GB/T 3632 Sets Of Torshear Type High Strength Bolt Hexagon Nut And Plain Washer For
Steel Structures

Tension Control Bolts, TC Bolts or Twist Off Bolts are now the most popular choice in high-strength
structural bolting and formally recognized by the AISC (American Institute of Steel Construction) and
the RCSC (Research Council on Structural Connections) as an approved installation method.

A Tension Control Bolts consists of 1 bolt, 1 nut and 1 washer, pre-assembled and there for they are
shown, 1 lot number, on the certification paperwork. Tension Control Bolts assemblies come with their
own built in tension control device (spline) to ensure dependable and repeatable tension levels are
achieved with each installation. They are installed with a specialized electric shear wrench that has an
outer socket that turns the nut counterclockwise, while grabbing the spline with the inner socket turning
it clockwise. When the proper tension level has been achieved the spline snaps off giving you a visual
indication of proper installation.

TC Bolts use a proprietary lubrication on the nut, to control the clamping force of the bolt and ensure
the appropriate tension level is achieved. Because of this proprietary lubrication, it is NOT permissible
to re-lubricated TC bolts, in the field, only the manufacture of a TC bolt can re-lubricate a TC assembly.

Tension Control Bolts and the innovative Shear Wrench system are the lowest cost method for installing
preloaded or High Strength Friction Grip bolts.


QBH TC Bolts as they are commonly known throughout the world, are replacing conventional
high strength friction grip bolts and swaged collar rivets simply because they are quick and
easy to install using lightweight electric shear wrenches. 
Guaranteed tension together with
visual inspection removes the likelihood of operator error and ensures engineers that connections
are tightened in accordance with specifications.


Our System HRC structural bolting assemblies are used in a wide range of applications, from bridge
splice plates to beam-to-column connections, from stadia roof trusses to rail switches and crossings. 

The combination of a TC bolts superior tensile strength and phenomenal ductility result in a truly
universal bolt that can be employed in almost all steelwork connections.



Tension Control Bolt Advantages:

  1. Proper tension ensured
  2. Dependable & Repeatable results
  3. Can be used in shear or in tension
  4. One man installation on one side of the structure
  5. Light weight electric wrench can install multiple diameters
  6. Quick & easy installation, no match marking required
  7. Reduced job site noise
