Socket wrench Proxxon 8x9 mm 23832, double box-end wrench for hex nuts

Proxxon socket wrench 8x9 mm model 23832 is a compact double box-end wrench designed to engage 8 mm and 9 mm hex nuts and bolts. Its short, slim profile enables access in confined spaces and provides accurate seating on small fasteners used in light mechanical work, hobby projects, and maintenance tasks. The forged construction and precisely machined box ends ensure consistent contact with the flat faces of metric hex heads for controlled turning and reduced rounding.

Advantages

The double box-end design combines two adjacent metric sizes in one tool, saving space in a toolkit and reducing the need to change wrenches. Precisely machined hex sockets offer a snug fit on 8 mm and 9 mm fasteners, which improves torque transfer and lowers the risk of slippage. The compact geometry is suited for tight recesses and assemblies where a full-length spanner cannot be used. Durable material and quality finishing extend service life under normal workshop and household use.

Suitable for

• Tight-space mechanical work where access is limited
• Small automotive and motorcycle maintenance tasks
• Hobbyist and DIY assembly or disassembly of fittings
• Precision work on electrical enclosures, instruments, and appliances

Key specifications

• Metric sizes: 8 mm and 9 mm double box ends
• Compact, short-length double-ended wrench format
• Material: forged steel with machined box ends (chrome or heat-treated finish as typical for hand tools)
• Intended for use on standard metric hex nuts and bolt heads
• Suitable for manual turning; not a powered or ratcheting tool

How to use

Select the box end that matches the hex fastener size (8 mm or 9 mm), place the wrench fully over the nut or bolt head until it seats on the flat faces, and apply steady manual force to turn. Use the shorter length to reach recessed fasteners and orient the wrench so that the applied force is straight and aligned with the fastener axis to minimize slippage. If more torque is required, ensure proper grip and consider using an appropriate longer wrench or torque tool rather than forcing the compact box-end.

Usage recommendations

Inspect the fastener and the wrench seating before applying force. Avoid using the double box-end wrench with impact tools or on damaged fasteners. Keep the tool clean and lightly lubricated to prevent corrosion and maintain precise fit.
