Size options and color coding: 17 mm, 19 mm, and 21 mm sockets are color coded for quick size identification, making it fast to select the correct tool. Protective sleeve with spinning design: Each impact socket includes a protective sleeve that spins to prevent scuffing wheels. The sleeve stays in place while the socket rotates, protecting wheel finishes during use. Durable, quality material: Constructed from sturdy material to withstand impact and regular use, delivering reliable longterm performance. Thinwalled design for alloy wheels: Thin walls provide greater clearance and access in tight spaces around alloy wheels without compromising strength. Practical and ready for impact use: Built for impact tools, with a focus on performance, compatibility, and ease of use. The color coding and sleeve protection help reduce damage and save time in busy workshops. 23 use scenarios Routine wheel maintenance on cars with alloy wheels: Quickly identify the correct lug nut socket (17, 19, or 21 mm), reduce wheel finish risk with the protective sleeve, and complete lug nut service efficiently in tight wheel wells. Workshop tasks requiring fast sizechangeovers: In a service bay, switch between different vehicles with minimal tool search time thanks to clear color coding, while protecting rims during rotation. DIY tire changes or roadside tire service: Use the thinwalled sockets to reach recessed lug nuts on alloy wheels, with the protective sleeve minimizing potential wheel damage during wheel removal and installation.
