You must consider numerous technical specifications when using Lag Shield Anchors. This includes diameter, internal thread length, minimum embedment and required hole size. The Lag Shield Anchor is a great fastener when very hard (short) concrete or lower grade (long) concrete is a concern. The size of the anchor refers to the diameter of the lag bolt used with this fastener. Once you have determined all these factors, you can find the expected holding values in the technical information below.


To determine the length required, add the thickness of the material you are fastening, plus the lag shield anchor length, plus an additional half an inch. NOTE: The tip of the screw must protrude from the bottom of the lag shield anchor to ensure proper expansion.


The forces on a Lag Shield Anchor transfer to the material in which installation occurs. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power. As a rule of thumb, the expansion anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact is part of the load conditions, you should increase the spacing.
