Key Technical Features

• Material: Forged from high-grade chrome vanadium (Cr-V) steel for maximum strength and rust resistance.

• Surface Finish: Professional satin or mirror-polish finish to resist oil and grease buildup, ensuring an easy-to-clean tool.

• 15° Offset: The box end is angled at 15° to provide clearance for fingers and easier access to recessed bolts.

• Anti-Rounding Design: The box end applies force to the flat sides of fasteners rather than the corners, preventing rounding over time.
