Combination Wrench Rockforce 30 mm L 345 mm Cr-V RF-75530

Rockforce Combination Wrench 30 mm, length 345 mm, is a hand tool designed for turning hexagonal fasteners. The tool features an open-end on one side and a boxed ring on the other, made from chromium‑vanadium (Cr‑V) steel to provide strength and wear resistance. Its 345 mm length offers extended reach and improved mechanical leverage for demanding automotive, industrial and maintenance tasks.

Advantages

The Cr‑V steel construction ensures a high tensile strength and resistance to deformation under torque. The combination of an open-end and a ring end gives versatility for both quick adjustments and secure full-contact turning. The 345 mm length increases leverage to handle tightly fastened bolts and nuts, while the 30 mm head size fits larger fasteners commonly found in engines, frames and heavy equipment. The tool’s machined profile provides reliable seating on fastener flats and reduces slippage during use.

Suitable for

• Tightening and loosening 30 mm hex bolts and nuts
• Automotive repair and assembly where long reach is required
• Industrial maintenance, machinery and equipment servicing
• Construction and metalwork tasks needing extra leverage

Key specifications

• Wrench type: combination (open-end and ring)
• Head size: 30 mm
• Overall length: 345 mm
• Material: chromium‑vanadium (Cr‑V) steel
• Finish: machined surface for accurate fit

How to use

Select the correct 30 mm end for the fastener type and seating. Place the open-end for quick initial turning or the ring end for full-face contact when higher torque is needed. Ensure the wrench fully engages the flats of the bolt or nut and apply steady force, pulling the wrench toward you rather than pushing when possible to reduce the risk of slipping. For stubborn fasteners, use controlled increased leverage while avoiding impact or excessive force that could damage the fastener or tool.

Usage recommendations

Inspect the wrench before use for wear or rounding on the jaws. Use hand force only; avoid striking the wrench with a hammer. Store in a dry place to prevent corrosion and periodically clean and lightly oil the tool to maintain condition and reliable fit on fasteners.
