The Single Strategy To Use For Tension control bolt - Wikipedia

Tension control bolts, TC Bolts or Twist Off Bolts, have turned into one of the world's most widely utilized technique 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 offers ASTM A325 and A490 TC bolts in bolt sizes ranging from 5/8" approximately 1" and lengths from 1-1/2" up to 7".

Please contract us today with any concerns on TC bolts or to request a quote on large quantities. We're here to assist! TC bolts consist of a three-piece attachment system with 1) a round head bolt with a truncated, flat area at the top of the bolt, and a 24-sided suggestion which protrudes from the opposite end.

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

anti-corrosion security Stress Control Bolts Ltd has its own metal finish plant producing an environmentally friendly anti-corrosion finishing called Greenkote, which is comparable to galvanising, although it is harder using and easily accepts all paint systems. Discover more about Greenkote.

A tension control bolt is a pre-assembled bolt, nut, and washer utilized especially in steel frame building and construction. Also called a TC bolt, they possess a domed head instead of a hex head due to the fact that they are installed from a spline on their other end. This spline gets in touch with an unique power wrench for installation.

Tension control bolts come perfectly pre-lubricated by the manufacturer. They are all set to be installed with a shear wrench. This Website has an inner and an outer socket. The inner socket turns the spline clockwise and the external socket rotates the nut counterclockwise. Once the proper tension has been accomplished, the spline breaks off.

There is just one lot number involved in the tension control bolt assembly and they come precisely lubed. They are managed by the AISC, American Institute of Steel Construction, and RCSC, Research Study Council on Structural Links. The single most special function of the stress control bolt is that it is installed with an exactly calibrated shear wrench that takes the uncertainty out of achieving the correct preload (stress created in a fastener when it is tightened up).
