العربية DIN 961 fine thread hex bolts exporter
XZ Fastener exports DIN 961 fine thread hex bolts for overseas buyers who need full-thread metric fine pitch fasteners with clear specifications, stable packing, and export-ready documentation. These bolts are used in machinery, automotive assemblies, brackets, tapped holes, and equipment joints where the drawing requires fine pitch engagement across the full threaded length. Orders can be supplied in carbon steel, alloy steel, or stainless steel, with finishes selected according to corrosion exposure and assembly fit. Before shipment, buyers should confirm size, pitch, grade, coating, packing marks, and inspection documents.

Quick Specs
What Buyers Should Know Before Sourcing DIN 961 Fine Thread Hex Bolts
DIN 961 is a full-thread metric fine pitch hex bolt standard. It is often ordered for assemblies where the full threaded length is needed for clamping, adjustment, or engagement in a tapped component. Export buyers should not treat it as a general hex bolt description.
Before placing an order, check the size and pitch against the drawing and the DIN and ISO fastener standards guide. The export invoice, packing list, carton labels, and inspection report should use the same size description to avoid receiving and customs confusion.
Common Purchasing Descriptions
Export orders often combine DIN 961 with other metric bolt families. XZ Fastener can review purchase descriptions that include 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 | Export Order Checkpoint |
|---|---|
| DIN 961 M10 x 1.25 x 35 Class 8.8 zinc plated | Confirm full thread, fine pitch, finish, carton quantity, and label format |
| DIN 961 M12 x 1.25 x 50 Class 10.9 black oxide | Confirm heat treatment, grade marking, black finish condition, and test request |
| DIN 961 fine thread bolts with matching nuts | Confirm nut pitch, nut grade, coating compatibility, and bolt-nut fit after finish |
| DIN 961 assorted export shipment | Confirm size list, HS description, net weight, gross weight, and pallet marks |
For related supply programs, review XZ Fastener industrial bolts and standard fasteners.
Detailed Specifications Table
| Specification Item | Typical Options | Buyer Confirmation Point |
|---|---|---|
| Estándar | DIN 961 | Confirm full-thread fine pitch requirement before production and export documents |
| Tipo de hilo | Metric fine pitch, full thread | State exact pitch, such as M10 x 1.25 or M12 x 1.25 |
| Diameter and Length | Common metric sizes supplied according to order requirement | Measure length under head and confirm full threaded length |
| Strength Class | 8.8, 10.9, 12.9; other classes on request | Match bolt grade with nut grade, washer requirement, and application load |
| Material | Carbon steel, alloy steel, stainless steel A2 or A4 | Confirm material certificate and any chemical composition requirement |
| Finish | Plain, zinc plated, black oxide, hot dip galvanized, zinc flake, passivated | Check coating appearance, thickness requirement, and thread fit after finish |
| Export Packing | Bulk cartons, small boxes, palletized export packing | Confirm carton marks, pallet marks, part number, lot number, and weight data |
Material and Grade Explanation
Class 8.8 carbon steel is common for general industrial assemblies. Class 10.9 and 12.9 are selected when higher tensile performance is required, but these grades should be matched with proper nuts, washers, tightening method, and inspection documents.
Stainless steel A2 and A4 can be supplied for corrosion-resistant applications. A4 is normally preferred for wet, coastal, or chemical exposure. For higher load programs, buyers can compare XZ Fastener high-strength fasteners.
Surface Finish Selection Guide
| Finish | Export Use Case |
|---|---|
| Plain | Indoor use, oil protection, or parts requiring later surface treatment |
| Zinc Plated | General corrosion protection with clean appearance |
| Black Oxide | Machinery appearance requirement with light oil protection |
| Hot Dip Galvanized | Outdoor use where thicker coating is specified |
| Zinc Flake | Controlled corrosion performance with closer thread-fit management |
For finish-sensitive export orders, review available coated fasteners before confirming production.
Manufacturing and Quality Control
DIN 961 export orders require more than visual inspection. The bolt may look correct, but an incorrect fine pitch, poor coating control, or mismatched nut can delay receiving at the destination warehouse.
- Review drawing, standard, fine pitch, grade, material, finish, and destination packing rules.
- Confirm raw material and heat treatment before production release.
- Control head forming, full-thread rolling, length under head, and thread pitch during process inspection.
- Check hardness, dimensions, grade marking, coating appearance, and thread gauge result.
- Verify bolt-nut fit after coating when matching nuts are included.
- Prepare export packing, carton labels, pallet marks, invoice details, and packing list data.
When the order includes matching components, XZ Fastener can discuss compatible industrial nuts according to order requirement.
Aplicaciones
DIN 961 fine thread hex bolts are used where full-thread engagement and fine pitch control are required. They are suitable when the assembly drawing specifies this standard, not as a casual replacement for coarse-thread bolts.
- Machinery and equipment assemblies with tapped holes
- Automotive and transport components using metric fine pitch fasteners
- Brackets, covers, housings, and adjustment connections
- Flange and plate assemblies requiring full-thread engagement
- Distributor and project stock where exact pitch labeling is important
For broader sourcing, buyers can review XZ Fastener fastener products and related metric hardware.
How to Get a Faster Quotation
For export quotations, clear technical and packing information saves time. A complete request also reduces the chance of wrong-pitch supply, document mismatch, or carton relabeling before shipment.

Preguntas frecuentes
What is DIN 961 fine thread hex bolt used for?
DIN 961 fine thread hex bolts are used in assemblies requiring full-thread metric fine pitch engagement, including machinery, automotive parts, brackets, housings, and tapped-hole applications.
How is DIN 961 different from DIN 960?
DIN 961 is generally used for full-thread fine pitch hex bolts. DIN 960 is used for fine pitch hex bolts with a shank or partial thread. Buyers should confirm the drawing requirement before ordering.
Can XZ Fastener export DIN 961 bolts with matching nuts?
Yes. Matching fine-thread nuts can be supplied when the pitch, nut standard, nut grade, finish, and packing method are confirmed with the bolt order.
Can DIN 961 bolts be supplied with hot dip galvanized finish?
Hot dip galvanized finish can be supplied when specified, but fine thread fit must be checked carefully after coating. Matching nuts should be confirmed at the same time.
What documents are commonly requested for export orders?
Common documents include commercial invoice, packing list, material certificate, dimensional inspection report, thread gauge record, coating report when required, and other documents according to the purchase specification.
What should buyers send for a DIN 961 quotation?
Send the size list, exact fine pitch, strength class, material, finish, quantity per size, packaging method, destination requirements, and inspection documents needed before shipment.
Send Your DIN 961 Export Requirement
For accurate export review, send your DIN 961 fine thread hex bolt size list, finish, quantity, packaging method, and inspection requirements. Include matching nuts, carton labels, pallet marks, destination document requirements, and any drawing or sample details needed for confirmation.
