Precision Welding Table Clamp
The Bessey Tools TWV28-30-17K is a steel table clamp built for welding tables with a 1 1/8 in hole pattern. It provides a 5500 lb holding capacity and a maximum jaw opening of 12 in for securing heavy workpieces. The sliding arm allows variable throat depth to suit different fixturing needs. A T-bar is included for leverage during tightening.
Rigid Steel Construction Handles Heat
The tempered steel profile resists distortion under welding heat and clamping force. No moving hydraulic parts mean there is no fluid to leak or pump to maintain. The 1.1 in outside diameter shank fits standard precision table holes cleanly. Operation stays consistent across repeated cycles without pressure drop.
Sliding Arm And T-Bar Extend Utility
The sliding arm adjusts throat depth up to 1 5/8 in without changing clamps. The included T-bar gives mechanical advantage for reaching the rated 5500 lb capacity by hand. Precision 5/8 in holes on a 2 in grid let you position the clamp exactly where the joint demands.
Accessory Ready For Fixturing
The clamp works with standard welding table accessories that share the 1 1/8 in thread size. Steel construction withstands spatter and grinding debris without damage. The 2.6 in width keeps the footprint narrow between adjacent clamps. No proprietary adapters are needed to integrate into existing precision table systems.

Questions about this item
How do I install the Bessey TWV28-30-17K clamp into a welding table and what step is often missed?
Insert the 1.1 in outside diameter shank into a 1 1/8 in table hole; the step often missed is tightening the T-bar handle to lock the sliding arm before applying the 5500 lb clamping force.
What maintenance or replacement will the Bessey TWV28-30-17K clamp need over time?
The tempered steel profile and sliding arm mechanism require periodic cleaning of weld spatter and light lubrication of moving threads to maintain the 100 lb holding capacity and smooth 12 in jaw operation.
What limit appears first when the Bessey TWV28-30-17K clamp is used continuously at high load?
The 1 5/8 in throat depth restricts reach on thicker workpieces before the 5500 lb capacity or 12 in maximum jaw opening becomes a limiting factor during sustained clamping tasks.
