Combination wrench 20 mm NEO Tools 09-720

NEO Tools 09-720 is a 20 mm combination wrench that integrates an open-end jaw and a closed ring end to work with hex fasteners. The open-end side enables quick engagement on nuts and bolts in confined spaces, while the ring end offers a secure fit for applying higher torque without rounding. Constructed for routine automotive, machinery maintenance and general repair tasks, this 20 mm spanner provides the basic features needed for fastening and loosening operations.

Advantages

The combination of an open jaw and a box end gives flexibility for both rapid positioning and controlled torque application. Durable material and precise machining of the contact surfaces reduce slippage and wear. The ergonomic profile ensures stable handling during use and helps reach fasteners in moderately restricted areas. The single-piece design improves strength and minimizes distortion under load.

Suitable for

• Automotive maintenance and repairs requiring a 20 mm spanner
• Assembly and disassembly of machinery components with 20 mm hex fasteners
• General household and workshop repairs involving nuts and bolts
• Maintenance tasks in plumbing or metalwork where a 20 mm wrench fits

Key specifications

• Tool type: combination wrench (open-end + ring end)
• Size: 20 mm across flats
• Contact geometry: open jaw for quick engagement; closed ring for torque application
• Construction: single-piece forged/precision-machined steel (material and heat treatment for durability)
• Finish: corrosion-resistant surface treatment for extended service life

How to use

Select the 20 mm end that suits the task: use the open-end side to slip onto the fastener quickly or the ring end for a more secure grip when applying higher torque. Position the wrench fully onto the flats of the fastener to avoid slipping, then apply steady force in the required direction. For confined spaces, use the open jaw to reposition and the ring end when a firm hold is necessary. Inspect the tool before use for signs of wear or damage and avoid using it with cheater bars or on rounded fasteners.

Usage recommendations

Maintain the contact surfaces clean and free of oil to reduce slippage. Store the wrench in a dry place to preserve the corrosion-resistant finish. Use the ring end when greater torque is needed and the open end for quick adjustments; do not apply excessive bending force to avoid tool deformation.
