Hold-Down Machine Clamp

This Bessey hold-down machine clamp is built for machine-shop welding and fabrication tasks that demand secure workpiece fixation. Its long-reach design and 7000 lb load limit suit heavy-duty clamping on T-slot hold-down tables. The integrated swivel rocker provides a pivot point for self-alignment during setup. It is not for buyers who need a lighter clamp for delicate assembly work.

7000 lb Load Limit

The single specification that decides suitability is the 7000 lb load limit, which defines the maximum clamping force the tool can safely apply. A maximum torque of 43 lb-ft governs how tightly the clamp can be driven without overload. T-slot compatibility is confirmed for standard hold-down tables. Builders who need higher force capacity must select a different clamp.

Capacity and Headroom

The clamp accommodates a maximum clamping height of 1-1/4 in., giving headroom for moderately thick workpieces or riser blocks. Width measures 1-1/4 in. and length 3-3/4 in., fitting standard T-slot spacing. The 3/8 in. slot size matches common table hardware. Jobs requiring greater reach or taller clearance will exceed this tool's range.

Questions about this item

What does the 7000 lb load limit mean when the clamp is on a T-slot table?

The 7000 lb load limit is the maximum clamping force the hold-down can apply to a workpiece when properly mounted on a T-slot table, assuming the slot and fasteners can handle the same force.

How does the 3/8 in slot size limit the tables this clamp can be used with?

The 3/8 in slot size means the clamp fits only T-slots with a 3/8 in opening; it will not work with larger or smaller T-slot dimensions without an adapter.

What clearance is needed to fit the 3-3/4 in length and 1-1/4 in width into a machine setup?

The clamp body measures 3-3/4 in long by 1-1/4 in wide, so the fixture or table must provide at least that much clear space around the T-slot for installation and swivel movement.
