  1. Part definitionStandard or drawing revision, dimensions, thread and tolerances.
  2. Material & finishGrade, property requirements, coating and appearance acceptance.
  3. Order & inspectionQuantity, destination, target date, reports and packaging.

BUYER QUESTIONS

Sourcing custom hardware parts from China

What should I include when requesting custom hardware parts?

+

Provide the exact standard or controlled drawing, size and thread where applicable, material or property requirements, finish, quantity, delivery destination and required inspection documents. Flag any requirement you have not settled so it can be clarified before quotation.

Are the listed standards interchangeable?

+

Do not assume interchangeability from a shared product name or this navigation list. State the exact standard and edition on the RFQ, review dimensional and performance requirements, and obtain engineering approval for any proposed substitution.

How do I verify a manufacturer's product range?

+

Open the company product file and its original source. A catalogue range is a starting point: confirm the precise configuration, actual production entity, in-house and subcontracted operations, sample availability and current supporting documents.

Can I request a catalogue or sample before placing an order?

+

Yes. Select a technical-document or sample request from a manufacturer product page, or use the sourcing form below. Availability, charges and delivery terms need separate confirmation. Technical-document requests do not require an order quantity.
