Socket 9 mm 12-point 1/2" drive Proxxon PR23304

Proxxon 9 mm 12-point socket with 1/2" drive (model PR23304) is a compact tool accessory engineered for working with 12-point nuts and bolts in confined spaces. The small-diameter socket provides multiple contact points for improved engagement on compatible 12-point fasteners while fitting standard 1/2" drive ratchets, torque wrenches and extensions. It is intended for repair, maintenance and mechanical tasks where space is restricted and a reliable connection between drive tool and fastener is required.

Advantages

The 12-point design enables quicker alignment with fasteners and allows use on both hexagonal and 12-point heads where appropriate. Its 9 mm profile is suitable for tight recesses and narrow clearance areas. Built to fit a 1/2" drive, the socket integrates with widely used ratchets and torque tools, enabling accurate application of torque when required. The compact form factor simplifies handling in constrained working environments.

Suitable for

• Automotive repair and maintenance in tight engine bays
• Mechanical assembly and disassembly where space is limited
• Industrial equipment servicing with 12-point fasteners
• Use with 1/2" drive ratchets, torque wrenches and extension bars

Key specifications

• Sockets size: 9 mm nominal
• Point configuration: 12-point internal profile for multi-surface engagement
• Drive connection: 1/2" square drive interface
• Application: designed for use on 12-point and compatible hexagonal fasteners in restricted spaces
• Form factor: compact, low-profile socket body for limited clearance

How to use

Select the 9 mm 12-point socket and attach it securely to a compatible 1/2" drive ratchet, extension or torque wrench. Position the socket over the fastener head so that the 12-point recess fully seats onto the bolt or nut. Apply steady turning force, taking care to maintain alignment to avoid rounding the fastener. When using a torque wrench, confirm the required torque value for the application before tightening.

Usage recommendations

Use the socket on fasteners that match the 9 mm size and 12-point profile to ensure proper engagement. Avoid excessive impact or misuse with unsuitable power tools; if required, use impact-rated sockets made for high-impact drivers. Regularly inspect the socket for wear or damage and replace it if rounding or cracking appears.
