H&R Wheel Bolt Round Head Length

H&R wheel bolts with a round head (also called a ball seat or radius seat lug bolt) are made to secure aftermarket and OEM-style wheels to the hub. They are an alternative to stud-and-nut setups, and they are often used with wheel spacers or adapters. Each bolt is sold by part number, so choose the thread and length that match your application.

Key Features:

• Round head (radius seat) design for wheels with a matching rounded seat
• Threaded wheel bolt that replaces a factory lug bolt
• Available in several lengths and thread specifications to suit different hub and wheel setups
• Made by H&R, a German maker of suspension and wheel accessory products

Always check that the seat type, thread pitch and bolt length match your wheel and hub. Tighten to the torque the vehicle or wheel manufacturer specifies.
