How are Hollo bolt connections installed in steel?

How are Hollo bolt connections installed in steel?

The ‘blind connection’ technique requires installation access to only one side of the steel section for exceptional convenience. In comparison to alternative methods such as welding, a Hollo-Bolt connection can be quickly installed by simply inserting the fastener into pre-drilled holes and tightening with a torque wrench.

How does a Hollo bolt hook up to a fixture?

A typical connection is made by inserting the Hollo-Bolt into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve against the hollow section’s inner wall.

How much clamping force does Hollo bolt HCF have?
