These anchors are made of rustproof zinc alloy and designed for use with a lag screw. The screw length should equal the sum of the thickness of the item to be fastened, the length of the anchor, and another 1/4” in order for the tip to protrude from the bottom of the shield after expansion. A shorter lag shield is recommended in harder concrete to minimize drilling time. For softer masonry, long shields offer optimum holding power.
