Ring wrench NEO tools 03-031 — 235 mm length, 486 g, single piece

NEO tools 03-031 is a single-piece ring wrench designed for ring-shaped engagement with fasteners. With an overall length of 235 mm and a weight of 486 g, this compact hand tool suits general mechanical, automotive and maintenance work where access and controlled torque are required. Constructed from forged chromium-vanadium (CrV) steel, the tool offers a balance of strength and durability for everyday workshop tasks.

Advantages

The adjustable, reversible ring spanner covers a continuously adjustable range from 5 to 27 mm, allowing one tool to fit multiple fastener sizes and reducing the need for many fixed wrenches. Four bolt contact points provide improved force transfer and minimize rounding of nuts and bolts. Forged CrV steel construction increases resistance to bending and wear, while the single-piece design simplifies handling and provides stable torque application.

Suitable for

• General mechanical repairs and assembly
• Automotive maintenance and servicing
• Industrial and plant maintenance tasks
• Plumbing and household fastening jobs requiring ring engagement
• Situations where metric and inch screws must be handled with one tool

Key specifications

• Length (depth): 235 mm
• Weight: 486 g
• Material: forged chromium-vanadium (CrV) steel
• Adjustable range: 5–27 mm (continuously adjustable)
• Design: single-piece, reversible ring spanner
• Contact points: four bolt contact points for high power transfer
• Compatibility: suitable for metric and inch fasteners

How to use

Select the required size by adjusting the ring spanner to match the fastener head. Position the ring over the nut or bolt so that the four contact points engage securely, then apply steady torque in the required direction. Use the reversible feature to switch orientation if access or turning direction requires it. For stubborn or rusted fasteners, apply force gradually and consider using penetrating lubricant to reduce the risk of damage to the fastener.

Usage recommendations

Inspect the tool for wear or deformation before use and ensure the adjustable mechanism is free of debris. Do not use the wrench on damaged or rounded fasteners; avoid applying impact force with a hammer. Store the spanner in a dry place and periodically clean and lightly oil the adjustable parts to maintain smooth operation and prolong service life.
