Bar Clamp Bessey GZ 120/60 mm steel screw clamp for workshop clamping 120 mm throat 60 mm opening

Bessey GZ 120/60 mm steel screw bar clamp is a workshop clamp developed for controlled, steady holding of workpieces during assembly, welding, gluing and machining. The tool features a 120 mm throat depth that allows access into moderate recesses and a screw-actuated jaw that opens up to 60 mm to accommodate a range of material thicknesses. Constructed of steel, the clamp is intended for repeated use in metalworking and general workshop applications where reliable pressure and positional stability are required.

Advantages

The screw mechanism provides precise control of clamping pressure and fine adjustment, reducing the risk of slipping or movement during work. Steel construction ensures durability and resistance to deformation under load, while the compact design and moderate throat depth make the clamp versatile for common workshop tasks. The jaw profile and screw feed offer stable contact with flat or slightly irregular surfaces, improving alignment for welding, bonding and machining operations.

Suitable for

• Holding metal parts during welding and fabrication
• Clamping components for gluing and assembly
• Securing workpieces for drilling, milling and light machining
• Temporary fixturing in small-to-medium workshop setups

Key specifications

• Throat depth: 120 mm
• Maximum jaw opening: 60 mm
• Material: steel construction for frame and screw
• Operation: screw-actuated clamping for precise pressure control
• Design: bar clamp format suitable for one-handed positioning and tightening

How to use

Position the clamp so the fixed jaw rests against one side of the workpiece and the movable jaw aligns with the opposite side. Rotate the screw handle to advance the movable jaw until it contacts the material, then tighten gradually to achieve the required clamping pressure without over-torquing. For welding or machining, confirm the clamp is securely seated and that the throat depth provides proper access to the work area. Release by rotating the screw in the opposite direction until the jaws open sufficiently to remove the workpiece.

Usage recommendations

Use the clamp within its 60 mm opening and 120 mm throat limits; avoid applying impact loads or using the clamp as a pry tool. Inspect the screw and jaw surfaces periodically for wear or deformation, and keep threads clean and lightly lubricated to maintain smooth operation and consistent clamping force.
