العربية DIN 960 fine thread hex bolts bulk order manufacturer
XZ Fastener manufactures DIN 960 fine thread hex bolts for bulk orders where pitch control, repeatable dimensions, and batch consistency matter more than a one-time purchase. These metric fine pitch hex bolts are used in machinery, automotive assemblies, structural brackets, and equipment where vibration, limited thread engagement, or precise adjustment must be considered. Bulk buyers can specify carbon steel, alloy steel, or stainless steel, with finishes selected according to exposure conditions. For smooth production, confirm diameter, length, pitch, strength class, coating, packing, and inspection documents before the first batch is released.

What Buyers Should Know Before Sourcing DIN 960 Fine Thread Hex Bolts
DIN 960 bolts are metric fine thread hex bolts, usually specified when joint control is more important than general-purpose fastening. In bulk production, the most common problem is not the head shape. It is the pitch. A coarse-thread bolt may look similar at receiving, but it will fail the assembly requirement once matched with the nut or tapped hole.
Before issuing a purchase order, confirm the requested pitch against the drawing and the DIN and ISO fastener standards guide. For large quantity programs, the order should also define inspection level, batch marking, packing method, and whether mating nuts or washers are supplied together.
Common Purchasing Descriptions
Bulk purchase files often include several bolt families in one program. XZ Fastener can review DIN 960 items together with related product descriptions such as DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts.
| Common Description | Bulk Order Checkpoint |
|---|---|
| DIN 960 M10 x 1.25 x 50 Class 8.8 zinc plated | Confirm fine pitch, thread length, zinc finish, and carton quantity |
| DIN 960 M16 x 1.5 x 80 Class 10.9 plain | Confirm heat treatment, head marking, hardness, and tensile requirement |
| Fine thread hex bolts with nuts and washers | Confirm matched nut pitch, washer hardness, and assembly packing |
| DIN 960 assorted size bulk order | Confirm size list, quantity per size, lot traceability, and pallet marking |
For related bulk supply, see XZ Fastener industrial bolts and standard fasteners.
Detailed Specifications Table
| Specification Item | Typical Options | Production Control Point |
|---|---|---|
| Стандарт | DIN 960 | Confirm against drawing and purchase order before tooling or batch release |
| Тип резьбы | Metric fine pitch, partial thread | Use pitch gauges and go/no-go gauges according to order requirement |
| Diameter and Length | Common metric sizes supplied according to buyer size list | Measure length under head and confirm thread length tolerance |
| Strength Class | 8.8, 10.9, 12.9; other classes on request | Control material grade, heat treatment, hardness, and tensile result |
| Материал | Carbon steel, alloy steel, stainless steel A2 or A4 | Confirm material certificate and any required chemical composition report |
| Finish | Plain, zinc plated, black oxide, hot dip galvanized, zinc flake | Check coating appearance, thickness requirement, and thread fit after finish |
| Packing | Bulk cartons, small boxes, export pallets, buyer label | Confirm carton weight, quantity per box, lot label, and pallet layout |
Material and Grade Explanation
Class 8.8 carbon steel is commonly selected for industrial assemblies that require reliable strength without moving into high-load specialty hardware. Class 10.9 and 12.9 are used where higher tensile performance is required, but these grades also need suitable nuts, washers, tightening control, and surface finish selection.
For harsh environments, stainless steel A2 or A4 may be requested. A4 stainless steel is often preferred for coastal, chemical, or wet service conditions. Buyers comparing structural or equipment joints can also review high-strength fasteners.
Surface Finish Selection Guide
| Finish | Bulk Order Use |
|---|---|
| Plain | Indoor assembly, oil protection, or parts needing later treatment |
| Zinc Plated | General corrosion protection with clean appearance |
| Black Oxide | Machinery appearance requirement, usually with oil protection |
| Hot Dip Galvanized | Outdoor exposure where thicker coating is needed |
| Zinc Flake | Controlled corrosion performance with tighter coating management |
For finish-sensitive programs, compare available coated fasteners before approving bulk production.
