Zamac Lag Screw Shields anchors

 The Lag Shield is a screw style anchor designed for use with lag bolts.

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 ribs that protrude beyond its diameter and run for a portion of 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 Zamak, a rust-proof 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.

1. Using a hammer drill and a carbide-tipped masonry bit, drill a hole of recommended diameter into the base material. The hole depth should be equal to the length of the lag shield anchor plus one half inch (1/2") or more.

2. Clear the hole of all debris.

3. Place the lag shield anchor, ribbed end first, into the hole. Tap the lag shield with a hammer until it is flush with the surface of the base material.

4. Position the fixture to be fastened over the shield in the base material, insert the lag bolt through the fixture and into the shield, and tighten.

NOTE: If the lag screw begins to torque-up or tighten before the head of the lag screw mates up against the object being fastened, the shield should be driven deeper into the hole by hand hammering the head of the lag screw until flush to the object being fastened. Re-tighten the lag screw to complete the expansion of the shield and to secure the material being fastened.
