Open-End and Ring Wrench AWTools 38 mm, model AW39798

AWTools Open-End and Ring Wrench 38 mm, model AW39798, is a hand tool designed for tightening and loosening hexagonal nuts and bolts with a 38 mm head. The combination design pairs an open-end jaw for rapid placement and an offset closed ring for secure torque application. The tool is intended for use in automotive repair, industrial maintenance, and general mechanical tasks where 38 mm fasteners are present.

Advantages

The dual-head configuration of the AWTools 38 mm wrench provides flexibility between quick engagement with the open end and reliable grip with the ring end. The combination format reduces the need to switch tools when alternating between accessibility and torque control. The fixed 38 mm size offers consistency for repeated use on identically sized fasteners, supporting efficient workflow in professional and hobby settings.

Suitable for

• Automotive wheel nuts and suspension fasteners sized 38 mm
• Industrial machinery maintenance using 38 mm hex bolts
• General mechanical and assembly tasks with 38 mm hardware
• Field service and workshop repairs where both quick access and secure torque are required

Key specifications

• Tool type: combination wrench (open-end and ring)
• Nominal size: 38 mm across flats
• Application: hexagonal nuts and bolts
• Ends: one open jaw and one closed ring
• Typical use cases: automotive, industrial maintenance, general repairs

How to use

Select the AWTools 38 mm combination wrench and position the open-end jaw over the fastener for quick initial engagement or use the ring end for final tightening and loosening where a secure grip is required. Apply steady, controlled force to avoid rounding the fastener; when working in confined spaces, use the open end to reposition and the ring end to apply torque. Inspect the fastener and wrench contact surfaces before use to ensure proper seating and safe operation.

Usage recommendations

Use the ring end for final torque application to reduce the risk of slipping and rounding. Avoid applying impact force with the wrench; for very tight fasteners, consider using appropriate torque tools or breaking bars designed for impact-rated applications. Store the wrench in a dry place to prevent corrosion and periodically check for wear or deformation.
