Socket 1/2" 21mm long, NEO tools 08-471

Long 1/2" drive socket by NEO tools, size 21 mm. This extended socket is engineered for use with 1/2" drive ratchets and torque wrenches to reach recessed or deep-set bolts and nuts. The longer body provides additional access in tight engine bays, suspension components and machinery assemblies while maintaining a compact outside diameter for clearance in confined spaces.

Advantages

The extended length offers improved reach compared with standard sockets, enabling easier access to fasteners located in deep housings or behind obstructions. Manufactured by NEO tools, the socket is intended to provide accurate fit on 21 mm heads, reduce rounding of fasteners and withstand repeated use in workshop and industrial environments. Its robust construction supports torque transfer from ratchet or torque wrench to the fastener with minimal deformation.

Suitable for

• Automotive repair and maintenance — engine, suspension and wheel work
• Industrial equipment servicing and on-site maintenance
• Workshop and garage use with 1/2" drive tools
• Any application requiring access to deep-set or recessed fasteners

Key specifications

• Drive size: 1/2" (12.7 mm)
• Socket size: 21 mm
• Design: extended/long socket for improved reach
• Compatibility: for use with 1/2" drive ratchets and torque wrenches
• Typical use cases: automotive, industrial maintenance, workshop applications

How to use

Attach the 21 mm long socket to a compatible 1/2" drive ratchet or torque wrench by inserting the drive square into the tool and securing with the retaining mechanism if present. Position the socket squarely on the fastener head to avoid slippage, then apply controlled torque. For tight spaces, ensure the extended length is aligned to avoid binding with surrounding components. After use, clean any debris from the socket interior and inspect for wear before storage.

Usage recommendations

Use appropriate torque settings when tightening fasteners to avoid over-torquing. For power tools, verify the socket is rated for impact use before attaching to impact drivers; if not rated, use only with hand tools or torque wrenches. Store in a dry tool chest to prevent corrosion and periodically inspect for rounding or cracks that could compromise safe use.
