MSW’s Take: These are the same pit sockets we used when crewing for IMSA GT teams. MSI supplies pit sockets, lug nuts, and studs to IMSA, NASCAR, SRO and many others.
- Machined from 4340 alloyed steel
- Heat treated to accommodate hardened lug nuts
- Fitted with ejection spring (can be removed)
- Equipped with set screw to secure to anvil
