Ring Impact Wrench Rockforce RF-79285, long 100 mm (L=400 mm)

Ring impact wrench Rockforce RF-79285, long 100 mm (L=400 mm) is a hand tool designed to apply high-impact torque to fasteners where a box-end engagement and extended reach are required. The tool combines a 100 mm ring (box) end for secure contact with nuts and bolts and a 400 mm overall length to access deep or recessed fasteners commonly encountered in automotive and industrial maintenance. Its construction is intended for repeated impact use and for situations where standard short wrenches cannot reach.

Advantages

The long 400 mm reach allows work in confined or recessed areas without sacrificing leverage. The 100 mm ring end ensures full perimeter contact with hexagonal fasteners, reducing rounding and slip. Robust construction and durable material selection improve resistance to repeated shock loads and extend service life under heavy-duty use. The design delivers concentrated torque transfer from the handle to the fastener for effective loosening and tightening under impact conditions.

Suitable for

• Automotive repair and suspension work where fasteners are recessed or hard to reach
• Industrial maintenance and machinery service requiring high-impact torque
• Construction and equipment repair with heavy or corroded nuts and bolts
• Workshops and service garages for routine disassembly and assembly tasks

Key specifications

• Ring (box) end width: 100 mm
• Overall length: 400 mm
• Tool type: long ring impact wrench for manual impact use
• Typical applications: high-torque fastening and loosening in deep or recessed locations
• Construction: impact-rated design intended for repeated shock loading

How to use

Place the 100 mm ring end squarely over the fastener so that the wrench fully engages the flats of the nut or bolt. Apply controlled blows with a suitable hammer or impact device to transfer impact torque through the wrench; avoid glancing blows that could damage the tool or fastener. When loosening stubborn or corroded fasteners, use progressive strikes and correct body positioning to maintain control. After use, inspect the ring end and shank for signs of wear or cracking and clean any debris before storage.

Usage recommendations

Use protective equipment such as eye protection and gloves when applying impact force. Match the ring size to the fastener to prevent rounding. For repetitive or high-volume impact tasks, consider periodic inspection and replacement to maintain safe performance.
