Socket 12-point 1/2" 16 mm Hartsson 17C316Z, chrome vanadium

Hartsson 12-point socket, 1/2" drive, 16 mm size (model 17C316Z) is a chrome vanadium tool designed for fastening and loosening hexagonal fasteners in automotive and mechanical applications. The 12-point profile allows engagement on bolts and nuts in confined spaces and at smaller approach angles than a 6-point socket. Built for compatibility with 1/2" ratchets, extensions and torque tools, this socket is intended for repair, maintenance and assembly tasks where precise fit and reliable torque transfer are required.

Advantages

The socket is manufactured from chrome vanadium steel for high strength and durability under repeated use. Its 12-point internal geometry enables quicker positioning on fasteners and improved access in tight work areas. The 1/2" drive interface provides broad compatibility with common hand tools and torque wrenches. A machined finish ensures accurate fit to fasteners and reduces the risk of rounding heads when used correctly.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Work in confined spaces or where angled access is limited
• Use with 1/2" ratchets, extensions and torque tools

Key specifications

• Drive size: 1/2 inch compatible interface
• Socket profile: 12-point internal geometry for hexagonal fasteners
• Socket size: 16 mm working width
• Material: chrome vanadium steel
• Finish: machined/chrome-plated surface for corrosion resistance and easy cleaning

How to use

Select the 16 mm socket for the matching hexagonal fastener and attach it securely to a 1/2" ratchet, extension or torque wrench. Ensure the socket fully seats on the fastener before applying force. Turn the ratchet or wrench in the required direction to tighten or loosen the fastener, applying steady, controlled torque to avoid slipping. When using with a torque tool, follow the tool manufacturer’s settings and limits to achieve the correct torque value.

Usage recommendations

Inspect the socket and fastener for damage or wear before use. Use the 12-point profile where faster positioning is needed or when access angles are restricted, and prefer a 6-point socket for high-torque applications on rounded or damaged fasteners. Store the socket dry and clean, and avoid impact use with powered impact tools unless the socket is specifically rated for impact service.
