Bessey STC-HH50 Toggle Clamp Horizontal 700 Lb U-bar

Product Description

The BESSEY STC-HH50 is a manual hold-down toggle clamp with a horizontal handle orientation and a U-Bar design, built for securing workpieces in fabrication, welding, woodworking, and fixture-building applications. Rated at 700 pounds holding capacity, it features a flanged base with 8 mounting holes for rigid, low-profile installation. The clamp body and handle are constructed from steel, with a straight red and black handle for positive grip and quick actuation. A spindle is included for adjustable clamping height. Overall length is 8.35 inches and overall height is 1.79 inches, making it a compact, high-force option for benchtop jigs and production fixtures.

The STC-HH50 suits production environments and job-shop fixtures where consistent, repeatable workpiece hold-down is required. The horizontal bar orientation keeps the profile low, which is useful when clearance above the workpiece is limited. The open bar end allows the clamp to swing clear without obstruction. The flanged base mounts directly to steel or wooden fixture plates. It is typically installed by machinists, welders, woodworkers, and tool-and-die technicians on manual assembly lines, drill press tables, and welding positioners.

Key Features

• 700 pound holding capacity for high-force workpiece securing
• Horizontal handle orientation with straight steel handle in red and black
• U-Bar with open end allows unobstructed bar swing
• Flanged base with 8 mounting holes for stable, multi-point fixture attachment
• Spindle included for adjustable clamping height under bar
• All-steel construction for durability in fabrication and production environments

Compatibility

Designed as a direct-mount toggle clamp for standard steel and wood fixture plates in manual assembly, welding, and machining applications where a horizontal hold-down clamp with a flanged base is specified.

Installation Notes

Installation is performed by machinists, welders, or fixture builders using standard hand tools. Mount the flanged base to a rigid fixture plate using all available mounting holes to prevent rocking under load. Verify the height under the bar clears the workpiece correctly before tightening the spindle lock. De-energize or fully stop any machinery before repositioning or adjusting the clamp in a live fixture.
