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 Bolt Advantages:
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.
