Socket 12-point 1/2" Jonnesway 27 mm long (S04HD4727)

Jonnesway 12-point 1/2" drive socket, 27 mm long (S04HD4727) is a long-profile socket designed for use with 1/2" ratchets and breaker bars. The 12-point configuration allows more engagement positions on hexagonal fasteners, and the extended length reaches recessed nuts and bolts in tight assemblies. Constructed for workshop and field use, this socket is intended for automotive repair, machinery maintenance and general mechanical tasks where extra reach and reliable contact are required.

Advantages

The 12-point design provides improved alignment with hex fasteners, allowing easier fitment in confined spaces without rotating the tool excessively. The long profile increases access to recessed or hard-to-reach fasteners. Machined internal geometry and durable metal construction ensure consistent contact and wear resistance under repeated torque. Compatible with standard 1/2" drive tools, this socket integrates with common ratchets, extensions and breaker bars used in professional and home workshops.

Suitable for

• Automotive repair and engine work where recessed nuts require extra reach
• Machinery and equipment maintenance with limited access to fasteners
• General mechanical and assembly tasks using 1/2" drive tools

Key specifications

• Drive size: 1/2"
• Point count: 12-point engagement
• Socket size: 27 mm
• Profile: long / extended length for recessed fasteners
• Compatibility: designed for use with 1/2" ratchets, breaker bars and extensions
• Typical applications: automotive, machinery maintenance, general mechanical work

How to use

Select a 1/2" drive ratchet or breaker bar and attach the 27 mm socket onto the drive square until it locks. Position the socket over the fastener head, ensuring the 12-point recess seats evenly on the fastener. Apply steady torque through the ratchet or breaker bar, using extensions if additional reach or leverage is required. Inspect the socket and fastener seating periodically to avoid rounding edges; stop and re-seat if slippage occurs.

Usage recommendations

Use appropriate hand tools rated for the required torque and avoid impact tools unless the socket is specified as impact-rated. Keep the socket clean and free of debris, and store in a dry place to reduce corrosion. For high torque or stubborn fasteners, use an appropriate extension or breaker bar while maintaining controlled force to prevent fastener damage.
