Vehicle Speedometer Tachometer Specification Example for Fleet Maintenance: Adjustable Type

This is a worked specification for vehicle speedometer tachometer in a adjustable type 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 adjustable type version exists because the duty cycle on fleet maintenance is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

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.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
