Socket 12 mm 3/8" Proxxon PR23540 — deep impact socket

Proxxon 12 mm 3/8" deep impact socket PR23540 is a precision hand-tool accessory designed for use with 3/8-inch drive ratchets and torque tools. Engineered to reach recessed fasteners, this deep socket provides secure engagement and dependable torque transmission in confined or hard-to-reach locations. The socket's dimensions and profile are optimized for mechanical maintenance, automotive repairs and assembly work where additional reach and impact compatibility are required.

Advantages

The deep design allows access to nuts and bolts set below the workpiece surface, reducing the need to disassemble surrounding components. Manufactured from impact-rated material, the socket withstands repeated use with impact wrenches and pneumatic tools while maintaining drive-fit integrity. A precise internal profile minimizes rounding of fastener corners and ensures efficient power transfer from 3/8-inch drive tools.

Suitable for

• Automotive repairs — wheel bolts, engine components, and undercarriage fasteners
• Mechanical maintenance — machinery assembly and service where recessed nuts are present
• Equipment installation — fastening in confined spaces and panels
• Workshop and professional service use with 3/8" drive ratchets and impact tools

Key specifications

• Drive size: 3/8" compatible
• Socket size: 12 mm
• Type: deep impact socket suitable for impact tools
• Material: impact-rated hardened steel (heat treated for durability)
• Finish: protective surface treatment to resist corrosion and wear

How to use

Select the 12 mm deep socket and attach it securely to a compatible 3/8" drive ratchet, breaker bar or impact wrench. Position the socket over the recessed fastener ensuring full seating on the nut or bolt head, then apply torque progressively. When using an impact tool, operate at recommended settings for the fastener type to avoid over-torquing. After use, clean the socket and store it in a dry tool roll or case to maintain condition.

Usage recommendations

Use with properly rated 3/8" drive impact tools and appropriate torque settings. Inspect the socket for wear or damage before use and replace if cracking or rounding is visible. For best results on sensitive fasteners, verify torque with a calibrated torque wrench after impact tightening.
