To use lag anchors, specifically lag shield concrete anchors as described in the provided reference, you place the material you want to fasten over the anchor's location, insert the lag screw through the material and into the anchor, and then tighten the screw to expand the anchor and secure the material.
Lag anchors are a common type of fastener used to secure objects to solid base materials like concrete, brick, or block. While there are different types, a common method involves using a lag screw in conjunction with an expanding anchor shield. The process is designed to create a strong, secure hold by wedging the anchor firmly against the sides of the drilled hole as the screw is tightened.
Based on the process described in the reference regarding lag shield concrete anchors:
- Position the Fixture: Align the material or fixture you are fastening so that the hole in the fixture is directly over the anchor's location in the base material. (The anchor is typically installed into a pre-drilled hole in the base material before this step).
- Insert the Screw: Pass the lag screw through the hole in your fixture. Then, insert the tip of the lag screw into the opening of the anchor shield that is in the base material.
- Tighten and Expand: Use an appropriate wrench to turn the head of the lag screw. As you tighten the screw, it is driven deeper into the anchor shield, causing the shield to expand outwards. This expansion creates pressure against the walls of the drilled hole in the concrete or masonry, firmly locking the anchor shield and the screw in place, thereby securing your fixture.
The final result is a strong mechanical connection that holds the fastened material tightly against the base surface. Proper hole size and anchor type for the specific base material are crucial for effective use.
