Bessey STC-S-MFT Horizontal Toggle Clamp Set with Auto-Adjust, 2500 N Holding Capacity, Galvanized Steel, 2-Piece

Unlike fixed-jaw clamps that demand shims and guesswork, the Bessey STC-S-MFT set brings self-adjusting clamping to fixture building and light fabrication. Each clamp in this pair automatically adapts to workpiece thicknesses up to 35 mm, so you can switch between parts without re-adjusting the spindle. The toggle mechanism delivers a holding force of 2500 N, locking workpieces firmly against vibration and tool pressure.

Highlights

• Automatic jaw adjustment up to 35 mm for rapid workpiece changes
• High holding capacity of 2500 N (approx. 250 kg)
• Flanged base with two M6 mounting holes for secure bench or jig attachment
• Galvanized steel body resists corrosion in workshop environments
• Oil-resistant two-component plastic handle provides a comfortable, non-slip grip
• Set includes two clamps, two pressure plates, and two mounting screws

In daily use

Mount the clamps to your welding table, drill press, or assembly fixture using the included screws. The 60° handle opening and 90° clamping arm opening give you clear access for loading and unloading parts. The M8 spindle with 40 mm length allows fine tension adjustment when needed, while the auto-adjust feature handles most variations automatically. Whether you are holding sheet metal for tack welding or securing a jig for repetitive drilling, the toggle action provides a quick, positive lock with minimal effort.
