Русский ISO 7380-2 button head flange screws exporter
XZ Fastener exports ISO 7380-2 button head flange screws for buyers who need a low-profile rounded head, integrated bearing flange, stable hex socket drive, and export-ready packing. These metric button head screws with flange are used in machinery covers, guards, brackets, housings, automation equipment, and visible mounting points where load distribution and clean appearance are both important. Alloy steel, carbon steel, and stainless steel options can be supplied with property class, thread length, surface finish, carton labels, pallet marks, and inspection documents according to order requirement.
Quick Specs
What Buyers Should Know Before Sourcing ISO 7380-2 Button Head Flange Screws
ISO 7380-2 button head flange screws have a rounded low-profile head, internal hex socket, and integrated flange under the head. The flange increases bearing area and may reduce the need for a separate washer in selected assemblies, but final use should be checked against the seating surface, clamp load, and assembly design.
Export buyers should distinguish ISO 7380-2 flange screws from ISO 7380-1 button head screws without flange. When sourcing multiple standard fasteners, a clear item list helps avoid mixed descriptions, incorrect carton labels, and receiving delays at the destination warehouse.
Export Sourcing Notes
- Confirm size, pitch, length, flange diameter, head height, and socket size.
- State material, property class, finish, coating color, and corrosion expectation.
- Provide export carton quantity, carton weight limit, pallet size, and shipping marks.
- Request inspection records, item labels, and moisture protection before shipment if required.
Common Purchasing Descriptions
International buyers may describe this item as ISO 7380-2 button head flange screws, metric button head screws with collar, hex socket button head flange screws, button head Allen flange screws, or low-profile socket screws with integrated flange. For accurate export quotation, include the full size, material, finish, quantity, packing method, delivery term, and required documents.
Many export orders combine several metric fastener groups. Along with ISO 7380-2 flange screws, buyers may also request 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. Related industrial bolts can be quoted in the same inquiry when the assembly or distribution list requires them.
Detailed Specifications Table
| عنصر | Typical Requirement | Export Procurement Notes |
|---|---|---|
| قياسي | ISO 7380-2 | Confirm the required standard and drawing if flange dimensions or head profile are critical. |
| نطاق القطر | Common metric sizes such as M3 to M16 | Other sizes can be reviewed according to order requirement and production availability. |
| Thread | Metric coarse thread, selected fine thread options | State pitch and thread length clearly, especially for non-standard or drawing-based orders. |
| Head and Flange | Rounded button head with integrated flange | Confirm head diameter, head height, flange diameter, flange thickness, and bearing surface needs. |
| Drive | Internal hex socket | Socket depth, socket concentricity, and tool fit are important for repeated assembly work. |
| مادة | Alloy steel, carbon steel, stainless steel A2/A4 | Material should match strength, corrosion, and destination market requirements. |
| إنهاء السطح | Black oxide, zinc plated, nickel plated, plain, passivated stainless | Finish selection should match environment, appearance, and transport storage conditions. |
| Export Packing | Small boxes, inner cartons, export cartons, pallet packing | Buyer item labels, barcode labels, pallet marks, and shipping marks are available upon request. |
For modified flange diameter, special head height, non-standard length, or drawing-based export items, XZ Fastener can review custom fasteners according to drawings and order requirement.
Material and Grade Explanation
Alloy Steel and Carbon Steel
Alloy steel and carbon steel ISO 7380-2 button head flange screws are commonly used where mechanical strength, repeat assembly performance, and cost control matter. Property classes such as 8.8 and 10.9 can be discussed according to application requirements. Heat treatment, hardness, thread accuracy, and coating should be confirmed before export packing.
Stainless Steel A2 and A4
Stainless steel A2 and A4 options are often selected for equipment panels, light outdoor use, moisture-exposed assemblies, and visible hardware. A4 stainless steel can be considered where stronger corrosion resistance is required. Passivation and clean packing can be supplied according to order requirement.
When buyers compare ISO 7380-2 flange screws with other fastener products, they should evaluate head clearance, bearing area, tool access, assembly torque, and whether a separate washer is still required by the product design.
Surface Finish Selection Guide
| Finish | Typical Use | Buyer Consideration |
|---|---|---|
| Black Oxide | Machinery, tools, fixtures, indoor assemblies | Provides dark appearance; protective oil, moisture control, and carton lining should be confirmed. |
| Zinc Plated | General industrial assemblies and distributor stock | Common for carbon steel screws; color tone and corrosion target can be discussed. |
| Nickel Plated | Visible hardware and controlled appearance applications | Useful where a brighter finish is needed; check the installation environment before selection. |
| Phosphate | Industrial components requiring oil retention | Often paired with protective oil; export packing should reduce moisture exposure during transit. |
| Plain Stainless or Passivated | Stainless assemblies and moisture-exposed equipment | Passivation can be requested for improved surface cleanliness and consistency. |
For export orders involving several finishes or matched assemblies, XZ Fastener can also quote coated fasteners according to project requirement.
Manufacturing and Quality Control
Manufacturing control for ISO 7380-2 button head flange screws should cover wire material selection, cold heading, flange forming, socket forming, thread rolling, heat treatment when applicable, surface treatment, sorting, and export packing. Important inspection points include head diameter, head height, flange diameter, flange thickness, socket depth, socket fit, thread accuracy, overall length, hardness, coating appearance, and carton label verification.
For export shipments, packing control is also important. Carton strength, moisture protection, item separation, pallet wrapping, shipping marks, and buyer label accuracy should be confirmed before loading. Buyers preparing technical files can refer to the DIN and ISO fastener standards guide when checking standard references and product descriptions.

- Automation equipment, robotics frames, and fixture systems
- Brackets, mounting plates, housings, and equipment frames
- Visible assemblies requiring a low-profile head and wider bearing area
- Maintenance kits, service parts, export distribution stock, and assembly programs
The integrated flange can help distribute load across the bearing surface, but final use should follow the assembly design and material of the clamped part. When matching components are needed, XZ Fastener can also quote related flat washers and industrial nuts for complete export purchasing lists.
