Ring wrench Proxxon Speeder PR23250 17 x 19 mm — slim ratcheting double box-end

Proxxon Speeder PR23250 17 x 19 mm — slim ratcheting double box-end is a compact, low-profile ring wrench designed for working in confined spaces. The tool combines two box ends in a single slim body with a built-in ratchet mechanism, enabling continuous turning of fasteners without repeated repositioning. Machined contact faces and a narrow head profile support access to tight engine bays, machinery housings and maintenance assemblies where clearance is limited.

Advantages

The slim ratcheting double box-end provides fast operation in restricted areas while maintaining reliable engagement with hex fasteners. A narrow profile reduces the risk of interference with surrounding components, and the ratchet action allows efficient clockwise and counterclockwise movement without removing the wrench from the nut or bolt. The dual-size design (17 mm and 19 mm) eliminates the need to switch tools for adjacent fastener sizes, improving workflow during repairs and service tasks.

Suitable for

• Automotive repair and servicing where access behind engine components is limited
• Mechanical assembly and maintenance in tight machine housings
• Plumbing and HVAC installations requiring work in narrow spaces
• General workshop tasks where precise, repeatable turning is needed

Key specifications

• Box-end sizes: 17 mm and 19 mm
• Slim, low-profile head for confined-space access
• Integrated ratchet mechanism for continuous turning
• Double-ended ring wrench design
• Precision-machined contact faces for secure grip

How to use

Select the box end that corresponds to the fastener size and place the ring over the nut or bolt head. Apply steady pressure and use the ratcheting action to turn the fastener in the desired direction; the mechanism enables back-and-forth movement without lifting the wrench. For stubborn or heavily torqued fasteners, confirm the wrench engagement on all contact faces before applying additional force to avoid rounding. After use, wipe the tool clean and store in a dry place to preserve the ratchet mechanism.

Usage recommendations

Use the slim ratcheting ring wrench in combination with standard torque practices: avoid sudden shocks, do not use as a hammer, and do not extend the handle with improvised cheater bars. Periodically inspect and lightly lubricate the ratchet mechanism if performance becomes stiff, and choose the correct end for the fastener to maintain optimal grip and reduce wear.
