Flat Ring Spanner Dedra 20 x 22 mm 1479

Flat Ring Spanner Dedra 20 x 22 mm 1479 is a double-ended, low-profile hand tool designed for tightening and loosening hex nuts and bolts with 20 mm and 22 mm heads. The spanner features closed ring ends on both sides, providing full contact with fastener faces to reduce slippage and distribute torque evenly. Its flat design makes it suitable for working in confined or low-clearance spaces where a standard open-end wrench cannot reach.

Advantages

The ring ends ensure a secure grip on fasteners and reduce the risk of rounding. The flat construction allows access in tight locations and helps apply torque with a controlled hand motion. Made for general workshop and household use, the spanner offers straightforward functionality without moving parts and is compatible with metric 20 mm and 22 mm hex heads.

Suitable for

• Automotive maintenance and repair where low-profile access is required
• Mechanical assembly and disassembly of machinery with 20 mm and 22 mm fasteners
• Household and DIY projects involving metric nuts and bolts
• Tight or confined spaces where ring-end contact improves grip and safety

Key specifications

• Type: flat double-ended ring spanner
• Sizes: 20 mm and 22 mm ring ends
• Ends: closed ring on both sides for full-face engagement
• Profile: low-profile/flat design for limited-clearance use
• Material: durable hand-tool steel suitable for routine tightening and loosening tasks

How to use

Select the ring end that matches the fastener size (20 mm or 22 mm). Place the ring fully over the hex head so the spanner sits flush against the fastener faces. Apply steady, controlled force in the appropriate direction to tighten or loosen the fastener. For best results, ensure the spanner is fully engaged with the fastener before applying torque and avoid using excessive impact force that could damage the tool or fastener.

Usage recommendations

Inspect the spanner for wear or damage before use and keep the contact surfaces clean. Use appropriate personal protective equipment when working on vehicles or machinery. For stubborn or corroded fasteners, consider applying penetrating lubricant and use controlled, incremental force rather than sudden impact to reduce the risk of rounding the fastener or damaging the tool.
