The ThunderStud® wedge anchor consists of two pieces, permanently pre-assembled into a
single unit. The carbon steel rod is threaded for a portion of its length. The extreme end of the
threaded portion is rounded to protect the threads from damage while the anchor is being driven
into the hole drilled in the concrete. The other end of the rod has a necked down diameter, which
runs for a short distance, at the end of which it tapers outwardly to the full diameter of the rod.
A precision formed universal clip made of carbon steel is permanently assembled around the
necked down diameter to complete the anchor. Each package contains the correct number of
nuts and washers.
Concrete Wedge Anchor - Approvals:
Listed by Underwriters Laboratories (UL), International Conference of Building Officials
(ICBO) carbon steel only, Board of Standards and Appeals (BSA), City of L.A. Meets or
exceeds U.S. Government G.S.A. Specifications FF-S-325 Group 11, Type 4, Class
Concrete Wedge Anchor - Applications:
Medium to heavy duty into concrete.
Concrete Wedge Anchor - Installation:
(1) Drill hole into concrete with a carbide tipped masonry drill bit conforming to ANSI B94,
12-77, the same size as the ThunderStud® wedge anchor. If the fixture being fastened is
in place and being used as a template to locate the ThunderStud® anchor, the mounting
hole in the fixture should afford clearance for the universal wedge clip on the stud. (2)
Clean hole, place the ThunderStud® wedge anchor through the hole in the fixture or
directly into the concrete and hammer it in to the drilled hole until the threads are below
the surface of the fixture/concrete. (3) Turn the nut by hand until the unit is snugged up.
Tighten the nut with a wrench, approximately three or four full turns, to complete the
fastening.
Concrete Wedge Anchor - Anchor Length:
Minimum embedment, plus fixture, plus nut and washer. The ThunderStud® wedge an-
chor requires no maximum hole depth. The depth of the hole in the concrete should be
the length of the wedge anchor minus the thickness of the material being fastened. This
will result in some extra depth to accommodate a minor amount of concrete cutting which
may not be able to be cleaned out of hole.
