Custom Fastener RFQ Checklist for Factory Bulk Orders
Identify the drawing and critical features
Include the drawing number, revision, units and required quantity. Identify critical head, thread, shoulder and washer dimensions, tolerances and mating parts. State the referenced standard or approved sample. A photo can explain appearance but cannot replace dimensional requirements.
Define material, finish and acceptance
State material, property requirements and surface treatment separately. Explain which dimensions or tests require inspection records, and whether sample approval is needed before the production batch. Agree on acceptance criteria and document requirements before manufacture; avoid leaving them until delivery.
Plan the production and delivery batches
Separate the first batch quantity from annual demand. Provide the destination, target schedule, packing requirements and any split deliveries. Confirm sample arrangements, order quantity and lead time for the specific project. These details support quotation without assuming a universal minimum order or delivery promise.
