ZUFEKRepeatable geometry
Define functional shoulders, bearing faces, threads and drive requirements with the mating component.
DRAWING & LOT CONTROL
Automotive Components
Custom threaded components for brackets, equipment modules and other drawing-defined automotive component assemblies.
Discuss your application
Material and surface condition
Connect final properties, finish, friction and corrosion requirements in one approved specification.
Sample and lot documentation
Agree revision control, sample approval, inspection records, lot labels and packaging before production.
Relevant fastener structures
Material options to review
Manufacturing and acceptance
Send the component drawing, interface requirements, expected batch quantities and order-specific quality documents. ZUFEK’s automotive experience includes component supply-chain projects associated with Mercedes-Benz and BMW vehicle applications.
Examples describe application requirements. Material suitability, production scope and verification are confirmed against the approved drawing.
Prepare a clearer project specification.
Complete RFQ checklist ↗Follow a complete application design
Explore a proposed assembly, the fastener choices, manufacturing review and sample validation plan. This is an illustrative design study, with no claimed customer delivery or measured performance.
Automotive module enclosure fastener design study ↗Start the automotive RFQ with the actual joint
An enclosure cover, a painted bracket and a locating interface impose different requirements. Use the rows below to prepare a component-level discussion; they are design-review examples, not evidence of a delivered or OEM-approved project.
| Application | What to specify | What to check |
|---|---|---|
| Serviceable module cover | Opening sequence, tool access, usable engagement and any captive-retention requirement. | Check removal and reassembly with the representative cover, not only the tightened screw. |
| Painted bracket | Bearing-face envelope, coating contact, permissible marking and specified tightening conditions. | Evaluate seating and coating damage; use the agreed assembly method for any functional trial. |
| Locating shoulder | Mating bore, datum relationship, axial stack and final coated dimensions. | Record dimensional acceptance separately from clamp or motion validation. |
Before sample release, agree the drawing revision, required submission documents, lot identification and change-approval responsibilities. If the programme requires PPAP, material records or special testing, identify the exact deliverables during quotation rather than assuming that an automotive label includes them.
Review the illustrative module enclosure studyTooling and sampling typically take approximately 10–15 days after technical review and confirmation. Confirm the starting milestone, sample acceptance and repeat-production schedule in the quotation.

ENGINEERING GUIDE
Designing the bearing face of a custom flange screw ↗
Match the flange bearing face to the actual supporting surface. Compare the contact footprint, finish and grip length before replacing a separate washer.
ENGINEERING GUIDEHigh-strength screw coatings and hydrogen-risk review ↗
A high-strength steel fastener needs a coating decision that considers both corrosion and hydrogen exposure throughout processing.
