Socket bit 3/8" drive 12 mm long hex NEO Tools 08-187

Long 12 mm hex socket bit with 3/8" drive from NEO Tools, model 08-187. Designed to reach recessed and confined hex fasteners, this long socket bit provides extra reach compared with standard-length hex sockets. It is intended for use with hand ratchets and other compatible 3/8" drive accessories, enabling reliable fastening and loosening in automotive, maintenance and assembly tasks where a longer tool is required.

Advantages

The extended 12 mm hex profile offers improved access to bolts and screws located in deep or narrow recesses without the need for disassembly of surrounding parts. Its 3/8" drive interface ensures compatibility with a wide range of hand ratchets and adapters, delivering secure engagement and torque transfer. The longer shank reduces the risk of knuckle contact with nearby components and allows work in tighter spaces compared with standard sockets of the same diameter.

Suitable for

• Automotive repair and maintenance where fasteners are recessed
• Industrial and mechanical assembly that requires extended reach
• General household maintenance in confined or hard-to-reach locations
• Service and repair tasks using 3/8" drive ratchets and extensions

Key specifications

• Drive size: 3/8" compatible with 3/8" ratchets and adapters
• Head type: hex (6-point) for 12 mm fasteners
• Working size: 12 mm hex
• Design: long/reach type for recessed fasteners
• Intended use: manual ratchet-driven fastening and loosening

How to use

Select a 3/8" drive ratchet or adapter and fit the long 12 mm hex socket bit onto the drive square. Position the hex head over the fastener and apply steady turning force with the ratchet, keeping alignment between the bit and the fastener to avoid rounding. For obstructed or deep-set fasteners, use extensions or universal joints as needed while maintaining control of torque. Inspect the socket bit before use for wear or damage and replace it if deformation or excessive wear is visible.

Usage recommendations

Use the socket bit with hand-driven 3/8" ratchets and avoid excessive impact or power-tool use unless the bit is specifically rated for such applications. When working on corrosion-prone fasteners, apply penetrating lubricant and allow time to penetrate before attempting removal. Store the socket bit in a protective organizer to prevent damage and to keep the hex profile sharp for reliable engagement.
