Wedge Type Anchors —
SPECIFIED FOR ANCHORAGE INTO CONCRETE
tru_prod1b.jpg (9144 bytes)
Trubolt Wedge anchors feature a stainless steel expansion clip, threaded stud body, nut and washer. Anchor bodies are made of plated carbon steel, hot-dipped galvanized carbon steel, type 304 stainless steel or type 316 stainless steel as identified in the drawings or other notations.

Trubolt+ Wedge anchors consist of a high-strength threaded stud body, expansion clip, nut and washer. Anchor bodies are made of plated carbon steel. The expansion clip consists of a split cylindrical ring with undercutting grooves.

The exposed end of the anchor is stamped to identify anchor length. Stampings should be preserved during installation for any subsequent embedment verification.

Use carbide tipped hammer drill bits made in accordance with ANSI B212.15-1994 to install anchors.

Anchors are tested to ASTM E488 criteria and ICC-ES AC193. Anchors are listed by the following agencies as required by the local building code: ICC-ES, UL, FM, City of Los Angeles, California State Fire Marshal and Caltrans.

See Appendix B for Trubolt on performance values in accordance to 2006 IBC.

See Appendix C for Trubolt+ on performance values in accordance to 2006 IBC.

ADVANTAGES

2006 International Building Code (IBC) Compliant

Versatile fully threaded design is standard on sizes up to 3/4" diameter and 10" length

Anchor diameter equals hole diameter

Standard carbon and stainless

360° contact with concrete assures full expansion for reliable working loads

Non bottom-bearing, may be used in hole depth exceeding anchor length

Can be installed through the work fixture, eliminating hole spotting

Inspectable torque values, indicating proper installation

Fully Threaded Advantage
Trubolt’s fully threaded feature eliminates subsurface obstruction problems.
Fully threaded design accommodates various material thicknesses at the same embedment. One anchor length saves time and money.

Installation:

INSTALLATION STEPS

	1. Select a carbide drill bit with a diameter equal to the anchor diameter. Drill hole to any depth excceeding the desired embedment. See chart for minimum recommended embedment.
	2. Clean hole or continue drilling additional depth to accommodate drill fines.
	3. Assemble washer and nut, leaving nut flush with end of anchor to protect threads. Drive anchor through material to be fastened until washer is flush to surface of material.
	4. Expand anchor by tightening nut 3-5 turns past the hand tight position, or to the specified torque requirement.

Combined Tension and Shear Loading — for Trubolt Anchors

Allowable loads for anchors subjected to combined shear and tension forces are determined by the following equation:
(Ps/Pt) ^5/3 + (Vs/Vt)^5/3 < 1

Ps = Applied tension load Vs = Applied shear load Pt = Allowable tension load Vt = Allowable shear load
