SATA ST40244SC Combination Wrench 38mm

Key specs include high-strength steel construction, a corrosion-resistant chrome finish, laser-etched size markings for quick identification, and an ergonomic non-slip handle. The tool is sized at 38mm for large fasteners and offers increased leverage for easier loosening and tightening.

It's ideal for automotive, mechanical, and industrial tasks that involve large fasteners. Use it for loosening or tightening big bolts, especially where space is limited and high torque is needed.

Use the open end for quick fitting and removal of fasteners in accessible areas. Switch to the box end for high-torque applications or when you need a stronger grip on the fastener. The 15° offset box end provides knuckle clearance in tight spaces.

The 15° offset on the box end reduces knuckle contact and increases clearance in tight spots, making it easier to apply torque without hitting adjacent components.

Wipe the wrench after use, keep it dry, and apply a light coat of oil if needed. Store it in a dry place away from moisture to preserve the chrome finish and prevent corrosion.

Off-corner loading helps improve grip on fasteners and reduces the likelihood of rounding the corners, especially on hex heads or square nuts, by distributing contact over a larger area.

These vary by fastener size and leverage, so choose the one that matches your application.

Measure the fastener head or use the tool that matches the fastener’s size. For large metric fasteners, a 38mm wrench like the ST40244SC provides the proper fit and leverage. Avoid using a wrench that’s undersized or oversized for the fastener to prevent rounding or damage.

This 38mm wrench is designed for metric fasteners. For imperial/SAE fasteners, choose a size that matches the fastener across flats to ensure a proper fit and avoid slippage.

Regularly inspect for cracks or wear, keep the chrome finish clean and dry, apply a light protective oil if exposed to moisture, and store in a dry toolbox or on a rack to prevent contact with corrosive substances.
