Threaded rods are easy to quote incorrectly when the RFQ is too short. A request like “M12 threaded rod, zinc plated, 1,000 pcs” may look clear, but it still leaves several questions open.
Is it metric coarse or fine thread? Full 1-meter rods or cut-to-length pieces? Carbon steel or stainless steel? Class 4.8, 8.8, 10.9, or ASTM grade? Zinc plated or hot-dip galvanized?
For buyers, a complete RFQ saves time and prevents wrong production.
Why Threaded Rod RFQs Need Detail
Threaded rods are used in construction, pipe supports, machinery, solar mounting, anchors, and industrial suspension systems. The same diameter can serve very different load and environment requirements.
Buyers can review the wider produits de fixation range when matching threaded rods with nuts, washers, anchors, or custom parts.
Basic RFQ Information
| Article de la demande de prix | Que préciser | Pourquoi c'est important |
|---|---|---|
| Taille | Diameter, thread pitch, and length | Controls fit and assembly |
| Norme | DIN, ISO, ASTM, ANSI, or drawing | Defines dimensional requirements |
| Note | 4.8, 8.8, 10.9, B7, A2-70, etc. | Controls strength |
| Matériel | Carbon steel, alloy steel, 304, 316 | Affects load and corrosion resistance |
| Terminer | Zingué, HDG, oxyde noir, brut | Affecte la corrosion et l'ajustement du filetage |
| Quantité | Pieces, bundles, or total length | Affects price and production planning |
| Emballage | Bundle, carton, pallet, label | Supports export and warehouse control |
Size: More Than Diameter
Threaded rod size should include diameter, pitch, and length. For metric rods, do not write only “M16.” Confirm whether it is M16 × 2.0 or a fine thread requirement.
Key Size Details
- Diamètre nominal
- Pas de filetage
- Rod length
- Cut-to-length requirement
- Tolérance de filetage si nécessaire
- Matching nut specification
If the rod must be cut to special lengths, consider fixations non standard sur mesure.
Grade and Material Selection
Grade and material should follow the load and working environment.
| Demande | Common Direction |
|---|---|
| Light suspension | Carbon steel, low or medium strength |
| Construction générale | Zinc plated or galvanized carbon steel |
| Assemblage robuste | 8.8, 10.9, or alloy steel |
| Flange or pressure equipment | ASTM A193 B7 or project-specified grade |
| Marine or chemical use | Stainless steel 316 or special material |
For load-critical applications, check attaches à haute résistance. For corrosion-sensitive projects, compare attaches en acier inoxydable et attaches enduites.
Finish: Confirm the Exact Requirement
“Galvanized” is often unclear. It may mean zinc plated or hot-dip galvanized. These finishes differ in coating thickness, corrosion resistance, appearance, and thread fit.
For hot-dip galvanized threaded rods, always confirm nut fit after coating.
Liste de contrôle finale de la demande de prix
Before sending an inquiry, include:
- Diameter, pitch, and length
- Norme ou dessin
- Matériau et qualité
- Finition superficielle
- Écrous et rondelles assortis
- Environnement applicatif
- Quantité et emballage
- Certificats ou rapports d'inspection requis
A clear threaded rod RFQ helps the supplier quote faster, choose the right process, and deliver parts that fit the job the first time.
