What Buyers Should Know Before Sourcing DIN 7380 Button Head Socket Screws
DIN 7380 button head socket screws are not only a small hardware item. For wholesale buyers, they are stock-controlled parts that must be consistent in size, finish, drive quality, packing, and labeling. A wrong head height, weak socket, mixed thread pitch, or unclear carton label can create real sorting cost downstream.
Before placing a wholesale order, confirm whether the buyer accepts DIN 7380, DIN 7380-1, or ISO 7380-1. If the screws will be resold to machinery, electrical, or OEM customers, the standard and grade should be written clearly on the quotation, invoice, packing list, and carton label. XZ Fastener also provides a broader range of standard fasteners for buyers combining screws, bolts, nuts, washers, and threaded items in one procurement plan.
Common Purchasing Descriptions
Wholesale purchasing descriptions should be short enough for daily trade but complete enough for production, inspection, and warehouse control.
| Incomplete Description | Better Wholesale Description |
|---|---|
| M6 button head screws | DIN 7380 button head socket screw, M6 x 20, Class 10.9, black oxide, 50,000 pcs, bulk carton packing |
| Stainless socket screw | ISO 7380-1 button head socket screw, M5 x 16, A2-70 stainless steel, passivated, small box packing |
| Zinc plated button screw | DIN 7380, M8 x 25, carbon steel Class 10.9, zinc plated, hex socket drive, labeled by size and batch |
| Special low head screw | Button head socket screw made to drawing, specified material, finish, tolerance, sample approval, and buyer label |
Many distributors purchase DIN 7380 screws together with 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. These items should be listed separately because the standards, head forms, grades, finishes, and packing needs are different.

Material and Grade Explanation
Carbon Steel and Alloy Steel
Carbon steel and alloy steel DIN 7380 screws are commonly used for machinery covers, brackets, fixtures, and industrial assemblies. Class 10.9 is a frequent request because socket screws often require higher strength than light-duty machine screws.
For load-sensitive applications, buyers should compare the screw requirement with related high-strength fasteners. A button head screw may not be the correct substitute for a socket head cap screw or a hex bolt in every joint.
Stainless Steel
A2 stainless steel is used for general corrosion resistance and clean appearance. A4 stainless steel is more suitable for coastal, marine, chemical, or high-humidity environments. For wholesale stock, buyers should separate A2 and A4 clearly in packaging and labels.
Stainless socket screws may require anti-galling consideration during installation, especially where repeated assembly or high-speed tools are used.
Surface Finish Selection Guide
Finish selection should match the end market. A distributor supplying indoor machinery customers may choose black oxide or zinc plating. A buyer serving outdoor equipment customers may need stronger corrosion protection.
| Finish | Suitable Wholesale Use | Buyer Note |
|---|---|---|
| أكسيد أسود | Machinery, tooling, indoor equipment, visible assemblies | Good dark appearance; limited corrosion resistance unless protected by oil or controlled storage. |
| Zinc plated | General industrial stock and light corrosion protection | Confirm color, salt spray expectation, and hydrogen embrittlement control where applicable. |
| Zinc flake | Higher corrosion resistance with controlled coating thickness | Useful when thread fit and corrosion resistance must be balanced. |
| Nickel plated | Appearance-focused equipment and selected hardware lines | Check application environment and mating material before approval. |
| Stainless passivation | A2 or A4 stainless steel screws | Recommended when corrosion resistance and clean surface condition are important. |
For outdoor or corrosion-sensitive orders, review available coated fasteners before confirming the final purchase list.
Manufacturing and Quality Control
Wholesale buyers need stable repeat supply. DIN 7380 button head socket screws should be controlled through material verification, forming, socket shaping, thread production, heat treatment where required, coating, inspection, and packing.
Material grade, wire or bar diameter, heat number, and batch separation should be confirmed before production.
Head diameter, head height, socket size, thread pitch, thread length, and overall length should be checked against the standard or drawing.
Carton labels, package quantity, net weight, gross weight, pallet marks, and batch information should match the packing list.
For non-standard head dimensions, special materials, modified thread length, or private-label packing, XZ Fastener can discuss custom fasteners according to drawings, samples, or technical requirements.
تطبيقات
DIN 7380 button head socket screws are used in wholesale channels because they serve many industrial and commercial assembly needs. The main value is the low rounded head, internal drive, and clean finished appearance.
| Application Area | Why DIN 7380 Is Used | Selection Reminder |
|---|---|---|
| Machinery guards and covers | Low rounded head reduces protrusion and improves surface appearance | Confirm vibration conditions and tightening method. |
| Electrical cabinets and control panels | Clean exterior surface with socket drive installation | Choose finish according to indoor or outdoor exposure. |
| Metal brackets and frames | Useful where external wrench clearance is limited | Check load condition before replacing other screw or bolt types. |
| Furniture and display hardware | Rounded head suits exposed fastening positions | Control finish consistency and head appearance by batch. |
| Distributor stock programs | Common metric sizes can support repeat customer demand | Use clear labels by size, finish, material, and batch. |
If the wholesale order includes special kits or assembly-specific hardware, the customized service process can help define drawings, samples, packing, and inspection requirements before production.
