Steel Piston Pin Specification Example for Agricultural Trailers: Off-Road Version

This is a worked specification for steel piston pin in a off-road 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 off-road version version exists because the duty cycle on agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.

Where this example applies

Programmes that run off-road version most often specify this build for agricultural trailers. Related applications include dealership service, municipal fleets, courier fleets, export programmes, three-wheelers.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 2.5 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

Can the specification be held on file?

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

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.

What is the minimum order quantity?

The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
