Ring wrench Proxxon 34 mm model 23933, closed-end hand tool for nuts and bolts

Proxxon ring wrench 34 mm model 23933 is a closed-end hand tool designed to fit 34 mm hexagonal nuts and bolts. Manufactured to provide a full-circumference grip, this single-size ring wrench reduces slipping and rounding of fastener heads. The tool is intended for use in mechanical repairs, assembly and general maintenance in automotive, industrial and workshop settings.

Advantages

The closed-end design offers contact on all sides of the fastener head, improving torque transfer and reducing the chance of rounding. A single-size construction simplifies selection when working with consistently sized fasteners. The Proxxon ring wrench is made to withstand repeated use under normal workshop conditions and provides a compact, easy-to-handle form factor that fits into tighter spaces compared with long-handled wrenches.

Suitable for

• Tightening and loosening 34 mm hex nuts and bolts
• Automotive maintenance and repair tasks
• Industrial assembly and equipment servicing
• Workshop maintenance and mechanical installations

Key specifications

• Working size: 34 mm across flats
• Tool type: closed-end (ring) wrench, single size
• Contact profile: full-circumference engagement for hex fasteners
• Intended use: manual tightening and loosening of nuts and bolts
• Typical applications: automotive, industrial, workshop maintenance

How to use

Select the 34 mm ring wrench and position it fully over the nut or bolt head so the wrench seats on all contact faces. Apply steady, controlled force to the wrench handle in the appropriate direction to tighten or loosen the fastener. Avoid sudden impacts or excessive force beyond recommended torque values for the fastener; use a torque-limiting device if a precise torque is required. After use, clean visible debris from the wrench and store it in a dry place to prevent corrosion.

Usage recommendations

Use the Proxxon 34 mm ring wrench for fasteners that match the 34 mm size and ensure full seating before applying force. For stuck or corroded fasteners, apply penetrating lubricant and allow time to work before attempting to turn. Do not use the tool as a hammer or pry bar, and inspect the wrench periodically for wear or damage.
