Bessey TWV16-20-15K Welding Table Clamp

The Bessey TWV16-20-15K is a steel welding table clamp designed for metal fabrication and assembly tasks. It fits tables with a 5/8 in hole and provides a secure hold for workpieces during welding processes. The clamp includes a T-bar for added leverage and features a sliding arm with a tempered profile for durability. It suits welders needing reliable fixturing on compatible tables.

8 in Maximum Jaw Opening

The single specification that determines fit is the maximum jaw opening of 8 in. This capacity defines the thickest workpiece the clamp can accommodate. The throat depth is 1 1/4 in, setting the reach from the table edge. Verify both dimensions against your material thickness and table layout before purchase. The clamp uses an ACME standard thread mechanism.

Sustained 550 lb Holding Capacity

Under continuous load the clamp maintains a holding capacity of 550 lb. This rating reflects steady clamping force during extended weld cycles rather than a momentary peak. The tempered profile sliding arm and steel construction resist deformation when force is applied over time. The 0.6 in outside diameter and 1.2 in overall depth contribute to rigid performance under sustained pressure.

Questions about this item

How does the 550 lb holding capacity translate when the clamp is actually mounted on a welding table?

The 550 lb rating is the maximum force the clamp can apply when properly seated in a 5/8 in table hole with the sliding arm and tempered profile engaged.

What does the ACME standard mean for the screw mechanism and thread engagement?

ACME threads provide a trapezoidal profile that resists stripping under heavy clamping loads and allows smoother adjustment through the 8 in jaw opening range.

What table hole size and physical clearance does the 0.6 in outside diameter require for installation?

The clamp fits a 5/8 in table hole; the 0.6 in outside diameter and 1.2 in overall depth determine the minimum hole clearance and mounting thickness needed.
