Impact Socket Set 1/2" for Alloy Wheels JCB 3-piece 17/19/21mm 6‑point

Impact Socket Set 1/2" for Alloy Wheels JCB 3-piece 17/19/21mm 6‑point is a compact three-socket kit designed to fit hex wheel fasteners on modern alloy wheels. With a 1/2" square drive and 6-point socket profiles in 17 mm, 19 mm and 21 mm sizes, the set is intended for use with impact wrenches, pneumatic or electric gun tools. The sockets deliver secure engagement with lug nuts and are sized for common passenger and light commercial vehicle wheel applications in workshops and mobile tyre service operations.

Advantages

The sockets feature a 6-point configuration that reduces rounding of fasteners and provides high contact area for torque transfer. Hardened steel construction and impact-rated design allow repeated use with impact tools while resisting deformation under load. The compact three-piece set covers the most frequently required wheel nut sizes, simplifying tool selection and transport. Each socket is optimized to work with 1/2" drive impact tools for reliable connection and safer operation.

Suitable for

• Removing and tightening alloy wheel lug nuts on passenger cars
• Workshop and garage tyre replacement and maintenance
• Mobile tyre service and roadside wheel changes
• Use with 1/2" drive impact wrenches, air guns or electric impact tools

Key specifications

• Socket sizes: 17 mm, 19 mm, 21 mm
• Drive: 1/2" square drive
• Point profile: 6-point (hex)
• Number of pieces: 3
• Suitability: impact-rated for use with impact wrenches and pneumatic or electric gun tools

How to use

Select the socket matching the wheel nut size and fit it onto the 1/2" drive of the impact wrench or gun. Ensure the socket fully engages the nut before applying torque. When using pneumatic or electric impact tools, follow the tool manufacturer’s operating instructions, apply controlled bursts rather than continuous full-power impacts to avoid over-tightening, and verify final torque with a calibrated torque wrench where required.

Usage recommendations

Use the set only with compatible 1/2" drive impact tools and avoid using damaged sockets. Inspect sockets for cracks or deformation before each use. For final wheel nut tightening, always confirm torque with a torque wrench to the vehicle manufacturer's specification.
