Hex Expansion Anchor Bolts
Hex Sleeve Anchors / Expansion Bolts
Our Hex Expansion Anchor Bolts are heavy-duty sleeve anchors designed for secure fastening into concrete, brick, stone, and masonry. The bolt assembly consists of four components: a hex flange head bolt, a 4-segment split expansion sleeve, a flat washer, and a cone nut. As the bolt is tightened, the cone is drawn into the sleeve causing it to expand and grip the inside of the drilled hole, creating a reliable mechanical anchor with excellent pull-out resistance.
