Purchase Anchors

The Trubolt wedge anchors, a brand name of wedge anchor, are manufactured by ITW.  They can be purchased online from Concrete Fasteners, Inc. either using the Trubolt name or  the generic term of wedge anchor.  

Description:
Trubolt wedge anchors come with a stainless steel expansion clip permanently fixed to the body of the anchor.   The anchor bodies are available in various types of steels as well as in plating and coatings, zinc plated, hot dipped galvanized, 304 stainless steel and 316 stainless steel.

Testing:
Trubolt wedge anchors have ben tested to ACI 355.2 and ICC-ES Ac193.

Listings:
The Trubolt wedge anchors have been listed as required by local building codes, and include the following agencies;
                
                City of Los Angeles .
                Underwriters Laboratory
                Factory Mutual 
                California State Fire Marshal 
                Caltrans   
                ICC-ES

Advantages:
Trubolt wedge anchors are compliant with the 2006 International building codes (IBC).  There is a 360-degree expansion of the expansion clip for reliable and consistent holding values in solid concrete.  The non-bottom bearing Trubolt can be placed in a hole deeper than the anchor penetration in the concrete.  The diameter of the anchor is the same diameter as the hole that needs to be drilled into the concrete.   The Trubolt is designed to be inserted through the hole in the fixture that is being attached to the concrete, thus eliminating hole spotting.  Each Trubolt is inspected for embedment depth once it is installed in the concrete in order to  allow for inspection of proper installation.

Sizes
The first number in the description of a Trubolt is the diameter of the anchor and the second number is the length of the anchor.  Since the Trubolt is what is called a fully threaded wedge anchor, it is important to be aware that the thread length below minimum embedment requirements and the anchor can be installed improperly without ensuring that the minimum embedment for each diameter is met.  Each diameter and length of Trubolts have a maximum thickness of material to be fastened.
