Anti Theft Lock Specification Example for Aftermarket Retail: Two-Piece Construction

This is a worked specification for anti theft lock in a two-piece construction 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 two-piece construction version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Carbon Fibre Composite, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • assembly line testing
  • surface grinding
  • die casting
  • rubber vulcanisation
  • anodising
  • injection moulding

Where this example applies

Programmes that run two-piece construction most often specify this build for aftermarket retail. Related applications include long-haul trucks, assembly programmes, construction equipment, agricultural trailers, passenger cars.

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

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.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.

Can the specification be held on file?

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

What testing is included?

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

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
