Socket 1/2" 16 mm Hartsson 17A316Z — 6-point hexagon

Hartsson 1/2" 16 mm 6-point socket (model 17A316Z) is a hand tool designed for use with 1/2-inch drive ratchets, extensions and torque wrenches. The 6-point hexagon profile provides secure contact with 16 mm hex fasteners and helps reduce rounding and slipping under high torque. Constructed for routine mechanical maintenance and automotive repair tasks, this socket fits standard 16 mm nuts and bolts and integrates with common 1/2" drive accessory sets.

Advantages

The 6-point hexagon geometry ensures even load distribution across fastener flats, improving grip and reducing the risk of damage to bolt heads. Compatibility with 1/2" drive tools offers versatility in workshop and field environments. The socket's 16 mm opening matches widely used metric fasteners, enabling efficient work on cars, machinery and assembly components requiring this size. Durable construction provides reliable performance for repeated use in maintenance and repair operations.

Suitable for

• Automotive repairs — wheel, engine and suspension fasteners sized 16 mm
• Mechanical maintenance of industrial and agricultural equipment with 16 mm hex fasteners
• Assembly and disassembly tasks in workshops using 1/2" drive tool sets
• Use with torque wrenches and extensions for controlled tightening

Key specifications

• Drive size: 1/2 inch compatible
• Socket size: 16 mm hex
• Profile: 6-point (hexagon)
• Intended use: manual hand tool for ratchets, extensions, torque wrenches
• Common applications: automotive, mechanical maintenance, assembly

How to use

Select a compatible 1/2" drive ratchet, breaker bar or torque wrench and attach the 16 mm socket securely to the square drive. Place the socket squarely onto the 16 mm fastener, ensuring full engagement with the hex flats before applying force. For tightening, use a torque wrench set to the specified torque value for the fastener; for loosening, apply steady, controlled force to avoid slipping. Use extensions or universal joints where access is restricted, keeping the socket aligned to prevent rounding.

Usage recommendations

Inspect the socket and drive tool before use for signs of wear or damage. Use the socket only within the rated capacity of the hand tools employed and avoid impact tools unless the socket is specified as impact-rated. Clean and store in a dry place to maintain performance and prevent corrosion.
