Hartsson 1/2" 19 mm 6-point socket model 17A319Z is a hand tool designed for use with 1/2" drive ratchets and torque tools. The 6-point internal profile is shaped to fit hex fasteners, providing stable contact across flats to reduce rounding and improve torque transfer. Intended for automotive maintenance, mechanical assembly and general repair work, this 19 mm socket is a compact, single-size solution for fastening and loosening 19 mm hex nuts and bolts.

Advantages

The 6-point design offers secure engagement with hex heads, minimizing slippage and damage to fasteners. Built for compatibility with 1/2" drive tools, the socket enables reliable torque application when used with ratchets or torque wrenches. Its single-size construction ensures straightforward selection and storage when a 19 mm socket is required, and the standardized interface allows quick attachment and removal from drive tools.

Suitable for

• Automotive maintenance and wheel or engine fastener tasks
• Mechanical assembly in workshops and production settings
• General repair and household maintenance requiring 19 mm hex access

Key specifications

• Drive size: 1/2 inch
• Socket size: 19 mm
• Point profile: 6-point (hex)
• Compatibility: for use with 1/2" drive ratchets and torque tools
• Intended use: fastening and loosening 19 mm hex nuts and bolts

How to use

Select the 19 mm Hartsson socket and attach it securely to a compatible 1/2" drive ratchet or torque wrench. Place the socket over the hex fastener ensuring full contact on the flats, then apply controlled turning force in the required direction. When applying specified torque, use a calibrated torque tool and follow manufacturer torque settings for the fastener. After use, detach the socket and store it in an appropriate tool holder to protect the drive interface and internal profile.

Usage recommendations

Use the socket only with compatible 1/2" drive tools and avoid applying impact-style forces unless the socket is explicitly rated for impact use. Inspect the socket and fastener surfaces for damage before operation and follow torque specifications to prevent over-tightening or fastener failure.
