Bessey TWM28-30-12 Hold Down Clamp 1400 Lb 12 Inch

Product Description

The BESSEY TWM28-30-12 is a manual hold down clamp designed for workholding applications where consistent clamping pressure and secure fixturing are required. It delivers 1,400 lb of clamping pressure and 1,400 lb of holding capacity, making it a reliable choice for production, fabrication, and machining setups. The clamp mounts via a 28mm stud and is constructed from steel throughout. With a 12-inch maximum opening capacity and a 15-3/4-inch clamp height, it handles a wide range of workpiece thicknesses. Licensed machinists, toolmakers, and fixture builders are the typical installers of this style of clamp.

The TWM28-30-12 is suited for use on machine tables, jigs, and fixture plates in light manufacturing, metal fabrication, and woodworking environments. Its manual operation makes it appropriate for low-cycle or setup-intensive work where pneumatic or hydraulic actuation is not required. The 28mm stud mount is compatible with standard T-slot and stud-mount fixture systems commonly found in production shops. The 4-3/4-inch throat depth accommodates workpieces with moderate edge setbacks from the mounting point.

Installation Notes

Installation is performed by machinists or fixture builders familiar with workholding equipment.

Inspect the clamp body and stud threads for wear or damage before each use.
