Q: Why is the lag shield anchor referred to a 1/4", 5/16", 3/8", 1/2", 5/8"
and 3/4"?
A: That dimension refers to the diameter of the bolt or threaded rod that
fits into the lag shield anchor. All female
anchors are described in this way.
-
Q: Why is the hole size so much larger than the anchor size?
A: The hole size matches up with the outside diameter of the anchor. For
example: a 3/8" drop-in anchor, has an internal thread diameter
of 3/8’ the outside diameter of the anchor is 5/8” so the
hole in the concrete needs to match the outside diameter of the anchor
of 5/8”.

Q: Can I put the lag shield anchor into the concrete deeper than the minimum embedment?
A: Yes and the holding values can be slightly better the deeper the embedment
Q: What type of bolt do I use in a lag shield?
A: Lag Screw bolts are the only type that the lag shield will accept.
-
Q: Why are there two lengths of lag shields, they come in a short and long
version?
A: The longer lag shields are used to develop excellent holding values
in softer base material. The short version just allows for shallower holes
to be drilled in harder base material.
Q: What other names are these type of anchors called?
A: Lag shield, lag screw shields, lag screw anchor, sup-r-lags, lag screw
expansion anchor, LSES.
