5/16" X 1-1/4" Short Lag Screw Shield Anchors | Box 100

Embedment: 1-1/4 Hold Weight Concrete 4000 psi: 150 lbs Hold Weight Block C-90: 70 Lbs TPI: 18; Drill Size: 1/2 Materials: Concrete, masonry, mortar joint, and brick. Lag shields are used for light to medium duty applications. 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.
