Heavy Duty T-Bolt Clamps

Murray’s HD T-Bolt Clamps provide leak-proof connections in applications that require increased installation torque and band load. Designed for heavy-duty applications, HD T-Bolt Clamp bolts and self-locking nuts are Zinc plated carbon steel. All other band components are manufactured from 300 series stainless steel with attention to quality craftsmanship to ensure high corrosion resistance.

HD T-Bolt Clamp Properties

Heavy duty T-Bolt Clamps are designed to provide high tensile strength, durability and corrosion resistance. They are made with a rounded band edge to protect soft hose materials.

HD T-Bolt Clamps are available in two styles:

TBA Series: welded band tongue under the bolt
TBB Series: Floating “channel” bridge under the bolt

Our HD T-Bolt Clamps provide considerably heavier duty construction than standard T-Bolt band clamps. The band is wider and thicker while the bolt is longer with a larger diameter. Compare the sizes below:

Standard T-Bolt

Band width – .75 inch
Band thickness – .025 inch
Bolt diameter – .25 inch
Bolt length – 2.75 inches

HD T-Bolt

Band width – .875 inch
Band thickness – .04 inch
Bolt diameter -.3125 inch
Bolt length – 4 inches

The bolts used in our HD T-bolt clamps are bent to allow a better range along with a longer bolt length. Without this bend, the bolt would bottom out on the band.

Material Options for HD T-Bolt Clamp

Heat-treated alloy steel bolts and self-locking nuts are double-plated, clear chromate finished for high corrosion resistance. All other clamp components are 300 series bright-finished stainless steel. Bands are also available in 316 stainless steel by special order. All stainless steel used is made to AISI and other key global standards.
