Buying Guide
Common Questions
What information do you need to quote this series?
Share the standard, thread size, length, material, grade, finish and quantity. For non-standard parts, a drawing or sample helps us confirm production details faster.
Can you make sizes or materials not listed here?
Yes. We manufacture to drawing and to sample. Send your specification through the RFQ form and we will confirm feasibility, MOQ and lead time.
What inspection and material documents can you provide?
Material test certificates, dimensional inspection reports and coating reports are available on request, depending on the material and finish of your order.
What is the MOQ, and can I get samples first?
MOQ depends on size, material and finish — standard catalog sizes start lower, and custom parts are quoted per drawing. Samples are available for most standard items; mention sampling when you send the RFQ and we will confirm.
How long does production and delivery take?
Lead time is confirmed per order with your quotation. Coated and custom parts need additional production and surface-treatment time. Share your target delivery date in the RFQ and we will confirm whether we can meet it before you commit.
Can't find the exact spec?
We manufacture standard and custom fasteners to order. Tell us the size, material, grade, finish and quantity — or send your drawing — and we will confirm MOQ and lead time.