Manufacturing and Quality Control
In bulk manufacturing, consistency across lots is the real test. A DIN 960 bolt batch must keep the same pitch, head dimension, thread length, grade marking, finish, and packing rule from the first carton to the last pallet.
- Review drawing, standard, size list, pitch, grade, finish, and packing requirement.
- Confirm raw material and heat treatment route before mass production.
- Control forming, threading, and thread length during production checks.
- Inspect dimensions, pitch, hardness, surface finish, and nut fit after coating.
- Pack by size, lot, carton quantity, and export pallet plan.
For drawings, special lengths, head markings, or matched sets, XZ Fastener can discuss custom fasteners according to order requirement.
Приложения
DIN 960 fine thread hex bolts are used where the assembly design calls for a finer pitch, better adjustment, or stronger resistance to loosening than a common coarse-thread joint. Application approval should always follow the buyer drawing or engineering specification.
- Automotive and transport assemblies using metric fine pitch fasteners
- Machinery frames, brackets, and equipment housings
- Flange connections and tapped-hole assemblies with limited engagement
- Vibration-prone equipment where pitch selection is part of joint design
- Distributor stock programs requiring controlled labels and repeat supply
Buyers can review wider fastener products when combining DIN 960 bolts with nuts, washers, threaded rods, and other project hardware.
How to Get a Faster Quotation
A bulk order quotation is faster when the request is complete. Send one size table instead of separate messages, and identify every pitch clearly. Fine thread bolts should not be quoted from diameter and length alone.
| Information Needed | Example |
|---|---|
| Size List | M10 x 1.25 x 50, M12 x 1.25 x 60, M16 x 1.5 x 80 |
| Material and Grade | Class 8.8 carbon steel, Class 10.9 alloy steel, A4 stainless steel |
| Finish | Plain, zinc plated, black oxide, hot dip galvanized, zinc flake |
| Quantity | Pieces per size, shipment batch, or annual forecast |
| Packaging | Bulk carton, small box, palletized export packing, buyer label |
| Inspection Requirements | Dimensional report, thread gauge record, hardness test, material certificate |

Часто задаваемые вопросы
What makes DIN 960 different from standard coarse-thread hex bolts?
DIN 960 fine thread hex bolts use metric fine pitch and are generally supplied with partial thread. They are specified when the joint design requires that finer pitch. They should not be replaced by coarse-thread bolts unless the buyer approves the change.
Can XZ Fastener manufacture DIN 960 bolts for bulk orders?
Yes. DIN 960 bolts can be supplied for bulk orders according to confirmed size list, pitch, strength class, material, finish, packing, and inspection requirements.
Which strength classes are commonly used for DIN 960 bolts?
Common options include 8.8, 10.9, and 12.9 for carbon or alloy steel. Stainless steel A2 and A4 options can be supplied when corrosion resistance is the main requirement.
Can DIN 960 fine thread bolts be hot dip galvanized?
Hot dip galvanized finish can be supplied when specified, but thread fit must be checked carefully because the coating is thicker than standard zinc plating. Matching nuts should be confirmed at the same time.
What inspection items should be checked before shipment?
Typical checks include diameter, length under head, thread pitch, thread fit, head dimensions, grade marking, hardness, finish appearance, coating requirement, quantity, and packing marks.
What should buyers send for a complete quotation?
Send the DIN 960 size list, exact fine pitch, material, strength class, finish, quantity per size, packaging method, required documents, and any mating nut or washer requirement.
Prepare Your DIN 960 Bulk Order Request
For accurate production review, send your DIN 960 fine thread hex bolt size list, finish, quantity, packaging method, and inspection requirements. Include matching nuts, washers, carton labels, pallet marks, and document requirements when the order is part of a larger assembly or project supply package.
