Socket 1/2" 12-point Jonnesway 30 mm S04H4930

Jonnesway 1/2" 12-point socket, 30 mm (model S04H4930) is a hand tool socket designed for use with 1/2" drive ratchets and breakers. The 12-point internal geometry enables engagement with hex fasteners at multiple indexing positions, while the 30 mm opening fits medium-large metric nuts and bolts commonly found in automotive and mechanical maintenance. The socket’s chrome finish offers surface protection and easier cleaning after use, and the precision-machined internal dimensions provide a reliable fit to reduce rounding of fastener heads during tightening and loosening.

Advantages

The 12-point configuration allows quicker alignment with fasteners and works well in confined spaces where only small angular movement is possible. Compatibility with a 1/2" drive gives access to higher torque tools and standard impact breakers; the chrome-plated exterior resists corrosion and simplifies maintenance. Accurate internal sizing and a solid construction help ensure consistent torque transfer and longer service life under regular workshop conditions.

Suitable for

• Automotive repair and wheel and engine fastener maintenance
• General mechanical assembly and disassembly tasks
• Workshop and service station tool sets for medium to heavy-duty fastening
• Maintenance of agricultural and light industrial equipment

Key specifications

• Drive size: 1/2" compatible
• Point configuration: 12-point internal profile
• Socket opening: 30 mm
• Finish: chrome-plated exterior
• Primary use: manual ratchet and breaker bar operation for tightening and loosening hex fasteners

How to use

Select the 30 mm 12-point socket and attach it securely to a 1/2" drive ratchet or breaker bar. Place the socket squarely over the hex fastener, ensuring full engagement before applying torque. For initial loosening of tightly fastened bolts, use a breaker bar or apply controlled force with the ratchet; when tightening, apply steady, even torque and avoid over-torquing beyond fastener specifications. After use, wipe clean and store in a tool drawer or socket rail to protect the chrome finish.

Usage recommendations

Use with tools rated for the required torque and avoid impact tools unless the socket is explicitly specified as impact-rated. Inspect the socket and fastener for wear or damage before use, and replace the socket if signs of rounding, cracking, or severe corrosion appear.
