Socket 1/2" 12-point 19 mm, Hartsson 17C319Z

Hartsson 1/2" 12-point 19 mm socket is a hand tool engineered for fastening and loosening hexagonal nuts and bolts. Its 12-point profile permits engagement at smaller swing angles, which makes it suitable for use in confined or awkward spaces. The socket is designed for use with a 1/2" drive ratchet, torque wrench or breaker bar and is intended for automotive maintenance, equipment repair and general assembly work.

Advantages

The 12-point geometry improves accessibility on fasteners with limited rotation clearance, allowing quicker repositioning compared with 6-point sockets. A 1/2" drive interface provides compatibility with common professional ratchets and torque tools, enabling higher applied torque when required. The 19 mm size covers many standard metric fasteners used in vehicle and machinery service, offering a straightforward solution for routine mechanical tasks.

Suitable for

• Automotive repair and wheel or engine maintenance
• Industrial equipment assembly and disassembly
• Maintenance tasks in workshops and service garages
• Use with 1/2" drive ratchets, torque wrenches and breaker bars

Key specifications

• Drive size: 1/2" compatible
• Socket profile: 12-point (double-hex)
• Nominal size: 19 mm
• Intended use: hexagonal nuts and bolts
• Typical applications: automotive, maintenance, assembly

How to use

Select a matching 1/2" drive tool and fit the socket onto the ratchet, torque wrench or breaker bar. Ensure the 19 mm socket fully seats onto the hexagonal fastener before applying torque to avoid rounding. For controlled tightening, use a torque wrench and set the required torque value. When loosening fasteners, position the tool for optimal leverage and apply steady force; for seized fasteners consider using penetrating lubricant or a breaker bar.

Usage recommendations

Inspect the socket for wear or damage before use and avoid applying impact forces unless the socket is rated for impact use. Use the correct drive and socket size to reduce the risk of fastener or tool damage. Store the socket in a dry toolbox to prevent corrosion and maintain functional fit.
