Product Introduction

Industrial-Grade High-Strength Material – Crafted from premium chrome vanadium steel with quenching and tempering treatment, reaching HRC 42-45 hardness. Resistant to wear, deformation, and corrosion, ensuring long-lasting performance even in harsh working environments.
Thickened & Strike-Ready Design – Extra-thick wrench body and reinforced head structure bear direct hammer strikes without breakage. Perfect for loosening rusted, seized, or over-tightened bolts and nuts in heavy-duty applications.
Dual-End Versatility for Maximum Efficiency – Combines open end for quick fastener fitting and 12-point box end for full-contact grip, preventing slipping and protecting fastener heads. Reduces tool switching time during mechanical repair and equipment maintenance.
Professional Anti-Rust Surface Finish – Available in black oxide or electroplated coating, effectively repelling moisture and dust. Ideal for use in mining, petroleum, construction, and shipbuilding industries where tools face tough conditions.
Factory Wholesale with Customization Options – MOQ of 50 pieces per size, mixed orders acceptable. Support logo printing, size customization, and color coating to meet your brand needs. 12-month warranty against manufacturing defects.
