Socket Jonnesway 1/2" 12-point 17 mm S04H4917

Jonnesway 1/2" 12-point 17 mm socket (model S04H4917) is a hand tool designed for use with 1/2-inch drives, ratchets and extensions. The 12-point internal profile provides multiple engagement angles, allowing easier access to fasteners in restricted spaces while maintaining secure contact on many bolt head shapes. The socket is intended for automotive maintenance, mechanical repair and general workshop tasks where a compact, versatile 17 mm drive accessory is required.

Advantages

The 12-point geometry reduces the need to reposition the tool when working in tight areas and improves alignment with hexagonal and some rounded fasteners. Designed for compatibility with standard 1/2-inch drive tools, the socket offers straightforward interchangeability with common ratchets and extensions. Manufactured by Jonnesway, the product emphasizes practical fit and the convenience of a mid-size 17 mm option for a wide range of repair and maintenance jobs.

Suitable for

• Automotive repair and maintenance, including wheel and engine work
• Mechanical and industrial equipment servicing
• General workshop tasks and home mechanical projects
• Working in confined or angled access situations where repositioning is difficult

Key specifications

• Drive size: 1/2-inch compatible
• Socket opening: 12-point internal profile
• Nominal size: 17 mm
• Intended use: manual operation with ratchet or extension
• Typical applications: automotive, mechanical repair, workshop maintenance

How to use

Select the 17 mm socket and attach it securely to a 1/2-inch drive ratchet or extension. Engage the socket squarely onto the fastener, ensuring the 12-point profile seats fully before applying torque. For stubborn or rusted fasteners, use controlled, steady force and consider applying penetrating lubricant first. Avoid using impact tools with sockets not specified for impact use; check tool compatibility before applying high torque.

Usage recommendations

Use the socket with properly sized 1/2-inch drive ratchets or extensions and avoid excessive side loading. Regularly inspect for wear or deformation and replace if the internal profile shows rounding. For best results in tight spaces, pair the socket with a low-profile extension or universal joint designed for 1/2-inch drives.
