Heavy-Duty Bar Clamp

The Bessey GSM20 is a forged-steel bar clamp built for welding, assembly and general construction work. Its ClassiX Heavy Duty Pad and tempered alloy steel bar deliver a secure grip and maximum rigidity across a range of materials. A cold-drawn, heat-treated steel bar and steel handle add further durability for demanding shop tasks.

Target Users & Limitations

This clamp suits metalworkers and fabricators who need a strong, single-unit clamp with a 4 3/4 in throat depth for larger workpieces. It is not suited for buyers who need multiple clamps for simultaneous glue-ups or for jobs requiring a lighter, one-handed clamping action.

Key Specification

The clamp provides a 7 1/2 in maximum jaw opening paired with a 4 3/4 in throat depth, determining the largest workpiece it can accommodate. This combination of reach and capacity is the primary factor in deciding whether the GSM20 fits the intended application.

Questions about this item

What is the maximum jaw opening of the GSM20 bar clamp?

The Bessey GSM20 bar clamp opens to a maximum of 7 1/2 inches between the jaws.

How do you apply clamping force with the forged steel handle?

Turn the forged steel handle clockwise to advance the sliding jaw; the common mistake is over-tightening past the point where the pad seats firmly.

What part of the GSM20 should be inspected for wear over time?

Check the tempered alloy steel bar and cold drawn heat-treated sliding jaw for bending or thread damage after heavy use.
