Lag Screw Shiled Anchor

This two-part expansion shield is preassembled into a self-contained single unit. The shell-like unit has tapered internal threads for a portion of its length. The outside of the anchor has a series of circumferential ribs starting at the bottom and running for a major portion of its length. The back end of the anchor has two equally spaced tibs that protrude beyond its length. Precision internal threads permit easy turning of the lag screw without lubrication. Once fastened, an object may be easily unbolted and removed. All parts of the completed unit are made of zinc alloy commonly known as Zamak3,a rustproof material. The anchor comes in two lengths, short or long. The short lag shield is for anchoring in high grade concrete or where thickness of base material prohibits the use of a longer length shield. The long Lag shield is for use in lower grade base material or where extra anchoring strength is required.
