What Buyers Should Know Before Sourcing DIN 7380 Button Head Socket Screws
DIN 7380 button head socket screws are used when the assembly needs a rounded head, lower profile, and internal hex drive. For bulk orders, consistency matters more than a single sample. Buyers should confirm head diameter, head height, socket size, thread pitch, material grade, finish, and packaging before production starts.
Standard wording also matters. DIN 7380, DIN 7380-1, and ISO 7380-1 may be treated as related in daily trade, but engineering drawings or customer specifications may require one exact reference. For buyers managing mixed DIN and ISO fasteners, this DIN and ISO fastener standards guide helps clarify how product standards, grades, and finishes should be separated in purchase documents.
Common Purchasing Descriptions
Bulk order descriptions should be precise enough for manufacturing, inspection, packing, and export documents. A short description may be convenient, but it often leaves too much room for interpretation.
| Incomplete Description | Better Bulk Order Description |
|---|---|
| M6 button head screws | DIN 7380 button head socket screw, M6 x 20, Class 10.9, black oxide, 100,000 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 |
| Custom low head screw | Button head socket screw made to drawing, specified material, finish, tolerance, sample approval, and buyer label |
Some purchasing teams combine DIN 7380 screws 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 in one bulk order. Keep each product type on a separate line because the standard, head form, strength class, finish, and packing method are different.

Material and Grade Explanation
Carbon Steel and Alloy Steel
Carbon steel and alloy steel DIN 7380 button head socket screws are commonly selected for machinery covers, brackets, metal frames, tooling, and general industrial assemblies. Class 10.9 is often requested for carbon steel socket screws because many applications require stronger performance than light-duty machine screws.
For load-sensitive or vibration-exposed assemblies, buyers should compare the screw requirement with related high-strength fasteners. Button head geometry should be approved by the engineer where preload, fatigue, or head bearing area is critical.
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. In bulk orders, A2 and A4 should be packed and labeled separately.
Stainless steel socket screws may require anti-galling consideration during installation, especially where repeated assembly, dry threads, or high-speed tools are used.
Surface Finish Selection Guide
Surface finish affects cost, appearance, corrosion resistance, thread fit, and storage life. For bulk orders, buyers should select finish according to the final application and warehouse conditions.
| Finish | Suitable Bulk Order 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 | Outdoor equipment and higher corrosion resistance applications | Useful when corrosion protection and thread fit 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 order planning, buyers can review XZ Fastener’s coated fasteners before confirming the final finish.
Manufacturing and Quality Control
Bulk order production requires repeatability. DIN 7380 button head socket screws should be controlled through material verification, forming, socket shaping, thread production, heat treatment where required, surface finishing, inspection, and packing.
Material grade, wire or bar diameter, heat number, and batch separation should be checked before production starts.
Head diameter, head height, socket size, thread pitch, thread length, and overall length should be checked against the standard or approved drawing.
Carton labels, package quantity, net weight, gross weight, pallet marks, and batch information should match the packing list and invoice.
For special head dimensions, modified thread length, non-standard material, or private-label packaging, XZ Fastener can discuss custom fasteners according to drawings, samples, or technical requirements.
تطبيقات
DIN 7380 button head socket screws are used in bulk supply programs because they serve many industrial assembly needs. The main value is the rounded low 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. |
| OEM and distributor stock | Common metric sizes can support repeat consumption | Use clear labels by size, finish, material, and batch. |
If the bulk order includes special kits, line-side packing, or assembly-specific hardware, the customized service process can help define drawings, samples, labels, and inspection requirements before production.
