Kurzspezifikationen
Was Käufer wissen sollten, bevor sie ISO 7380-2 Halbrundkopf-Flanschschrauben kaufen
ISO 7380-2 button head flange screws are metric hex socket screws with a rounded low-profile head and an integrated collar or flange under the head. The flange increases bearing area and can reduce the need for a separate washer in selected assemblies, but buyers should still check seating surface, clamp load, tool access, and head clearance before confirming production.
This product is often sourced with other Standardbefestigungen for machinery and equipment projects. Buyers should clearly separate ISO 7380-2 flange screws from ISO 7380-1 button head screws without flange because head geometry and installation behavior are not the same.
Hinweise zur Werksbeschaffung
- Confirm the exact ISO 7380-2 requirement, size, pitch, length, and flange dimensions.
- State whether the screw needs full thread, partial thread, or drawing-based thread length.
- Define socket depth, socket fit, head appearance, and burr control for visible assemblies.
- Provide packing, carton quantity, label format, and inspection requirements before production.
Allgemeine Einkaufsbeschreibungen
Purchasing teams may describe this item as ISO 7380-2 button head flange screws, hex socket button head screws with collar, metric button head flange screws, button head Allen flange screws, or low-profile socket screws with flange. For accurate factory quotation, the inquiry should include size, material, property class, finish, quantity, drawing if available, and packing method.
Project purchasing lists often combine several metric fastener types. Along with ISO 7380-2 flange screws, buyers may also source 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 Industrieschrauben can be quoted together when an assembly requires both socket screws and hex head fasteners.

Material- und Sortenerklärung
Legierter Stahl und Kohlenstoffstahl
Alloy steel and carbon steel ISO 7380-2 button head flange screws are commonly used when mechanical strength, repeat assembly performance, and controlled cost are important. 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 production.
Edelstahl A2 und A4
Stainless steel A2 and A4 options are suitable for equipment panels, light outdoor use, moisture-exposed assemblies, and applications where clean appearance is important. A4 stainless steel can be considered where stronger corrosion resistance is required. Passivation and clean packing can be supplied according to order requirement.
Wenn Käufer ISO 7380-2 Flanschschrauben mit anderen vergleichen Verbindungselemente, they should evaluate head clearance, bearing area, tool access, assembly torque, and whether a separate washer is still required by the design.
Leitfaden zur Auswahl der Oberflächenbeschaffenheit
| Fertig | Typische Verwendung | Überlegung des Käufers |
|---|---|---|
| schwarz oxidiert | Maschinen, Werkzeuge, Vorrichtungen, Innenmontagen | Provides dark appearance; oil protection and carton lining should be confirmed for storage. |
| verzinkt | Allgemeine Industriebaugruppen und Händlerlager | Gemeinsam für Kohlenstoffstahl-Schrauben; Farbton und Korrosionsziel können besprochen werden. |
| vernickelt | Sichtbare Hardware und kontrollierte Erscheinungsbildanwendungen | Nützlich, wenn ein helleres Finish erforderlich ist; Überprüfen Sie vor der Auswahl die Installationsumgebung. |
| Phosphat | Industriekomponenten, die eine Ölrückhaltung erfordern | Often paired with protective oil; packaging should reduce moisture exposure. |
| Rein rostfrei oder passiviert | Rostfreie Baugruppen und feuchtigkeitsexponierte Geräte | Zur Verbesserung der Oberflächenreinheit und -konsistenz kann eine Passivierung angefordert werden. |
For orders involving multiple finishes or matched assemblies, XZ Fastener can also supply Beschichtete Verbindungselemente je nach Projektanforderung.
Herstellung und Qualitätskontrolle
Factory control for ISO 7380-2 button head flange screws should cover wire material, 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, and finish appearance.
For visible assemblies, burr control, head marks, coating consistency, and packing protection are especially important. Buyers preparing technical files can refer to the Leitfaden zu den Befestigungsnormen DIN und ISO when confirming standard references and product descriptions.
Anwendungen
- Maschinenabdeckungen, Zugangsklappen und Schutzvorrichtungen
- Automatisierungsgeräte, Roboterrahmen und Vorrichtungssysteme
- Halterungen, Montageplatten, Gehäuse und Geräterahmen
- Visible assemblies where a low-profile head and wider bearing area are useful
- Maintenance kits, service parts, and factory assembly programs
The integrated flange can help distribute load across the bearing surface, but the final decision should follow the assembly design. When matching components are needed, XZ Fastener can also quote related flache Unterlegscheiben und Industrienüsse für vollständige Einkaufslisten.

Can ISO 7380-2 button head flange screws be supplied in alloy steel?
Yes. Alloy steel options can be supplied according to property class, finish, size, and order requirement. Heat treatment and hardness requirements should be confirmed before production.
Are stainless steel ISO 7380-2 flange screws available?
Stainless steel A2 and A4 options are available upon request. Buyers should provide corrosion requirements, finish expectations, and packing requirements for quotation review.
Does the flange replace a washer?
The integrated flange increases bearing area and may reduce the need for a separate washer in selected applications. However, the final decision should follow the assembly design, surface material, and load requirement.
What inspection items are important for ISO 7380-2 screws?
Common inspection items include head diameter, head height, flange diameter, flange thickness, socket depth, thread accuracy, overall length, hardness, coating appearance, and packing verification.
Can ISO 7380-2 flange screws be packed with other fasteners?
