SATA ST40113SC Combination Wrench 1"

Made from high-strength steel with a corrosion-resistant chrome finish, it has laser-etched size markings for quick identification, a dual-ended design (open and box ends), an ergonomic handle, and a 1" size suitable for larger fasteners.

Off-corner loading steers the fastener contact toward the sides of the corners rather than the edge, reducing fastener rounding and providing better grip and torque transfer in demanding jobs.

The 15° offset provides extra knuckle clearance, helping you work in tight spots where a straight box end would foul against adjacent components.

It's ideal for automotive, heavy-duty, and industrial fastening tasks that involve larger fasteners and constrained spaces where a traditional straight wrench would struggle.

Match the wrench to the fastener size, apply steady torque within recommended limits, use the open end for initial loosening or breaking torque, and switch to the box end for final tightening in the proper direction.

Wipe clean after use, dry thoroughly, apply a light coat of oil to prevent rust, and store in a dry, organized toolbox to prevent corrosion and damage.

Wear gloves and eye protection, inspect the tool for cracks or deformations before use, avoid using it as a lever or pry bar, and never exceed fastener torque ratings.

Ideal for large automotive fasteners, industrial equipment maintenance, machinery repairs, and any situation requiring a tough, 1" size wrench with good access in tight spaces.
