INGCO 3" / 75mm Heavy-Duty Cast Iron G-Clamp (Serre-Joint en G / C-Clamp) – Malleable Cast Iron Body, High-Torque T-Shaped Threaded Screw, and Swivel Pad (HGC0103)

Securing metal fabrications, wood joints, or machinery parts during welding, gluing, or drilling with light-weight or low-grade spring clamps leads to surface slipping, uneven pressure, and joint misalignment. Standard clamps often flex or strip their threads under heavy clamping loads. The INGCO HGC0103 3" (75mm) Heavy-Duty G-Clamp (Serre-Joint en G) is a compact, high-strength clamping tool engineered for maximum holding force, rigid structural stability, and reliable pressure retention. Built with a heavy-duty malleable cast iron frame, this G-clamp provides high resistance to bending, twisting, and impact during demanding workshop tasks.

The precision control and clamping torque of this tool rely on its smooth T-shaped threaded drive screw and swivel pressure pad. The thick T-handle enables maximum manual leverage for effortless tightening, while the fine-pitch threads prevent jaw slipping under vibration. Equipped with a self-aligning swivel pad that adapts to uneven or angled workpiece surfaces, the HGC0103 provides welders, carpenters, machinists, and DIYers with an essential, long-lasting holding solution.

Key Features

• 3" (75mm) Jaw Opening Capacity – Compact 75mm capacity ideal for holding timber pieces, steel plates, and assembly joints.

• Malleable Cast Iron Frame – Heavy-duty cast iron body delivers exceptional strength and flex resistance under high clamping force.

• High-Torque T-Shaped Thread – Precision-machined T-bar screw provides smooth thread action and optimal manual tightening leverage.
