Socket Bit 3/8" Drive 8mm Proline ZR18308, 6-Point

Proline Socket Bit 3/8" Drive 8mm ZR18308 is a 6-point socket bit engineered for reliable engagement with hex fasteners. It attaches to tools with a 3/8" square drive, providing a solid connection for hand ratchets and compatible torque wrenches. The 6-point geometry reduces the risk of rounding fastener corners and concentrates torque on the flat faces of bolts and nuts for consistent performance in automotive, mechanical and workshop settings.

Advantages

The 6-point configuration ensures improved grip on hex fasteners and lowers the chance of slippage or damage to fastener corners. The 3/8" drive compatibility makes the bit suitable for a wide range of ratchets and torque tools commonly used in vehicle maintenance and general mechanical work. The compact 8 mm size is useful for confined spaces and for working with small to medium fasteners.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• General workshop fastening tasks
• Tight spaces where compact socket bits are required

Key specifications

• Drive size: 3/8" square drive (compatible with standard 3/8" tools)
• Socket size: 8 mm
• Point configuration: 6-point for improved contact with hex fasteners
• Intended use: fastening and loosening hex bolts and nuts
• Typical applications: automotive, mechanical, and general workshop use

How to use

Select a ratchet or torque tool with a 3/8" square drive and attach the Proline 8 mm 6-point socket bit by pushing it onto the drive until it seats securely. Place the socket over the hex fastener and apply controlled torque using a hand ratchet or torque wrench. For tightening, follow the torque values specified for the fastener; for loosening, apply steady force while maintaining alignment to avoid stripping. After use, remove the bit and store it in a suitable socket organizer or toolbox to prevent loss and damage.

Usage recommendations

Use the bit with tools rated for the required torque and avoid excessive impact on hand-rated bits. Inspect the socket faces regularly for wear and replace the bit if rounding or deformation appears to maintain safe and effective fastening.
