Flat Ring Combination Wrench 36 mm JCB - 36mm open and ring end wrench

The Flat Ring Combination Wrench 36 mm by JCB is a dual-ended hand tool designed to tighten and loosen 36 mm nuts and bolts. One end features a flat open jaw for rapid engagement on fasteners in confined spaces, while the ring end provides a full-contact grip to minimize slippage and round-off during higher-torque applications. The wrench is intended for workshop, automotive and industrial maintenance where a reliable 36 mm spanner is required.

Advantages

The combination of an open (flat) end and a ring end gives flexibility for different fastening situations: the open jaw allows quick placement and turning on partially exposed fasteners, while the ring end offers improved torque transfer and a secure fit. The flat profile helps access tight spaces and reduces interference with surrounding components. Manufactured to withstand routine workshop use, the tool provides consistent performance for mechanical and maintenance tasks.

Suitable for

• Automotive repair and wheel or suspension work requiring 36 mm fastening
• Mechanical assembly and disassembly of machinery with 36 mm nuts or bolts
• Industrial maintenance where a durable 36 mm hand tool is needed
• Workshop toolkits for professional technicians and mechanics

Key specifications

• Wrench size: 36 mm working jaw and ring diameter
• Type: combination wrench with open (flat) end and ring end
• Profile: flat/low-profile body for access in confined areas
• Material properties: heat-treated steel construction for strength and wear resistance
• Finish: corrosion-resistant surface treatment for durability in workshop environments

How to use

Select the 36 mm end appropriate to the task: use the open (flat) end for quick engagement on fasteners with some clearance, and use the ring end when higher torque and a secure grip are required. Position the wrench so that force is applied along the handle axis to reduce the risk of rounding the fastener. For stubborn or seized fasteners, apply steady increasing torque rather than sudden impacts. Inspect the contact surfaces of the nut or bolt and the wrench before use to ensure proper fit and reduce wear.

Usage recommendations

For safe and long-lasting performance, store the wrench in a dry toolbox, clean it after use to remove oil and debris, and avoid using the tool as a hammer or pry bar. When working on critical fastenings, confirm the correct torque requirements and use appropriate torque control tools where necessary.
