Ring Wrench Proline 36574 — 1 pc, standard size (single-piece)

Proline ring wrench model 36574 is a single-piece closed-end wrench designed for tightening and loosening hexagonal nuts and bolts. Forged from steel and finished with chromium plating, this ring wrench offers a smooth, corrosion-resistant surface and hardened contact areas for repeated mechanical use. The ground heads provide precise seating on fasteners, reducing the risk of rounding and ensuring consistent torque transfer during automotive, mechanical and general DIY work.

Advantages

The single-piece construction increases strength and reduces flex under load, while cold forging improves overall durability and grain structure. Ground heads deliver accurate fitment to fastener flats, minimizing slipping and wear. The chromium-plated finish protects against rust and simplifies cleaning after use. This combination of features makes the wrench a reliable tool for repeated fastening tasks where closed-end contact is preferred.

Suitable for

• Automotive repair and vehicle maintenance
• Mechanical assembly and equipment servicing
• General household and DIY projects involving hex nuts and bolts
• Workshop tool sets and professional service kits

Key specifications

• Tool type: Closed (ring) wrench, single-piece construction
• Material and treatment: Cold forged steel with chromium plating
• Head finish: Ground heads for precise fit
• Quantity: Supplied as one unit
• Typical use: Designed for hexagonal nuts and bolts

How to use

Select the ring wrench that matches the fastener size and engage the closed end fully over the nut or bolt head. Apply steady force to turn the fastener, positioning your body to avoid slipping and to use controlled motion. For high-torque applications, ensure the wrench is correctly seated on the fastener flats and pull rather than push when possible to reduce the chance of injury. After use, wipe the wrench clean and store in a dry place to maintain the chromium finish.

Usage recommendations

Use this closed-end Proline ring wrench for tasks where full engagement around the fastener is required. Avoid using the tool as a hammer or pry bar, and do not apply impact force unless the wrench is specifically rated for such use. Regularly inspect the ground heads for wear and replace if rounding occurs to maintain safe and accurate operation.
