When buyers ask Chinese fastener suppliers for a quotation, the fastest reply usually comes from the clearest RFQ. A short message like “Please quote M12 bolts” is not enough for accurate pricing. The supplier still needs to confirm the standard, grade, material, surface finish, quantity, packaging, and shipping terms.
In fastener sourcing, unclear specifications often lead to wrong prices, repeated questions, or even wrong production. A good RFQ saves time for both sides.
Why Accurate RFQ Details Matter
Fasteners may look similar, but small details change cost and production method. An M16 bolt in class 8.8 zinc plated is not the same as an M16 bolt in class 10.9 hot-dip galvanized. Stainless steel 304 and 316 also have different price levels and corrosion performance.

Basic Information Suppliers Need
| Article de la demande de prix | Que fournir | Pourquoi c'est important |
|---|---|---|
| Type de produit | Boulon, écrou, rondelle, vis, ancrage, tige filetée | Defines the product category |
| Norme | DIN, ISO, ASTM, ANSI, JIS, or drawing | Controls dimensions and tolerance |
| Taille | Diamètre, longueur, pas de filetage | Prevents wrong specification |
| Matériel | Acier au carbone, acier inoxydable, acier allié | Affects strength and price |
| Note | 4.8, 8.8, 10.9, 12.9, A2-70, B7, etc. | Définit les performances mécaniques |
| Finition superficielle | Zinc plated, HDG, black oxide, Dacromet, plain | Affects corrosion resistance |
| Quantité | Pieces, sets, kg, or tons | Controls unit price and MOQ |
| Emballage | Bulk, small box, carton, pallet, private label | Affects cost and delivery |
When Drawings or Samples Are Needed
For Standard Fasteners
If the item follows common DIN, ISO, or ASTM standards, a clear product description may be enough. Buyers can compare attaches standards when the required part is a catalog item.
For Custom Fasteners
If the fastener has a special head, non-standard length, special thread, bend, hole, groove, or unusual material, drawings or samples are important. In this case, suppliers need dimensions, tolerances, material, grade, finish, and application details.
Pour les pièces basées sur un dessin, utilisez fixations non standard sur mesure as the correct sourcing direction.
Additional Details That Improve Quote Accuracy
Buyers should also include:
- Application ou environnement de travail
- Certificats ou rapports d'inspection requis
- Écrous et rondelles assortis
- Delivery deadline
- Destination port or country
- Trade terms such as EXW, FOB, CIF, or DDP
- Any salt spray, hardness, or tensile test requirement
For outdoor or corrosion-sensitive orders, review attaches enduites avant de confirmer la finition.
Conseil final
A precise fastener RFQ helps Chinese suppliers quote faster and more accurately. The best inquiry should answer three questions: what is the fastener, how will it be used, and what quality requirements must it meet?
Clear information at the RFQ stage prevents confusion later in production, inspection, packing, and delivery.
