Combination Wrench 13 mm Rockforce RF-75513 L=170 mm Cr-V

Rockforce Combination Wrench 13 mm RF-75513 L=170 mm Cr-V is a compact, dual-ended hand tool designed for reliable fastening and loosening of nuts and bolts. Made from chrome-vanadium (Cr-V) steel and finished for corrosion resistance, the wrench combines an open-end jaw on one side with a boxed ring end on the other to provide both quick access and secure contact on fasteners in confined spaces. With a 170 mm overall length and a 13 mm working size, this wrench balances reach and control for routine automotive, mechanical and maintenance tasks.

Advantages

The chrome-vanadium construction ensures high strength and wear resistance while maintaining a slim profile for access in tight areas. The open-end allows rapid positioning on flat-sided fasteners and the boxed ring end delivers a more positive engagement to reduce rounding of bolt heads. The 170 mm length offers improved leverage compared with shorter spanners without being cumbersome for use in engine bays or machinery. The tool's surface treatment improves resistance to corrosion and simplifies cleaning after use.

Suitable for

• Automotive repairs and routine vehicle maintenance
• Mechanical assembly and disassembly of machinery
• General workshop and household maintenance tasks
• Work in confined or shallow-reach spaces where compact tools are required

Key specifications

• Size: 13 mm working jaw
• Overall length: 170 mm
• Material: chrome-vanadium (Cr-V) steel
• Ends: open-end on one side and boxed ring end on the other
• Finish: corrosion-resistant surface treatment

How to use

Select the 13 mm Rockforce combination wrench and position the appropriate end on the fastener. Use the open-end for quick placement on accessible bolts and the boxed ring for greater torque and reduced slippage on stubborn or rounded heads. Apply steady, controlled force and avoid sudden impacts to prevent tool or fastener damage. When working in tight spaces, orient the wrench so the slim profile reaches the fastener while keeping your hand clear of moving parts.

Usage recommendations

Inspect the wrench before use for signs of wear, distortion or corrosion. Use the boxed ring end for higher torque applications and the open-end for quick adjustments. Store in a dry toolbox to maintain the corrosion-resistant finish and avoid using the wrench with cheater bars or as a hammer to preserve tool integrity and user safety.
