9 mm Open & 12 Point Box Wrench – 15° Offset

This 9 mm combination wrench features an open end and a 12-point box end, both sized identically for versatile use. The open end has a thin, tapered jaw profile that fits into tight spaces, allowing quick engagement with fasteners. The 12-point box end provides a larger contact area and superior torque transfer, reducing the risk of rounding fasteners. The 15° offset angle on both ends improves knuckle clearance and ease of use in confined areas.

Manufactured from drop forged alloy steel, the wrench is heat treated and hardened for high strength, toughness, and wear resistance. It is suitable for heavy-duty applications such as marine engine maintenance, industrial machinery assembly, pipe fitting, and steel structure work. Each wrench is sold individually.
