Ring Spanner Offset MEGA 16 x 17 mm 36546

The MEGA Ring Spanner Offset 16 x 17 mm (model 36546) is a double-ended closed-ring hand tool with two adjacent metric sizes designed for working in confined or angled spaces. Each end is formed as a full ring to provide a secure grip on hex heads and bolts, while the offset profile improves access where a straight spanner cannot reach. The tool is intended for general mechanical, automotive and maintenance tasks that require reliable torque transfer in restricted environments.

Advantages

The offset ring spanner offers improved clearance and hand safety compared with straight ring wrenches by keeping knuckles away from surfaces while allowing use at an angle. Closed-ring ends reduce the risk of slipping and rounding of fastener corners, delivering a firmer contact on hex heads. The dual-size configuration (16 mm and 17 mm) saves tool changes in common applications and helps streamline small repair and maintenance jobs.

Suitable for

• Automotive repairs where space around engine components is limited
• Mechanical assembly and disassembly of machinery with recessed bolts
• Routine workshop maintenance and installations in tight locations

Key specifications

• Two closed ring ends: 16 mm and 17 mm
• Offset profile for improved access in confined spaces
• Material: hardened tool steel suitable for hand-tool use
• Finish: corrosion-resistant surface treatment to extend service life
• Designed for hexagonal fasteners and bolts

How to use

Select the ring end matching the fastener size (16 mm or 17 mm) and slide the closed ring fully over the hex head. Apply steady turning force while keeping the spanner seating squarely on the fastener to avoid camming or rounding. Use the offset to access bolts recessed behind obstructions or where a straight wrench cannot be aligned. Inspect the fastener and tool seating frequently and avoid excessive impact or leverage beyond hand force to prevent tool or fastener damage.

Usage recommendations

For safe and effective use, keep the ring spanner clean and free of oil for a secure grip, store it in a tool roll or box to avoid nicks on the ring edges, and select the correct end to minimize wear on fasteners. Do not use the tool with extenders or hammering; if higher torque is required, use an appropriately sized socket and torque wrench.
