Ratchet Strap Fastener Specification Example for Passenger Cars: Touring Version

This is a worked specification for ratchet strap fastener in a touring version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The touring version version exists because the duty cycle on passenger cars is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

  2. Fix the base material in writing — Semi-Metallic Compound, in this example.

Where this example applies

Programmes that run touring version most often specify this build for passenger cars. Related applications include trailer axles, scooter fleets, export programmes, off-road bikes, agricultural trailers.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

What testing is included?

Standard lots ship with dimensional and hardness reports. IATF 16949 documentation is issued with the shipment when your market requires it.

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the IATF 16949-compliant build instead of a fresh interpretation.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
