Socket Wrench Proxxon 16 x 17 mm PR23882 - double-ended ring wrench

Proxxon socket wrench PR23882 is a compact double-ended ring (box) wrench with 16 mm and 17 mm sizes designed for secure engagement with hex fasteners. The slim profile and closed ring heads provide reliable torque transfer while reducing the risk of rounding bolt heads. This hand tool is intended for tasks that require access to bolts and nuts in confined or hard-to-reach spaces typical in automotive, bicycle and general workshop maintenance.

Advantages

The double-ended design with two adjacent metric sizes saves space in the toolbox and eliminates the need to carry two separate wrenches. Closed ring heads fully surround fasteners for improved contact and safer torque application. The compact length and slim cross-section make it easier to access recessed nuts or bolts located near obstructions. Durable material and precision machining ensure consistent fit and long service life under normal workshop conditions.

Suitable for

• Automotive maintenance: tightening and loosening 16 mm and 17 mm bolts in engine bays and undercarriage components
• Bicycle repairs where mid-range metric sizes are used on pedals, stems and axle nuts
• General workshop assembly and disassembly tasks in confined spaces
• Home maintenance jobs involving plumbing fixtures, furniture bolts and appliance fasteners

Key specifications

• Type: Double-ended ring (box) wrench
• Sizes: 16 mm and 17 mm
• Head form: Closed ring on both ends for full contact with hex fasteners
• Profile: Slim, compact design for access in restricted spaces
• Material and finish: Hardened steel with machined contact surfaces (factory-applied finish)

How to use

Select the correct end (16 mm or 17 mm) that matches the fastener size. Seat the closed ring fully over the bolt or nut, ensuring all contact points align with the flats of the fastener. Apply steady turning force, keeping the wrench aligned with the fastener axis to avoid slipping. For tight or seized fasteners, apply controlled force and avoid sudden impact loads. After use, wipe off dirt and store the wrench in a dry toolbox to prevent corrosion.

Usage recommendations

Use the wrench for its intended metric sizes and avoid using it with damaged or rounded fasteners. Do not use the ring wrench as a hammer or pry bar. For high-torque applications, consider using a torque wrench or appropriately rated tool. Regularly inspect the contact surfaces for wear and replace the tool if fit becomes loose.
