Bessey STC-HV20 Toggle Clamp Horizontal 450 Lb U-bar

Product Description

The BESSEY STC-HV20 is a manual hold-down toggle clamp configured for horizontal handle orientation with a straight base and U-bar design. Rated at 450 lb holding capacity, it is built from carbon steel for durability in industrial and fabrication environments. The clamp measures 6.57 inches in overall length and 2.56 inches in overall height, making it a compact but capable workholding solution. A pressure pad cap is included to protect workpiece surfaces during clamping. Machinists, welders, and fixture builders install this type of clamp on jigs, fixtures, and workholding tables where repeatable, fast part securing is required.

The STC-HV20 suits production and job-shop settings where parts must be held securely during machining, welding, assembly, or inspection operations. Its straight base mounts flush to flat fixture plates or workbenches. The horizontal handle orientation keeps the actuation path low-profile, which is useful in multi-clamp fixtures where vertical clearance is limited. The included pressure pad cap accommodates slight surface variation and reduces marring on finished or semi-finished workpieces.

Key Features

• 450 lb holding capacity for secure workholding in production fixtures
• Horizontal handle orientation with straight handle style for low-profile actuation
• U-bar design with included pressure pad cap to protect workpiece surfaces
• Carbon steel construction on both body and handle for rigidity and wear resistance
• Straight base with 0.22-inch diameter mounting holes for direct fixture plate installation
• 1 inch height under bar provides consistent clamping clearance for typical workpiece thicknesses

Compatibility

Designed as an OEM-style replacement or direct-fit addition for standard toggle clamp fixture applications requiring a horizontal, straight-base, U-bar hold-down clamp with a 450 lb capacity rating.

Installation Notes

Install using fasteners sized to the 0.22-inch mounting hole diameter; confirm that the fixture plate material and fastener grade are rated for the intended clamping loads. Verify the height-under-bar dimension of 1 inch clears the workpiece before finalizing base position on the fixture. Torque mounting fasteners to the fixture plate per the fastener manufacturer specification for the base material in use. Inspect pivot pins and the spindle adjustment periodically for wear in high-cycle applications.
