Top Guidelines Of DTI Washers and TC Bolts: Helping Ensure Torque and Tension

A stress control bolt is a pre-assembled bolt, nut, and washer used particularly in steel frame building. Also called a TC bolt, they possess a domed head rather than a hex head because they are installed from a spline on their other end. This spline links with an unique power wrench for setup.

Stress control bolts come perfectly pre-lubricated by the producer. They are all set to be set up with a shear wrench. This wrench has an inner and an outer socket. The inner socket rotates the spline clockwise and the external socket turns the nut counterclockwise. Once the right stress has been accomplished, the spline breaks off.

There is simply one lot number included in the stress control bolt assembly and they come specifically lubed. They are managed by the AISC, American Institute of Steel Building, and RCSC, Research Council on Structural Links. The single most distinct feature of the stress control bolt is that it is set up with an exactly calibrated shear wrench that takes the uncertainty out of attaining the appropriate preload (tension produced in a fastener when it is tightened).

Lots of feel that stress control bolts are more affordable due to the fact that they need only one person for their installation and evaluation. For that reason, setup goes quicker and with fewer errors. Tension control bolts must follow specs listed by the RCSC, as discussed prior to and any destruction of the lubricant on the bolt will trigger it to stop working examination.
