Socket Bit 6‑Point 3/8" Drive 16 mm Proline 18316

Proline 18316 is a 6-point 3/8" drive 16 mm socket bit engineered for fastening and loosening hexagonal bolts and nuts. Made from durable steel, this 16 mm socket is compatible with standard 3/8" ratchets and handles, providing a precise fit and efficient torque transfer for routine automotive, workshop, and maintenance work.

Advantages

The 6-point geometry reduces rounding of bolt heads and concentrates contact on the flat surfaces for secure engagement. A 3/8" drive interface ensures compatibility with a wide range of ratchets, torque wrenches, and extension bars. The solid steel construction offers wear resistance and consistent performance during repeated use, while the 16 mm size covers a common range of metric fasteners encountered in vehicle and equipment maintenance.

Suitable for

• Automotive repair and maintenance
• Workshop assembly and disassembly tasks
• General maintenance of machinery and equipment
• Home DIY projects involving metric fasteners

Key specifications

• Socket type: 6-point (hex) socket
• Drive size: 3/8"
• Socket size: 16 mm
• Material: durable steel construction
• Compatibility: standard 3/8" ratchets, torque wrenches and extensions

How to use

Select the 16 mm socket bit and attach it securely to a compatible 3/8" drive ratchet, handle, or extension. Place the socket squarely over the hexagonal fastener, ensuring full engagement with the 6-point profile. Apply steady torque in the required direction: clockwise to tighten and counterclockwise to loosen. For high-torque applications, use an appropriate torque wrench and follow the fastener manufacturer's torque specifications.

Usage recommendations

Inspect the socket for wear or damage before use and avoid using a worn socket on rounded or damaged fasteners. Use the 6-point socket for best contact with hexagonal heads and select a socket extension when access is restricted. Store the socket in a dry place to prevent corrosion and maintain reliable performance.
