The DongCheng HD071006 6-Inch (150mm) G-Clamp is a standard for construction sites, heavy fabrication workshops, and professional carpentry. Manufactured with an oversized malleable cast iron frame, it delivers substantial clamping pressure without bending or fracturing.

The hardened steel screw features coarse T-shaped threading that resists metal shaving and binding, even in dusty or grit-heavy welding environments. Featuring a generous 150mm jaw opening, heavy-duty swivel base, and a steel sliding Tommy bar handle, it offers reliable, long-lasting holding power.
