العربية ISO 7380-2 button head flange screws bulk order manufacturer
XZ Fastener manufactures ISO 7380-2 button head flange screws for bulk orders that require a low-profile rounded head, integrated bearing flange, stable hex socket drive, and consistent lot control. These metric button head screws with flange are used on machinery covers, guards, brackets, equipment housings, automation systems, and visible mounting points where load distribution and appearance both matter. Alloy steel, carbon steel, and stainless steel options can be supplied with property class, thread length, surface finish, carton quantity, pallet method, 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 buyers should still confirm seating surface, clamp load, head clearance, and tool access before placing bulk orders.
Bulk buyers should separate ISO 7380-2 flange screws from ISO 7380-1 button head screws without flange. When a project includes several standard fasteners, clear size lists and item numbers help keep production, packing, and receiving aligned.
Bulk Order Planning Notes
- Confirm size, pitch, length, flange diameter, head height, and socket size.
- Specify material, property class, coating color, finish, and corrosion expectation.
- Define first batch quantity, annual quantity plan, carton weight limit, and pallet method.
- Request item labels, inspection records, and packing separation before production if required.
Common Purchasing Descriptions
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 bulk order quotation, include the full size, material, finish, quantity, packaging style, drawing if available, and inspection expectation.
Industrial purchasing files often 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 list requires them.
Detailed Specifications Table
| Artículo | Typical Requirement | Bulk Procurement Notes |
|---|---|---|
| Estándar | ISO 7380-2 | Confirm the required standard and drawing if flange dimensions or head profile are critical. |
| Rango de diámetro | 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. |
| Material | Alloy steel, carbon steel, stainless steel A2/A4 | Material should match strength, corrosion, appearance, and assembly environment. |
| Acabado superficial | Black oxide, zinc plated, nickel plated, plain, passivated stainless | Finish selection should match environment, appearance, warehouse storage, and transport conditions. |
| Bulk Packing | Bulk cartons, inner boxes, export cartons, pallet packing | Buyer item labels, barcode labels, carton marks, and pallet plans are available upon request. |
For modified flange diameter, special head height, non-standard length, or drawing-based bulk 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 bulk production.
Stainless Steel A2 and A4
Stainless steel A2 and A4 options are often selected for equipment panels, moisture-exposed assemblies, light outdoor use, 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 comparing ISO 7380-2 flange screws with other fastener products, buyers should evaluate head clearance, bearing area, socket drive engagement, 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; storage and carton protection should reduce moisture exposure. |
| Plain Stainless or Passivated | Stainless assemblies and moisture-exposed equipment | Passivation can be requested for improved surface cleanliness and consistency. |
For bulk 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 final 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 bulk supply, lot control and packing control are important. Carton strength, item separation, buyer labels, barcode labels, pallet wrapping, carton marks, and carton weight limits should be confirmed before shipment. Buyers preparing technical files can refer to the DIN and ISO fastener standards guide when checking standard references and product descriptions.
Aplicaciones
- Machinery covers, access panels, and protective guards
- 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, distributor replenishment, and bulk 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 bulk purchasing lists.
How to Get a Faster Quotation
To receive a faster bulk order quotation, send diameter, pitch, length, material, property class, finish, quantity per size, drawing if available, packing method, label format, carton quantity, carton weight limit, pallet requirements, delivery schedule, and required inspection documents. For ISO 7380-2 screws, confirm flange diameter, flange thickness, socket size, and head appearance requirement.
For special dimensions, non-standard flange details, or buyer-specific packing, XZ Fastener’s customized service can review the request according to drawing and order requirement. Buyers can contact XZ Fastener with a size list, annual quantity plan, and packaging requirements for quotation support.
