Hand striking flat wrench Rockforce RF-79150, 50 mm jaw, 270 mm length

Klucz płaski do pobijania 50mm (L-270mm) from Rockforce is a heavy-duty striking open-end wrench designed for applications requiring impact force. The tool features a 50 mm jaw opening and a total length of 270 mm, built to withstand hammer blows for loosening or tightening large fasteners in maintenance, industrial or construction settings. Constructed from heat-treated steel with a matte finish, the wrench provides a balance of strength and durability while the flat striking surface accepts direct hammer strikes to apply controlled impact torque.

Advantages

The Rockforce striking open-end wrench delivers a robust, single-piece construction that reduces the risk of deformation under impact. Its 50 mm opening and 270 mm length provide effective leverage without excessive bulk, and the heat-treated steel construction ensures long service life in demanding environments. The flat hammer face is integrated into the design to enable safe and repeatable striking, while the wrench profile is shaped for solid contact with hexagonal fasteners to minimize slipping.

Suitable for

• Maintenance and repair of industrial machinery with large hex fasteners
• Construction and assembly tasks requiring impact loosening or tightening
• Automotive heavy-duty service and agricultural equipment maintenance
• Workshops and service centers handling bolted joints exposed to corrosion or seizing

Key specifications

• Jaw opening: 50 mm
• Total length: 270 mm
• Material: heat-treated steel
• Finish: matte surface
• Design: open-end striking wrench with integrated flat hammer face

How to use

Position the 50 mm jaws securely onto the flats of the fastener to ensure full contact with the wrench. Apply steady manual pressure to set the wrench on the fastener, then deliver controlled hammer blows to the flat striking face if additional impact torque is required. Avoid off-angle strikes and ensure the wrench is seated squarely to reduce the risk of rounding the fastener. After use, clean debris from the jaws and inspect for deformation or cracks before storing the tool in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves when applying hammer strikes. Do not use the wrench on fasteners with dimensions significantly different from 50 mm. Periodically inspect the striking face and jaws for wear; replace the tool if any structural damage is detected.
