Socket 1/2" 12 mm long, Proxxon PR23357

Proxxon PR23357 is a 1/2" drive, 12 mm long hexagon socket designed for use in mechanical, automotive and precision workshop applications. The extended length of the socket allows access to recessed or obstructed fasteners while the 1/2" drive format ensures compatibility with common ratchets, torque wrenches and extension bars. Constructed for repeated use in assembly and repair tasks, this long socket balances reach and reliable engagement with hex fasteners.

Advantages

The long 12 mm hex profile provides deeper reach than standard sockets, reducing the need to disassemble surrounding components. A 1/2" drive interface delivers greater torque capacity and broad compatibility with professional ratchets and torque tools. The design focuses on accurate hex engagement to minimise rounding of fastener heads and to improve safety and efficiency during tightening and loosening operations.

Suitable for

• Automotive repair and engine bay work where bolts are recessed
• Workshop maintenance and general mechanical assembly
• Precision tasks requiring consistent hex engagement on medium-size fasteners
• Use with torque wrenches and extension bars for controlled tightening

Key specifications

• Drive size: 1/2" (square drive)
• Socket size: 12 mm hexagon
• Length: long profile for access to recessed fasteners
• Intended use: manual ratchets, torque tools and compatible extensions
• Material and finish: durable alloy with precision-machined hex profile (manufacturer-specified)

How to use

Select the 12 mm long socket and attach it securely to a 1/2" drive ratchet or torque wrench. Engage the hexagonal socket fully onto the fastener head to ensure correct contact and reduce cam-out. For recessed fasteners, use an appropriate extension bar if additional reach or clearance is required. When using a torque wrench, apply the specified torque gradually and avoid sudden impacts; when loosening tight or corroded bolts consider controlled penetrating lubricant and steady force to prevent damage.

Usage recommendations

Inspect the socket for wear or damage before use and replace if the hex profile is rounded. Use the 1/2" drive long socket with compatible ratchets and torque tools within their rated torque limits. Store in a dry toolbox to prevent corrosion and keep extensions and accessories clean to maintain accurate engagement.
