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

Tension Control Bolts, TC Bolts or Twist Off Bolts are now the most popular choice in high-strengthstructural bolting and formally recognized by the AISC (American Institute of Steel Construction) andthe 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 areshown, 1 lot number, on the certification paperwork. Tension Control Bolts assemblies come with theirown built in tension control device (spline) to ensure dependable and repeatable tension levels areachieved with each installation. They are installed with a specialized electric shear wrench that has anouter socket that turns the nut counterclockwise, while grabbing the spline with the inner socket turningit clockwise. When the proper tension level has been achieved the spline snaps off giving you a visualindication of proper installation.

TC Bolts use a proprietary lubrication on the nut, to control the clamping force of the bolt and ensurethe appropriate tension level is achieved. Because of this proprietary lubrication, it is NOT permissibleto 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 installingpreloaded or High Strength Friction Grip bolts.QBH TC Bolts as they are commonly known throughout the world, are replacing conventionalhigh strength friction grip bolts and swaged collar rivets simply because they are quick andeasy to install using lightweight electric shear wrenches. Guaranteed tension together withvisual inspection removes the likelihood of operator error and ensures engineers that connectionsare tightened in accordance with specifications.Our System HRC structural bolting assemblies are used in a wide range of applications, from bridgesplice 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 trulyuniversal 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
