Thread pitch
Measure the distance from one thread crest to the next, then match it to the hub specification.
Measure crest to crest
Engineered for strength. Designed for exact fitment.
Wheel hardware is a small component with a critical job. Every dimension works together to keep the wheel centered, clamped, and ready for the road.
Measure the distance from one thread crest to the next, then match it to the hub specification.
Measure crest to crestPrecision-machined ball and conical seats center the wheel securely without damaging the mounting surface.
Match the wheel's seat geometry
Measure from the point where the seat contacts the wheel to the end of the threaded shank.
Measure seat to tipMatch the thread, seat, and shank length to your exact wheel setup. If you are using spacers or aftermarket wheels, confirm their hardware requirements before ordering.

Use your original hardware and wheel manufacturer requirements as the source of truth.
Confirm both the nominal diameter and thread pitch. Threads that appear similar may not be compatible.
Match ball radius or conical angle to the wheel. The seat must contact the wheel evenly.
Measure from the seat to the tip. Add spacer thickness when extended hardware is required.
These basics help narrow the choice. Always verify the individual product and wheel specifications before installation.
Only when the spacer system is designed for the original hardware and provides the required thread engagement. Slip-on spacers typically require a longer bolt by approximately the spacer thickness.
A ball seat has a curved contact surface defined by its radius. A cone seat uses a straight tapered surface, commonly 60 degrees. They are not interchangeable.
The correct requirement depends on the vehicle, hub material, and bolt diameter. Follow the vehicle and wheel manufacturer specifications or ask ViVA Performance to verify the application.
Start every bolt by hand, then tighten in the recommended sequence with a calibrated torque wrench to the vehicle or wheel manufacturer specification.
