Socket 12-point 1/2" Jonnesway 12 mm long S04HD4712

Jonnesway 12-point socket 1/2" drive, 12 mm long S04HD4712 is a tool designed for use with 1/2" ratchets and torque wrenches. The long version provides extended reach while the 12-point internal profile enables engagement with hex fasteners in confined spaces and allows multiple indexing positions for easier alignment. This socket is intended for applications where a secure fit and additional access depth are required.

Advantages

The long 12 mm socket offers improved access to recessed fasteners compared with standard-length sockets. Its 12-point profile reduces the need for precise alignment and permits engagement on fasteners with limited rotation clearance. Machined internal faces ensure a snug fit on hex heads, and compatibility with 1/2" drive tools makes it suitable for higher torque applications. The robust construction supports repeated use in workshop and field environments.

Suitable for

• Automotive repair tasks such as engine and suspension work where fasteners are recessed
• Machinery maintenance requiring greater reach to access bolts
• General mechanical and repair tasks in workshops and garages
• Use with 1/2" torque wrenches for controlled tightening of fasteners

Key specifications

• Drive size: 1/2" compatible
• Socket profile: 12-point (double hex)
• Nominal size: 12 mm
• Length: long version for extended reach
• Intended use: designed for hex fasteners and limited-rotation environments

How to use

Select the 12 mm long socket and attach it securely to a 1/2" ratchet, breaker bar or torque wrench. Position the socket squarely onto the hex fastener, ensuring full engagement on the 12-point profile before applying torque. For tightening with specified torque, use a calibrated 1/2" torque wrench and apply gradual force until the target torque is reached. For removal, ensure steady, controlled force to avoid rounding fastener edges.

Usage recommendations

Use clean, undamaged sockets and matched drive tools to maintain fit and torque accuracy. Inspect the socket for wear or deformation before use, and avoid exceeding the recommended torque limits of your drive tool and fasteners. When accessing deep or obstructed fasteners, combine the long socket with suitable extensions or universal joints designed for 1/2" drive to preserve alignment and reduce risk of slippage.
