G-clamps are amongst the most common types of clamp in the workshop. Workpieces are held securely by two jaws with an adjustable threaded screw in one of them allowing for different-sized items. The Silverline G-Clamp boasts a robust cast-iron frame with a steel threaded bar. It features a tommy bar handle for easy tightening and the swivel shoe allows clamping of irregular-shaped objects. The copper-plated thread prevents weld spatter from sticking and reinforced shoulders provide greater strength. Corrosion-resistant frame finish.
