Wedge-bolt anchors have specially designed dual threads that engage the base material immediately upon tightening. Unlike traditional wedge or sleeve type anchors, they will not spin in the hole when attempting to tighten. Wedge-bolt anchors are removable and reusable, unlike traditional anchors, and are manufactured from heat-treated, high strength carbon steel that is plated with commercial bright zinc and a supplementary chromate treatment.
