Bessey STC-HH70 Toggle Clamp Horizontal 700 Lb U-bar

Product Description

The BESSEY STC-HH70 is a manual hold-down toggle clamp configured in a horizontal handle orientation with a U-bar and flanged base. It delivers a 700 lb holding capacity and is built from steel throughout, including the handle. This clamp is designed to secure workpieces firmly against a fixture or jig surface, making it a standard tool in welding, woodworking, machining, and fabrication setups. The flanged base provides a stable, eight-hole mounting pattern for rigid attachment to work surfaces. The open bar end and 1.54 inch clearance height under the bar accommodate a range of workpiece thicknesses without modification.

The STC-HH70 is suited for production jigs, welding fixtures, and assembly tables where consistent, repeatable clamping force is required. Its horizontal handle keeps the actuation path low-profile, making it practical in tight fixture layouts. The straight handle with red and black coloring provides a clear visual indicator of clamp state. This clamp is typically installed by tool and die makers, fabricators, machinists, and fixture builders in both light industrial and shop environments.

Compatibility

Designed as an OEM-style replacement or direct-install toggle clamp for horizontal hold-down applications in welding fixtures, machining jigs, and fabrication assembly tables requiring a flanged base mount.

Installation Notes

Installation is typically performed by machinists or fabricators using standard drill and fastener tooling to secure the flanged base through the eight provided mounting hole positions. Ensure the mounting surface is flat and rigid to maintain consistent clamping force and prevent base flex under load. Verify workpiece height falls within the available clearance under the bar before finalizing fixture layout. Do not exceed the rated 700 lb holding capacity.
