4 Easy Facts About TENSION CONTROL BOLTS LIMITED - Officers (free Shown

Tension control bolts,  TC Bolts  or Twist Off Bolts, have turned into one of the world's most commonly utilized approach to stress high strength structural bolts, as they can be utilized in nearly all steelwork connections. As a high strength stress control bolt supplier, AFT provides ASTM A325 and A490 TC bolts in bolt sizes varying from 5/8" as much as 1" and lengths from 1-1/2" approximately 7".

Tension Control Bolts: Properties, Benefits & Common Problems

Please contract us today with any questions on TC bolts or to ask for a quote on big amounts. We're here to assist! TC bolts include a three-piece fastening system with 1) a round head bolt with a truncated, flat area at the top of the bolt, and a 24-sided tip which protrudes from the opposite end.

2) a heavy hex nut and, 3) a structural flat washer. Tension Control Bolt Resources:.

A stress control bolt is a pre-assembled bolt, nut, and washer used particularly in steel frame building. Also known as a TC bolt, they have a domed head instead of a hex head due to the fact that they are set up from a spline on their other end. This spline gets in touch with an unique power wrench for installation.

Stress control bolts come perfectly pre-lubricated by the manufacturer. They are ready to be installed with a shear wrench. This wrench has an inner and an outer socket. The inner socket rotates the spline clockwise and the outer socket turns the nut counterclockwise. As soon as the correct tension has actually been achieved, the spline breaks off.

There is just one lot number associated with the stress control bolt assembly and they come exactly oiled. They are regulated by the AISC, American Institute of Steel Building And Construction, and RCSC, Research Council on Structural Connections. The single most unique feature of the tension control bolt is that it is set up with an exactly calibrated shear wrench that takes the guesswork out of achieving the correct preload (stress developed in a fastener when it is tightened).

Many feel that stress control bolts are more affordable due to the fact that they require just one person for their setup and evaluation. For that reason, installation goes faster and with less mistakes. Stress control bolts must comply with specs noted by the RCSC, as pointed out prior to and any destruction of the lube on the bolt will trigger it to stop working evaluation.
