What Buyers Should Know Before Sourcing DIN 7380 Button Head Socket Screws
DIN 7380 button head socket screws are selected when the assembly needs a rounded low head, internal hex drive, and clean external appearance. They are often used where standard hex head bolts are too bulky or where a taller socket head cap screw is not preferred.
For export orders, the technical specification and the shipment details should be controlled together. A correct product line should state the standard, size, material, strength class, finish, quantity, packing, label content, and inspection requirements. For buyers managing several DIN and ISO items in one order, the DIN and ISO fastener standards guide is useful for confirming how product standards and mechanical grades work together.
Common Purchasing Descriptions
Clear purchasing descriptions help the exporter quote the correct part and prepare export documents without repeated clarification.

Material and Grade Explanation
Carbon Steel and Alloy Steel
Carbon steel and alloy steel DIN 7380 screws are commonly selected for industrial equipment, machinery guards, brackets, and fixture assemblies. Class 10.9 is often requested where higher mechanical strength is needed, but the actual joint design should still be reviewed.
When the assembly is load-sensitive, compare the screw requirement with related high-strength fasteners. A button head screw does not always replace a socket head cap screw or a hex bolt, especially where preload, fatigue, or tool engagement is critical.
Stainless Steel
Stainless steel DIN 7380 screws are used where corrosion resistance or a clean surface is important. A2 stainless steel is suitable for many indoor or mild outdoor applications. A4 stainless steel is better for coastal, chemical, marine, or humid environments.
Stainless steel threads can seize under high friction. Buyers should confirm mating material, installation speed, lubrication, and torque practice before approving stainless assemblies for mass production.
Surface Finish Selection Guide
Surface finish affects cost, appearance, corrosion resistance, thread fit, and customs description. It should be chosen according to the service environment and installation conditions.
| Finish | Suitable Use | Export Buyer Note |
|---|---|---|
| Óxido negro | Indoor machinery, tooling, equipment covers | Clean industrial appearance, limited corrosion protection. Oil protection may be required for shipment. |
| Zinc plated | General industrial use and light corrosion protection | Confirm color, salt spray expectation, and hydrogen embrittlement control where applicable. |
| Zinc flake | Outdoor equipment and controlled coating thickness applications | Useful when corrosion resistance and thread fit both matter. |
| Nickel plated | Appearance-focused assemblies and selected equipment parts | Check the working environment and mating material before approval. |
| Stainless passivation | Stainless steel screws for clean or corrosive environments | Specify A2 or A4 material together with passivation and packing requirements. |
For coating comparison and outdoor selection, buyers can review XZ Fastener’s coated fasteners before finalizing the purchase order.
Manufacturing and Quality Control
DIN 7380 button head socket screws are usually produced through material preparation, forming, socket forming, threading, heat treatment where required, surface finishing, inspection, and packing. For export orders, production quality and shipment control should be aligned from the beginning.
Material grade, wire or bar diameter, heat number, and production batch should be controlled before forming begins.
Head diameter, head height, socket size, thread pitch, thread length, and overall length should be checked against standard or drawing requirement.
Carton labels, quantity, net weight, gross weight, pallet marks, and packing list details should match the shipment documents.
If the product requires a special head, modified shank, non-standard thread, or unique material, XZ Fastener can discuss custom fasteners based on drawings, samples, or technical descriptions.
Aplicaciones
DIN 7380 button head socket screws are used in assemblies where a rounded head and internal drive are preferred. They are practical for many visible or semi-visible fastening positions, but the joint load and tightening method should still be checked.
| Application Area | Why Buyers Use DIN 7380 | Selection Reminder |
|---|---|---|
| Machinery guards and covers | Low rounded head reduces protrusion and improves appearance | Confirm vibration conditions and tool access. |
| Electrical cabinets and control panels | Clean outer surface and socket drive installation | Choose finish according to indoor or outdoor use. |
| Metal brackets and frames | Works well where hex head wrench clearance is limited | Check load condition before replacing other bolt types. |
| Furniture and fixture hardware | Rounded head is suitable for exposed fastening points | Keep appearance and coating consistency controlled by batch. |
| OEM production lines | Suitable for repeatable assembly with hex socket tools | Specify packing, label, barcode, and batch traceability. |
