Rick Brown, structural products technical services manager for Infasco, has authored an online article on the next generation of Tension Control bolts.

Brown said the cost of bolting can be reduced by 50% when using tension control bolts. “I have been a firm believer in the simplicity of this bolting system, after snug tight simply apply the shear wrench and pull the trigger. When correctly tightened the tip shears off and the tool stops. Simple effective and just about anyone can do it,” Brown wrote. “Simple is good, simple is fast, simple is low cost.”

“What this very simple, effective bolting system has been missing has been a good coating system that addresses long term corrosion resistance,” Brown acknowledged. Infasco has developed a system that will provide 1000 hours of corrosion resistance in a thin film coating.

“I remember visiting a jobsite a few years ago and encountered a concern with mech galv bolts. The ironworker could not get the tip of the bolt to fit into the shear wrench socket,” Brown recalled. The thickness of the coating was the issue.

A new Infasco coating system allows for a long period of corrosion resistance and good short term corrosion protection, Brown said.
