Socket 12 mm 12-point 1/2" Proxxon PR23307

12 mm 12-point socket with a 1/2" drive from Proxxon, model PR23307, is designed to transfer torque to 12-point fasteners in workshop and automotive environments. The compact geometry of the 12-point profile allows engagement in confined spaces and on fasteners with limited access, while the 1/2" drive makes the socket compatible with common ratchets, extensions and torque tools used in maintenance, repair and assembly.

Advantages

The 12-point configuration enables multiple engagement positions on hexagonal and 12-point bolts, reducing the need to reposition the tool. Machined internal faces provide accurate seating on fasteners, improving torque transfer and minimising rounding. The 1/2" drive size ensures compatibility with a wide range of hand and power torque tools, and the socket's compact length facilitates work in tight engine bays and machinery housings.

Suitable for

• Automotive maintenance and repair where access is restricted
• General workshop fastening and loosening tasks
• Assembly work with 12-point fasteners
• Use with 1/2" ratchets, torque wrenches and extensions

Key specifications

• Nominal size: 12 mm socket opening
• Point count: 12-point internal profile
• Drive connection: 1/2" drive
• Material and finish: hardened steel with corrosion-resistant surface treatment
• Application: compatible with ratchets, torque wrenches and extensions for maintenance and assembly

How to use

Select the 12 mm 12-point socket and attach it securely to a 1/2" drive ratchet, torque wrench or extension. Place the socket fully onto the fastener so the internal faces seat evenly. Apply steady torque using the appropriate tool; when using a torque wrench, set the correct torque value for the fastener to avoid over-tightening. After use, detach the socket, clean off debris, and store it in a socket rail or toolbox to maintain service life.

Usage recommendations

For best results, use the socket with correctly sized tools and appropriate torque settings; avoid impact tools unless the socket is specifically rated for impact use. Inspect fastener and socket contact surfaces for wear before applying high torque.
