What to record by part family
| Part family | Required reference | Sample review |
|---|---|---|
| Nuts, bolts and locks | Thread diameter and pitch, seat geometry, engagement, finish and tool clearance. For bolts, include under-seat length. | Compare to the mating wheel seat and stud or hub thread. For lock sets, confirm the key envelope and replacement path. |
| Hub centric rings | Wheel center bore, hub pilot diameter, pilot depth, chamfer and material. State both diameters in mm. | Measure against the wheel and hub. With clean mating parts, compare the ring OD and ID with the drawing tolerances, then dry-fit it to check that it seats below the mounting face and clears the pilot fillet. Log gauge ID and the measured dimensions against the sample revision. |
| Clip-on and adhesive weights | Flange contour or mounting surface, mass steps, retention method and finish. | For clips, assess seating on the intended rim. A clip-on option needs the matching rim flange profile. An adhesive option needs a suitable mounting surface, the specified preparation and enough clearance from the brake hardware. |
| TPMS and valve hardware | Sensor OE number and protocol or market frequency, valve bore, seal geometry and service kit contents. | Confirm sealing stack, wheel profile clearance and the intended relearn process with the installer. |
| Wheel adapters and spacers | Vehicle and wheel PCD, center bore, hub pilot, thickness, fastening interface and load requirements. | Evaluate the effect on installed offset (ET), available engagement and brake and body clearances. |
Trace each claim to the configuration
Sample ID
Record the sample ID alongside thread, seat or dimensional measurements.
Document scope
Record the issuer, dated version, part revision and target-market applicability.
Quality system
Where requested, review the site and scope on supplier IATF 16949 or ISO 9001 evidence separately from SKU-level requirements.
Test or approval
If a project includes replacement wheels, confirm whether requirements such as UNECE R124 apply to that wheel and market before asking for matching evidence.
Buyer acceptance
Capture open deviations, the person who can approve them and the conditions of release.
