Welding Table Clamp 8 in Jaw
The Bessey TW16-20-10K is a welding table clamp built for fabricators who need a secure hold on workpieces during welding, assembly or inspection. Its 8 in maximum jaw opening and 4 in fixed throat depth suit medium-sized parts on tables drilled for 5/8 in holes. A sliding arm on a tempered profile allows quick positioning before the Acme-thread spindle applies clamping force.
Installation and Common Issues
The clamp drops into any standard 5/8 in table hole and locks with the included T-bar handle, so no tools are required for mounting or removal. Because the throat depth is fixed at 4 in, the clamp cannot reach past tall flanges or deep recesses; users should verify reach before starting a job. Debris in the Acme threads can reduce holding power, so keeping the spindle clean is the main maintenance step.
Sustained Load Behaviour
Under continuous load the tempered profile and Acme spindle maintain the rated 650 lb holding capacity without the relaxation sometimes seen in lighter clamps. The fixed throat eliminates pivot play, keeping the workpiece stationary during long weld sequences or when the table is bumped. Heat from nearby welding does not affect the mechanical lock, so the clamp remains reliable throughout extended sessions.

Questions about this item
How can I verify the clamp is holding correctly after mounting it in a 5/8 in table hole?
Tighten the ACME-thread spindle until the sliding arm locks against the workpiece; the tempered profile should show no flex at the rated 650 lb holding capacity.
What components come with the TW16-20-10K and what must I supply separately?
The clamp includes the fixed 4 in throat, 8 in jaw opening, sliding arm, tempered profile and a T-bar; you must provide a welding table with 5/8 in holes.
Which capacity version of this Bessey table clamp should I choose for heavy steel fabrication?
This model delivers a single 650 lb holding capacity with an 8 in jaw opening and 4 in throat depth, suited for heavy steel work.
