Socket 1/2" 6-point 17mm Unior U600858

Unior 1/2" 6-point 17mm socket U600858 is a hand tool socket engineered for use with 1/2-inch drive ratchets, torque wrenches and extensions. The 6-point internal profile engages hexagonal fasteners to reduce rounding and provide direct contact on flat surfaces of bolts and nuts. The 17mm size matches metric fasteners commonly found on cars, motorcycles and general machinery. Constructed for workshop and field use, the socket is intended to deliver reliable torque transfer and resist deformation under typical maintenance loads.

Advantages

The 6-point design minimises slipping and protects fastener corners compared with 12-point variants, improving contact and torque transmission. Manufactured by an established hand tool maker, the socket is made from hardened steel for durability and consistent fit. Its standard 1/2" drive interface ensures compatibility with commonly used ratchets, breaker bars and torque tools, while the 17mm diameter covers a wide range of metric applications.

Suitable for

• Automotive repairs and wheel, brake or suspension maintenance
• Mechanical assembly and disassembly of machinery with metric fasteners
• Workshop maintenance, equipment servicing and general repair tasks
• Use with 1/2" drive ratchets, extensions and torque wrenches

Key specifications

• Drive size: 1/2 inch
• Internal profile: 6-point (hex)
• Nominal size: 17 mm
• Material: heat-treated/hardened steel (tool-grade)
• Application: metric hex bolts and nuts

How to use

Select the socket that matches the nominal size of the hex fastener and fit it onto a compatible 1/2" drive ratchet, breaker bar or torque wrench. Seat the socket fully onto the fastener head to ensure full contact on the flats before applying force. Apply steady, controlled torque in the required direction; when using a torque wrench, set the specified torque value and operate according to the wrench manufacturer’s instructions. Inspect the socket and fastener surfaces periodically for wear and replace if deformation or rounding is observed.

Usage recommendations

Use the socket with appropriate hand tools rated for the intended torque. Avoid impact tools unless the socket is specifically marked for impact use. Keep sockets clean and lightly lubricated at the drive connection to prevent corrosion and maintain easy fitment. Store in a tray or rack to protect the drive end and maintain organized access.
