Socket 12-point 1/2" 17 mm long, Jonnesway S04HD4717

Jonnesway 12-point 1/2" 17 mm long socket is a hand tool designed for fastening and loosening 17 mm nuts and bolts. Its 12-point internal profile works with both standard hex heads and some rounded fasteners, while the 1/2" drive provides compatibility with a wide range of ratchets and extension bars. The elongated body increases reach for recessed fasteners and improves access in confined engine bays, machinery assemblies, and workshop fixtures.

Advantages

The 12-point design allows quicker positioning on fasteners and reduces the need for precise alignment compared with 6-point sockets. The long length gives extra reach to access fasteners that sit deeper or behind obstacles. Constructed for workshop use, it fits standard 1/2" drive tools and is suitable for mechanic workflows where both versatility and reach are required.

Suitable for

• Automotive maintenance and repair
• Engine bay and underbody work where fasteners are recessed
• Industrial and machinery maintenance
• General workshop fastening and loosening tasks

Key specifications

• Drive size: 1/2" (12.7 mm)
• Socket profile: 12-point
• Nominal size: 17 mm
• Length: long version for extended reach
• Material: alloy steel suitable for hand tool use (workshop grade)

How to use

Attach the socket to a compatible 1/2" ratchet, breaker bar, or extension. Place the socket over the fastener and apply steady turning force, being mindful of torque limits for the fastener and the tool. Use extensions or universal joints if additional reach or an angled approach is required. Inspect the socket and fastener before use to ensure proper engagement and prevent rounding.

Usage recommendations

For best results, select the 17 mm 12-point socket when the fastener head is hex-shaped or slightly rounded and when extra reach is needed. Avoid using impact tools with sockets not specifically rated for impact use; use appropriate impact-rated sockets for pneumatic or high-torque impact applications. Store the socket in a dedicated rack or tool set to prevent damage and maintain clean engagement surfaces.
