Tuner Wheel Nuts / Tuner Wheel Bolts
Tuner nuts and tuner bolts, often also referred to as slimline nuts and bolts, are used when there’s not enough space in the bolt hole of a wheel to fit a standard sized wheel nut or wheel bolt.
While traditional nuts and bolts have a hexagonal top, tuner nuts and bolts most often feature a key which is inserted into them. Standard sockets and spanners will not be able to tighten or to remove a tuner nut or bolt.
