العربية ISO 7380 button head socket screws bulk order manufacturer
XZ Fastener manufactures ISO 7380 button head socket screws for bulk orders where buyers need a low-profile rounded head, clean appearance, reliable hex socket drive performance, and consistent lot packing for repeat assembly or distributor programs. These metric button head screws are used in machinery, panels, guards, automation equipment, fixtures, furniture hardware, and maintenance assemblies. 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. Buyers can send drawings, size lists, target finish, head style notes, and annual quantity plans for factory review.
Quick Specs
What Buyers Should Know Before Sourcing ISO 7380 Button Head Socket Screws
ISO 7380 button head socket screws are selected when a machine or product assembly needs a rounded low-profile head, controlled appearance, and internal hex drive installation. In bulk orders, buyers should confirm diameter, pitch, length, thread coverage, socket size, head height, and seating surface before production planning. The button head profile is visually smoother than a cylindrical socket cap screw, but the drive depth and tightening method should match the assembly design.
For programs that combine socket screws with other standard fasteners, XZ Fastener can quote multiple items in one purchasing list according to order requirement.
Bulk Order Planning Points
- Confirm annual quantity plan, first batch quantity, and delivery schedule.
- Specify carton quantity, carton weight limit, pallet method, and shipping marks.
- State whether parts require full thread, partial thread, or drawing-based dimensions.
- Define inspection records, material documents, and coating requirements before production.
Common Purchasing Descriptions
Buyers may list this product as ISO 7380 button head socket screws, metric button head cap screws, low head socket screws, button head Allen screws, or hex socket button head screws. For bulk order manufacturing, the inquiry should include the exact size range, material grade, surface finish, drive requirement, packing format, and inspection expectation.
Many industrial orders include several metric fasteners in the same shipment. A purchasing file may 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 together with ISO 7380 screws. Related industrial bolts can be reviewed when the assembly requires both socket screws and hex head fasteners.
Detailed Specifications Table
| Item | Typical Requirement | Bulk Order Notes |
|---|---|---|
| Standard | ISO 7380 | Confirm whether ISO 7380-1, ISO 7380-2, or a drawing-based equivalent is required. |
| Diameter Range | Common metric sizes such as M3 to M16 | Other sizes can be checked according to production and order requirement. |
| Thread | Metric coarse thread, selected fine thread options | Pitch must be stated clearly for non-standard or fine-thread orders. |
| Length | Short and medium assembly lengths | Length is normally measured from under the head unless drawings define another method. |
| Drive | Internal hex socket | Socket depth, socket fit, and concentricity should be checked for repeated assembly use. |
| Head Style | Low-profile rounded button head | Suitable for visible covers, guards, brackets, panels, and equipment housings. |
| Material | Alloy steel, carbon steel, stainless steel A2/A4 | Material can be supplied according to mechanical strength and corrosion requirement. |
| Packing | Bulk cartons, inner boxes, export cartons, pallets | Carton quantity, pallet size, item labels, and shipping marks are available upon request. |
For modified head details, non-standard length, special thread, or drawing-based production, buyers can review XZ Fastener’s custom fasteners service and provide technical drawings for quotation.
Material and Grade Explanation
Alloy Steel and Carbon Steel
Alloy steel and carbon steel ISO 7380 button head socket screws are suitable for bulk production where strength, cost control, and repeat assembly performance are important. Property classes such as 8.8 and 10.9 can be discussed according to load requirement. Heat treatment, hardness range, thread fit, and coating choice should be confirmed before production.
Stainless Steel A2 and A4
Stainless steel A2 and A4 options are used for equipment, panels, light outdoor applications, and assemblies exposed to moisture. A4 stainless steel may be selected where stronger corrosion resistance is required. Passivation, clean packing, and item separation can be supplied according to order requirement.
When comparing ISO 7380 screws with other fastener products, buyers should evaluate head clearance, tool access, tightening method, finish appearance, and the working environment of the assembled product.
Surface Finish Selection Guide
| Finish | Typical Use | Buyer Consideration |
|---|---|---|
| Black Oxide | Machinery, fixtures, tools, indoor assemblies | Provides dark appearance; protective oil, carton lining, and storage conditions should be confirmed. |
| Zinc Plated | General industrial assembly and distributor stock | A common finish for carbon steel screws; color tone and salt spray target can be discussed. |
| Nickel Plated | Visible hardware and controlled appearance applications | Useful when a brighter surface is needed; confirm application environment before selection. |
| Phosphate | Industrial components requiring oil retention | Often paired with oil protection; packing should reduce moisture exposure during storage. |
| Plain Stainless or Passivated | Stainless steel equipment and moisture-exposed assemblies | Passivation can be requested for improved surface cleanliness and consistency. |
For mixed bulk orders involving socket screws, nuts, and coated bolts, XZ Fastener can also support coated fasteners according to project requirement.
Manufacturing and Quality Control
Bulk manufacturing control for ISO 7380 button head socket screws should cover wire material selection, cold heading, thread rolling, heat treatment when applicable, surface treatment, sorting, and final packing. Important inspection points include head diameter, head height, head radius, socket depth, socket fit, socket concentricity, thread accuracy, overall length, hardness, coating appearance, and carton labeling.
For visible installations, buyers should also check burr control, head surface marks, coating color consistency, and damage prevention during packing. The DIN and ISO fastener standards guide can help buyers organize standard references before confirming a bulk production order.
Applications
- Machine guards, access covers, and service panels
- Automation equipment, robotics frames, and fixture systems
- Instrument housings, electronic enclosures, and mounting plates
- Furniture hardware, display equipment, and visible brackets
- Maintenance kits, repair stock, and distributor replenishment programs
ISO 7380 button head socket screws are chosen when a rounded, low-profile head is preferred for appearance or clearance. Matching washers and nuts may be required for complete assembly supply; XZ Fastener also provides related flat washers and industrial nuts for combined purchasing lists.
How to Get a Faster Quotation
For a faster bulk order quotation, send a size list with diameter, pitch, length, material, property class, finish, quantity per size, expected delivery schedule, carton quantity, carton weight limit, pallet method, and shipping mark requirements. If the screws are used in visible assemblies, include appearance requirements and any limits for surface marks or burrs.
