Ratchet Strap Fastener Specification Example for Passenger Cars: Reinforced Build
Ratchet Strap Fastener Specification Example for Passenger Cars: Reinforced Build
This is a worked specification for ratchet strap fastener in a reinforced build 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 reinforced build 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 warranty claims traced back to a single lot.
Example specification
| Item | Ratchet Strap Fastener |
|---|---|
| Application | Passenger Cars |
| Version | Reinforced Build |
| Base material | Titanium Alloy |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | zinc plated |
| MOQ | 500 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | E-mark |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Titanium Alloy, 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
- precision stamping
- anodising
- electroplating
- heat treatment
- surface grinding
- cold forging
Where this example applies
Programmes that run reinforced build most often specify this build for passenger cars. Related applications include utility trailers, rental motorcycles, off-road bikes, export programmes, trailer axles.
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 is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. E-mark documentation is issued with the shipment when your market requires it.
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.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
