Onboard Diagnostic Tools Specification Example for Fleet Maintenance: Drilled and Slotted
Onboard Diagnostic Tools Specification Example for Fleet Maintenance: Drilled and Slotted
This is a worked specification for onboard diagnostic tools in a drilled and slotted 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 drilled and slotted 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 documentation that arrived after the container shipped.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Anodised Aluminium, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- robot welding
- powder coating
- ultrasonic cleaning
- CNC machining
- assembly line testing
- laser cutting
Where this example applies
Programmes that run drilled and slotted most often specify this build for fleet maintenance. Related applications include municipal fleets, camper conversions, racing teams, utility trailers, three-wheelers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 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
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.
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.
What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
