Socket bit 12-point 1/2" 27 mm long STANLEY 1-86-435

STANLEY 12-point 1/2" drive socket, 27 mm long (model 1-86-435) is an extended-length hand tool designed to engage 12-point fasteners. Made for use with 1/2" ratchets, torque wrenches and breaker bars, this socket offers deeper reach than standard sockets while maintaining a compact external profile for access in confined areas. The 12-point configuration enables quick alignment on studs and bolts and is suitable for a variety of maintenance and repair tasks across automotive, industrial and household settings.

Advantages

The extended length provides improved access to recessed fasteners without sacrificing strength. The 12-point geometry allows multiple engagement positions for faster placement on bolts and studs. Precision machining ensures consistent fit and torque transfer while the robust material and finish resist wear and corrosion under typical workshop conditions.

Suitable for

• Automotive engine and transmission maintenance
• Industrial equipment assembly and disassembly
• Home repairs where recessed or hard-to-reach fasteners are present
• Use with 1/2" drive ratchets, torque wrenches and breaker bars

Key specifications

• Drive size: 1/2 inch
• Socket geometry: 12-point
• Nominal socket size (internal): 27 mm
• Length: extended/long
• Intended use: hand tool for fastening and loosening bolts and nuts

How to use

Select a 1/2" drive ratchet, breaker bar or torque wrench and place the socket over the fastener so the 12-point recess engages the bolt or nut. Apply steady force through the drive tool, taking care to maintain alignment to avoid rounding. For torque-critical applications, use a calibrated torque wrench and follow the specified torque sequence and values for the fastener and assembly. After use, wipe clean and store in a socket rail or toolbox to prevent damage and corrosion.

Usage recommendations

Use this socket with tools rated for 1/2" drive; avoid impact tools unless the socket is explicitly rated for impact use. Inspect the socket and fastener for wear before applying high torque, and replace damaged tools to maintain safe, reliable performance.
