This Heavy Duty G-clamp, 76 mm, is a manual clamping tool used to hold workpieces together or to secure components to a bench while you saw, file, glue, drill or weld. The 76 mm figure refers to the maximum jaw opening (clearance between screw and frame), giving a compact but robust capacity for light-to-medium workshop tasks where controlled, steady pressure is required.

The clamp is manufactured from drop-forged carbon steel, broadly equivalent to C45 / EN8 grades, and is heat-treated to increase yield strength and wear resistance. The frame is finished in a black powder coat to reduce surface corrosion, while the screw and swivel pressure pad are zinc-plated to improve corrosion resistance and reduce galling. The screw uses a metric coarse thread conforming to ISO metric thread standards (ISO 261/965), and the screw is fitted with a metal T-bar handle for manual drive. The pressure pad is a free‑rotating swivel type to distribute load evenly across the workpiece and reduce marking.

Typical applications include woodworking clamps for gluing and assembly, metalworking holding for light fabrication and tack welding, general workshop fixturing, car bodywork and maintenance tasks where a compact clamp is needed. Industries that commonly use this style of G-clamp include joinery, small-scale fabrication, automotive repair, model and toolmaking, and education or training workshops.

Key benefits of this 76 mm G-clamp are its robust forged-steel construction for sustained clamping cycles, the corrosion-resistant finishes that increase service life in workshop environments, and the ISO-conforming metric screw thread for predictable movement and compatibility with replacement parts. The swivel pad helps protect finished surfaces and improves contact on uneven materials, while the T-bar handle gives good manual leverage for controlled clamping force.

Duchy Fasteners stocks G-clamps across a range of throat capacities and pack options; alongside this 76 mm model we typically carry smaller 25–50 mm and larger 100–200 mm sizes, available singly or in multi-packs to suit workshops and trade users.
