Combination wrench AWTools 42 mm, AWTools AW39802

Combination wrench AWTools 42 mm is a hand tool with an open-end on one side and a boxed (ring) end on the other, sized for 42 mm fasteners. It is intended for tightening and loosening nuts and bolts of that size and is suitable for automotive, industrial and general maintenance tasks where a 42 mm wrench is required. The solid one-piece construction and the two different end types make it a versatile tool for access-restricted areas and for applying torque without rounding fastener edges.

Advantages

The AWTools 42 mm combination wrench provides the convenience of an open-end for quick placement and a boxed end for secure engagement and higher torque. The ring end reduces slippage and distributes load evenly across the fastener, while the open end allows work in tighter spaces. Its robust construction ensures consistent performance under repeated use and helps maintain correct fastener geometry.

Suitable for

• Automotive repair and maintenance tasks involving 42 mm nuts and bolts
• Industrial machinery assembly and servicing
• Workshop and field maintenance where a single-size wrench is needed

Key specifications

• Wrench type: combination (open-end and boxed/ring end)
• Size: 42 mm across flats
• Material: alloy steel (heat-treated) for strength and wear resistance
• Finish: corrosion-resistant plated or polished surface
• Profile: boxed end designed for full contact with fastener

How to use

Select the 42 mm end that best fits the fastener and position the open or boxed end securely on the nut or bolt head. For initial loosening or quick adjustments, use the open-end side; for final tightening or when higher torque and reduced slippage are required, use the boxed end. Apply steady, controlled force in the correct turning direction and avoid sudden impacts. Ensure the wrench is fully seated on the fastener to minimize rounding and check for wear before use.

Usage recommendations

Use with appropriate safety equipment and avoid using the wrench as a hammer or lever extender. For heavily corroded or seized fasteners, consider applying penetrating lubricant and use correct techniques to prevent tool or fastener damage.
