Socket Wrench Double-Ended JCB 16x17 mm — JCB JCB-7521617

Double-ended socket wrench JCB 16x17 mm is a compact hand tool combining fixed 16 mm and 17 mm sockets on a single bar. Designed for manual tightening and loosening of hexagonal nuts and bolts, it offers a simple, durable solution for routine automotive, machinery maintenance and general repair work. The metal construction delivers the necessary leverage for hand operation while keeping the tool compact enough for workshop drawers and service vehicle kits.

Advantages

The tool provides two commonly used metric sizes in one piece, reducing the need to switch tools. Its fixed-socket design ensures a reliable fit on fasteners and minimizes play during use. Made from hardened metal, the wrench resists bending under typical manual torque and withstands frequent use in professional and domestic settings. The compact length and open-ended profile make it easy to reach nuts in confined spaces where larger ratchets or box wrenches cannot fit.

Suitable for

• Automotive repair and routine maintenance
• Machinery and equipment servicing
• On-site service vehicles and mobile tool kits
• Home workshops and DIY repair tasks

Key specifications

• Sockets: 16 mm and 17 mm (fixed)
• Construction: single-piece metal bar with integrated sockets
• Intended use: manual tightening and loosening of hexagonal nuts and bolts
• Form factor: double-ended, compact length for access in tight spaces

How to use

Select the end with the matching socket size and place it fully over the hexagonal fastener. Apply steady hand force in the required direction to loosen or tighten; use a controlled rocking or levering motion if additional torque is needed. Ensure the socket fully engages the fastener to avoid rounding. For stubborn fasteners, work incrementally to prevent sudden slips and inspect the tool and fastener condition regularly.

Usage recommendations

Use the wrench within typical manual torque limits and avoid applying impact or excessive force that could deform the tool or fastener. Keep the tool clean and dry; store in a toolbox or service kit to prevent corrosion. For faster or higher-torque applications, consider using a ratchet or breaker bar with appropriate sockets.
