Socket Bit Proline 3/8" 6mm 6-point (ZR18306)

Proline 3/8" 6mm 6-point socket bit is a compact accessory designed for use with 3/8" drive ratchets, extensions and compatible power tool adapters. The 6-point profile fits hex head fasteners securely to reduce rounding and ensure controlled torque transfer. This socket bit is intended for tasks that require a precise 6mm engagement, including automotive repairs, mechanical maintenance and general fastening work.

Advantages

The 6-point geometry provides full-face contact with hex fasteners, improving grip and reducing the risk of damage. The 3/8" drive interface ensures compatibility with a wide range of hand and power tool accessories, enabling quick changes and flexible use. Its compact length makes it suitable for working in confined spaces while maintaining torque transmission accuracy.

Suitable for

• Automotive repairs and component assembly
• Mechanical maintenance and machinery servicing
• General household and workshop fastening tasks
• Use with 3/8" drive ratchets, extensions and adapters

Key specifications

• Drive size: 3/8" compatible interface
• Socket size: 6 mm hex
• Point profile: 6-point (hex)
• Form factor: compact/short socket bit suitable for restricted spaces
• Material: hardened tool steel (as typical for socket bits)

How to use

Select the Proline 6mm socket bit and insert it into a 3/8" drive ratchet, extension or power-tool adapter. Seat the 6-point profile fully onto the hex fastener head before applying torque to avoid slipping. For manual operation, apply steady, even force; for powered tools, use controlled speed and avoid excessive impact settings to prevent fastener or bit damage. Remove the bit by pulling it from the drive once the task is complete.

Usage recommendations

Inspect the socket bit and fastener for wear or damage before use. Use the correct drive and maintain secure seating to minimize rounding. For high-torque or repeated use, consider using appropriate extensions or impact-rated accessories if available; do not exceed recommended tool limits.
