## Summary description

Proline socket bit with 3/8" drive and 8 mm 6-point configuration (model ZR18308). Designed for fastening and loosening hex fasteners, it fits hand ratchets and compatible torque tools with a 3/8" square drive. Suitable for automotive, mechanical and general workshop use where a 6-point contact reduces rounding of fastener corners.

## Long description

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

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.
