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 | HD T-Bolt |
|---|---|
| Band width – .75 inch | Band width – .875 inch |
| Band thickness – .025 inch | Band thickness – .04 inch |
| Bolt diameter – .25 inch | Bolt diameter -.3125 inch |
| Bolt length – 2.75 inches | 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.
