Proxxon ratcheting double-ring wrench 16x18 mm Speeder — narrow, ratchet head

Proxxon ratcheting double-ring wrench 16x18 mm Speeder — narrow, ratchet head is a compact hand tool designed for working in confined spaces. It combines two ring ends in adjacent sizes, 16 mm and 18 mm, with a narrow-profile body that allows access to tight fasteners. The integrated ratchet mechanism in each head enables continuous rotation without the need to remove and reposition the wrench, making it suitable for repetitive fastening and fine torque applications.

Advantages

The narrow-profile construction reduces interference in cramped work areas while preserving ring-end engagement on bolts and nuts. The built-in ratcheting action provides reversible operation for forward and reverse turning, improving efficiency when loosening or tightening fasteners. The dual-size design eliminates the need to switch tools frequently, and the solid metal construction offers reliable torque transfer and long service life.

Suitable for

• Automotive repair and maintenance where space around fasteners is limited
• Mechanical assembly and disassembly of machinery and equipment
• Workshop and professional maintenance tasks requiring precise, repeated turning
• HVAC, plumbing, and electrical applications with confined access

Key specifications

• Wrench sizes: 16 mm and 18 mm
• Type: double-ring (box) wrench with ratcheting heads
• Profile: narrow design for confined spaces
• Drive action: integrated ratchet mechanism with reversible direction
• Material: hardened steel alloy for strength and wear resistance

How to use

Select the appropriate ring end (16 mm or 18 mm) and place it over the fastener so the ring fully seats on the nut or bolt head. Operate the ratcheting head in the desired direction by setting the reversible mechanism, then apply steady, controlled force to turn the fastener. For best engagement, ensure the wrench is properly aligned and the ring is fully engaged before applying torque. Reverse the ratchet to change turning direction without removing the wrench from the fastener.

Usage recommendations

Use the wrench for tasks within its size range and avoid excessive impact or hammering. Keep contact surfaces clean and free of debris to maintain proper engagement. For high-torque applications, consider using the appropriate larger tool designed for such loads and inspect the wrench regularly for wear or damage.
