Box-end wrench 13 mm L 170 mm PARTNER PA-3013 Cr-V

Combination box-end wrench PARTNER PA-3013 is a 13 mm closed-end hand tool with an overall length of 170 mm. Manufactured from chromium-vanadium (Cr-V) steel, the wrench is designed to deliver a secure fit on hexagonal fasteners while providing the durability and torsional resistance required for repair, assembly and maintenance tasks. Its compact length makes it suitable for work in confined spaces where leverage and control are both needed.

Advantages

The Cr-V steel construction offers enhanced strength and wear resistance compared with standard carbon steels, helping the wrench retain its shape and gripping profile under repeated use. The closed box end ensures full contact with bolt heads and nuts, reducing the risk of slippage and rounding. The 170 mm length balances torque capability with access to tight areas, and the 13 mm size covers a common fastener dimension in automotive, machinery and household applications.

Suitable for

• Automotive repair and maintenance on 13 mm fasteners
• Mechanical assembly and disassembly tasks
• Plumbing and household installations requiring a compact wrench
• Light industrial and workshop maintenance

Key specifications

• Working size: 13 mm
• Overall length: 170 mm
• Material: chromium-vanadium (Cr-V) steel
• End type: closed/box end
• Finish: metal (uncoated or factory finish as supplied)

How to use

Select the 13 mm box-end wrench and place the closed end fully onto the hexagonal fastener so that all contact faces engage. Apply steady, controlled force in the required direction to tighten or loosen the fastener, ensuring the wrench remains seated to minimize slippage. For access in confined or recessed areas, align the 170 mm handle to achieve the best combination of reach and leverage. Avoid using extensions or cheater bars that exceed the intended leverage for the tool.

Usage recommendations

Periodically inspect the box end for wear or rounding; keep the tool clean and lightly oiled to prevent corrosion. Use appropriate hand protection and apply torque within safe limits for both the fastener and the wrench to preserve tool integrity and ensure safe operation.
