Fournisseur de boulons hexagonaux à filetage partiel DIN 931
XZ Fastener supplies DIN 931 partial thread hex bolts for industrial buyers who need reliable metric hex head bolts for machinery, steel structures, equipment frames, brackets, and maintenance stock. DIN 931 is commonly referenced with ISO 4014 and is selected when the unthreaded shank should pass through part of the clamped assembly. Grade 8.8 carbon steel hex bolts, zinc plated, black oxide, hot dip galvanized, plain, and other finishes can be supplied according to order requirement. Buyers can send size lists, finish details, quantity, packaging needs, and inspection requirements for quotation review.

What Buyers Should Know Before Sourcing DIN 931 Partial Thread Hex Bolts
DIN 931 partial thread hex bolts are different from fully threaded bolts. The plain shank can improve bearing in the clamped hole and is often preferred when the shear plane should not pass through threads. Before purchase, buyers should check grip length, thread length, nut engagement, washer selection, coating thickness, and whether the assembly truly needs partial thread or full thread.
Partial Thread Selection
DIN 931 is commonly used when the unthreaded shank should sit inside the clamped materials. If the assembly requires thread along the full bolt length, compare it with DIN 933 contre DIN 931 before changing the bill of materials.
Grip Length and Fit
Grip length matters more on DIN 931 than on DIN 933 full thread hex bolts. The selected bolt length should leave enough thread engagement for the nut without placing unnecessary threads in the shear area.

Explication du matériau et de la qualité
Carbon steel is commonly used for DIN 931 partial thread hex bolts because it can meet practical strength and cost targets for machinery and construction projects. Grade 4.8 may be enough for general fastening, while Grade 8.8 carbon steel hex bolts are often selected for stronger equipment, bracket, and steel frame assemblies. Grade 10.9 can be reviewed when higher strength is needed and the application allows it.
Grade selection should consider working load, mating material, tightening method, washer use, and surface finish. Higher grade does not automatically mean better performance in every joint. For comparison across high-strength bolt classes, see XZ Fastener’s guide to Propriétés mécaniques des boulons 8.8, 10.9 et 12.9.
Guide de sélection de finition de surface
The finish should be selected according to corrosion exposure, appearance needs, storage time, and thread-fit requirements. DIN 931 partial thread hex bolts can be supplied with common industrial coatings, and XZ Fastener can help buyers compare cost and application suitability before production.
| Terminer | Utilisation appropriée | Considération d'achat |
|---|---|---|
| Plaine | Oiled storage, temporary assembly, or applications requiring later coating | Nécessite une prévention contre la rouille pendant le stockage et le transport. |
| Zingué | Indoor machinery, light-duty construction, warehouse stock | Cleaner appearance and thinner coating; buyers purchasing full-thread items may also request zinc plated DIN 933 bolts. |
| Oxyde noir | Intérieurs de machines, assemblages huilés, exigences d’aspect noir | Limited corrosion protection unless combined with oil or additional protection; black oxide DIN 933 bolts can be matched for mixed orders. |
| Galvanisé à chaud | Outdoor steel structures, guardrails, brackets, solar mounting, exposed assemblies | Thicker zinc layer improves corrosion allowance but requires attention to thread fit and nut matching. Hot dip galvanized DIN 933 bolts may be ordered together for full-thread positions. |
| Dacromet ou Géomet | Équipements extérieurs et ensembles sensibles à la corrosion | Useful when coating uniformity and corrosion performance both matter. |
For broader finish comparison, review the guide de revêtement des fixations before confirming zinc plated, black oxide, HDG, or zinc flake requirements.
Fabrication et contrôle qualité
DIN 931 partial thread hex bolts are normally produced through wire preparation, heading or forging depending on size, shank control, thread rolling, heat treatment when required, surface finishing, inspection, and packing. Since DIN 931 includes both threaded and unthreaded areas, dimensional control is important for assembly fit.
- Head dimensions, shank diameter, total length, thread length, and chamfer checks
- Go/no-go thread gauge inspection for metric thread fit
- Essais de dureté et de traction pour Grade 8.8 ou classes supérieures sur demande
- Coating coverage, thickness, surface appearance, and thread build-up review
- Séparation des tailles, poids du carton, étiquette de palette et contrôles d'identification des lots
For mixed partial-thread and full-thread purchasing, XZ Fastener can review Boulons hexagonaux DIN 931 et DIN 933 Grade 8.8 in the same project or distributor stock inquiry.

FAQ
What is DIN 931 used for?
DIN 931 is used for partial thread metric hex head bolts. It is commonly selected for machinery, steel structures, brackets, equipment frames, and assemblies where an unthreaded shank is required through part of the clamped joint.
En quoi le DIN 931 est-il différent du DIN 933 ?
DIN 931 is partial thread, while DIN 933 is full thread. DIN 931 is often used when the shank needs to pass through the shear or grip area. DIN 933 full thread hex bolts are used when thread is needed along the full bolt length.
Can DIN 931 partial thread hex bolts be supplied in Grade 8.8?
Oui. Les boulons hexagonaux en acier au carbone Grade 8.8 sont une option courante pour les boulons à filetage partiel DIN 931. Des tests de dureté, de traction et des certificats de matériaux peuvent être fournis selon les exigences de la commande.
Which finishes are available for DIN 931 partial thread bolts?
Les finitions courantes incluent le brut, le zingué, l'oxyde noir, la galvanisation à chaud, le Dacromet et le Geomet. La finition correcte dépend de l'exposition à la corrosion, des exigences d'apparence, de la durée de stockage et des besoins en matière d'ajustement du filetage.
