Concrete Wedge Anchor -Technical Information

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.
