ITP – Lug Nuts – 10mm, including boxed 10mm flat-base and tapered lug nuts in chrome and black with 14mm hex heads. These are ITP 10mm-thread lug nuts, the size used on many ATV and UTV hubs, sold in boxed sets so you can do a full machine at once. Two seat styles matter here and they are not interchangeable: a flat-base nut is made for wheels with a flat mounting face and often uses a washer-style seat, while a tapered nut centers itself in a conical seat. Using the wrong seat means the nut only touches on an edge, so it feels tight and still works loose — the most common cause of wobbling wheels and elongated stud holes on aftermarket wheels. The 14mm hex head versions let you use a standard socket in tight wheel pockets where a larger head will not fit. Chrome and black finishes let you match the look of your wheels, and replacing all of them at once keeps clamping force even across the mounting face, which protects the wheel, the studs and the hub. Torque in a star pattern to spec and re-check after the first ride — new wheels always settle. Buy the boxed set so every nut on the machine matches and wears alike.
