Turner Motorsport s five years of endurance competition has taught us many things. One was that not all lug-nuts are made the same. While the standard nuts that we sell are great for daily drivers, HPDE events, and club racing, a beefier and more durable nut was needed for the 3-hour, 6-hour, and 24-hour professional endurance races. During the 24 Hours of Daytona, our tire changers made over 80 tire changes in NASCAR-style pitstops. That kind of abuse from air guns and fast work required the "next level" of lug-nut. These nuts are a high-grade steel with a zinc coating and they incorporate several innovative features -
The wheel-side of the nut has recessed threads so that the nut has to be square to engage the threads. Without the recess, it s far too easy to start the threads with the nut being crooked.
The head of the nut is rounded to help the socket find its position.
The zinc plating that we use is reasonably durable without being excessive. With too much coating, the chipped and worn coating fragments can end up in the threads, leading to all sorts of trouble. Anyone who has used nuts repeatedly knows that the coating is not going to last forever. The constant abuse from air guns will chip it all away. So why add weight and the potential for disaster with excess coating? We did away with most of the danger from that with a lighter coating that still resists the tough environment of the track.
Features:
Developed for our Grand-AM Continental race team
High grade steel to withstand the extreme abuse of air guns and race conditions
Bright yellow zinc plating to help tire changer zoom in on their target quickly and accurately
Minimal plating won t result in excess coating wearing off and gumming up the threads
19mm hex to prevent rounding off
Rounded top for fast socket engagement
Recessed threads to aid in fast nut-to-stud alignment without cross threading
We recommend using with Turner Motorsport bullet nose dry-lube wheel studs
