The Detroit Speed, Inc. racing lug nuts are high quality lug nuts machined from 1144 alloy heat treated to 36 Rockwell C steel for extra durability and also have a black performance-based fastener coating that promotes better torque values to match the studs. These 19mm lug nuts will make removal easier by allowing a smaller socket to fit between the wheel and the nut.
