Parallel Screw Clamp Bessey PA55, size 3, 60 mm jaw capacity

Bessey PA55 is a parallel screw clamp, size 3, with a 60 mm jaw capacity designed to hold workpieces securely during gluing, assembly and woodworking operations. The clamp delivers parallel clamping action that keeps pressure even across the entire jaw surface, reducing warping and misalignment when joining boards or fixtures. Its compact size and robust build make it suitable for repeated use in hobby and professional workshops where consistent clamping force and alignment are required.

Advantages

The parallel screw mechanism provides uniform pressure distribution across the jaws, improving joint accuracy and reducing material deformation. Construction from durable materials and precise machining ensures repeatable clamping force and long service life. The 60 mm jaw capacity accommodates a variety of workpiece thicknesses typical for edge gluing and small assembly tasks. Its ergonomic screw handle allows controlled tightening and release for accurate positioning.

Suitable for

• Edge gluing of boards and panels
• Assembly and fixture holding during joinery
• Clamping workpieces for planing, sanding or routing
• Holding parts for drilling or dowel insertion

Key specifications

• Clamping type: parallel screw clamp
• Size class: 3
• Jaw capacity: 60 mm
• Parallel jaw action for even pressure distribution
• Ergonomic screw handle for controlled tightening
• Durable metal construction for repeated workshop use

How to use

Position the clamp jaws around the workpiece with the faces aligned to the surfaces to be held. Turn the screw handle clockwise to bring the moving jaw into contact with the workpiece, then tighten gradually until the required clamping pressure is reached, ensuring the jaws remain parallel to avoid misalignment. To release, turn the handle counterclockwise until the jaw clears the workpiece. For best results, check alignment and pressure during glue curing or machining operations and adjust as necessary.

Usage recommendations

Use protective pads or scrap wood between the clamp jaws and finished surfaces to prevent marking. For long glue joints, apply multiple clamps spaced evenly along the joint to maintain consistent pressure and alignment. Inspect the clamp regularly for wear or damage and keep the screw thread clean and lightly lubricated for smooth operation.
