Jonnesway S04HD4716 1/2" 16 mm 12-point long socket

The Jonnesway S04HD4716 1/2" 16 mm 12-point long socket is a professional-grade hand tool engineered for mechanical repairs, automotive maintenance, and general workshop tasks. Featuring an extended reach and a reliable 1/2-inch drive, this socket provides the necessary leverage and depth to access recessed fasteners, bolts, and spark plugs located in tight or hard-to-reach spaces. Its durable construction ensures stable torque transmission and consistent performance under demanding conditions.

Advantages

The 12-point design allows for easier and faster engagement with fasteners, particularly in confined engine bays where swing room is limited. The extended depth reaches deeply seated bolts and spark plugs that standard sockets cannot access. Manufactured from robust materials, the socket withstands high torque loads typical of professional automotive and mechanical work, ensuring long-term reliability in daily workshop use.

Suitable for

• Automotive repairs and engine maintenance
• Accessing recessed fasteners and spark plugs
• Professional mechanical workshop tasks
• General assembly and disassembly work requiring a 1/2-inch drive

When it may not be suitable

This socket may not be suitable for tasks requiring drives other than 1/2-inch without the use of adapters. It is also not designed for 6-point specific high-impact applications where extreme shock loads are present.

Key specifications

• Drive size: 1/2 inch
• Socket size: 16 mm
• Profile: 12-point
• Design: Long / deep socket
• Application: Professional mechanical and automotive use

How to use

Select a compatible 1/2-inch ratchet, torque wrench, or breaker bar. Align the 12-point opening of the socket securely onto the 16 mm fastener or spark plug. Ensure the socket is fully seated to prevent slipping and potential damage to the fastener head. Apply steady and even force to tighten or loosen the component.

What to consider before purchase

• Verify that your fastener size is 16 mm
• Check that your existing tools use a 1/2-inch drive connection
• Assess whether a long, deep socket profile is required for your specific clearance needs

Usage recommendations: Regularly clean the socket after use and store it in a dry environment to prevent corrosion. Inspect the internal profile periodically for signs of wear to ensure continued safe and effective operation.
