The DongCheng HD071005 5-Inch (125mm) G-Clamp provides heavy clamping power and extra jaw depth for wider material cross-sections. Built with a thick-walled malleable cast iron frame, this clamp resists high bending loads during heavy timber assembly, structural steel fabrication, and welding alignments.

The precision-cut T-shaped thread spindle guarantees smooth, high-pressure clamping while preventing thread stripping or galling under repeated industrial cycles. Combined with a large floating swivel head and a solid sliding bar handle, it offers reliable hold and long-term durability.

Key Features

• Reinforced Malleable Cast Iron: Engineered to handle high mechanical clamping pressure without structural distortion.
• Wear-Resistant T-Shaped Thread: Delivers continuous high-torque clamping action without slippage or thread wear.
• Extended 5" (125mm) Throat Opening: Accommodates wider beams, composite panels, and structural metal components.
• Precision Swivel Head: Compensates for non-parallel surfaces to prevent indentations and ensure secure contact.
• Corrosion Protection: Baked enamel finish protects the body against rust, oils, and harsh workshop environments.

Applications

• Clamping wide laminations, door panels, and heavy carpentry woodwork
• Heavy steel plate alignment, pipe welding, and metal assembly work
• Factory fabrication fixtures, jig holding, and drill press securing
• Automotive suspension, subframe repairs, and trailer maintenance
