Socket Bit 3/8" 21 mm long, 6-point for nuts and bolts, NEO tools 08-196

Long 6-point socket bit with a 3/8" drive and 21 mm head size from NEO tools. The extended geometry provides additional reach to access recessed or hard-to-reach hexagonal nuts and bolts while remaining compatible with standard 3/8" drive ratchets and extensions. Constructed for general maintenance use, this socket bit is intended for controlled tightening and loosening tasks in automotive, mechanical and workshop environments where an extended reach and secure 6-point engagement are needed.

Advantages

The 6-point configuration delivers full-corner contact for minimized rounding of fasteners and improved torque transfer. The 21 mm head and longer length enable access to recessed nuts and bolts that standard sockets cannot reach. Compatibility with standard 3/8" drive tools ensures straightforward integration with existing ratchets and extensions, while the single-piece socket bit design provides stable, concentric fit and reliable operation under typical workshop loads.

Suitable for

• Automotive repairs where fasteners are recessed or located in tight engine bays
• Mechanical assembly and disassembly of machinery and equipment
• General maintenance and workshop tasks requiring extended-reach socket access
• Use with 3/8" drive ratchets and extension bars for increased reach

Key specifications

• Drive size: 3/8" compatible
• Head size: 21 mm
• Point configuration: 6-point (hex)
• Extended length: long socket geometry for recessed fasteners
• Material and finish: durable metal alloy with workshop-grade surface treatment

How to use

Attach the socket bit to a compatible 3/8" drive ratchet or extension bar until it seats securely. Place the 21 mm hex opening over the fastener, ensuring full engagement of the 6 points to reduce risk of slippage. Apply steady torque to tighten or loosen the nut or bolt; for stubborn fasteners, use controlled incremental force and, if required, an extension bar for additional reach. After use, wipe clean and store in a socket set or tool organizer to prevent corrosion and maintain fit.

Usage recommendations

For best results, use the socket with calibrated 3/8" ratchets and avoid excessive impact force beyond the tool's intended manual torque range. Inspect the socket and fastener for wear before applying high torque. When accessing deep-set bolts, use a matching extension bar to keep the ratchet handle clear of obstructions and maintain safe leverage.
