Technical FAQ
Answers for industrial buyers.
What do you need to quote a custom fastener?
A controlled drawing with revision, material, tolerances, thread and finish, plus quantity and target price.
What information is needed for U-bolts?
Diameter, inside width and length, thread length each end, material/grade and finish per DIN 3570.
Can a sketch or photograph replace a controlled drawing?
No. A sketch can start a discussion, but geometry, tolerance, material and acceptance criteria require controlled information.
What does this page confirm?
It organizes a product-specific inquiry. Reference MOQ is 500 pcs per specification and lead time is 10–15 days for stock items or 25–30 days for production; price, certification documents and delivery are confirmed in your written quotation.
What should be stated with DIN 6921 / EN 1665?
State the exact revision, dimensions, material or grade, finish, quantity, destination and required documents. The flange form changes the bearing interface, so the buyer should state the mating surface, serration requirement and assembly context.
