Hexagon Socket Button Head Screw ISO 7380 M6x12 black
Black Hexagon Socket Button Head Screw M6x12 – ISO 7380
The black M6x12 hexagon socket button head screw according to ISO 7380 is a modern fastening option when you want a clean look and a lower installation height than a standard socket head cap screw. The rounded button head gives a smooth, finished appearance on visible surfaces, while the hex socket drive still allows secure tightening with an Allen key—ideal for compact builds and neat-looking assemblies. Made from high-strength steel (property class 10.9) and finished with a black zinc flake coating, it combines strong clamping performance with enhanced corrosion protection and a consistent professional black surface.
Black zinc flake coating (surface finish)
Black zinc flake coating is a non-electrolytic coating system based on zinc flakes in an inorganic/organic binder. It is widely used on fasteners because it provides reliable corrosion resistance and a durable black finish. Compared to conventional electroplated zinc, zinc flake systems are valued for their uniform coverage (including edges) and for avoiding hydrogen embrittlement risk during the coating process, making them a popular choice for high-strength fasteners in demanding environments.
Why choose a button head screw?
- Lower head height: helps when clearance is limited or when parts move close to the fastener
- Modern appearance: rounded head gives a neat, professional finish on visible surfaces
- Allen drive: reliable tightening and easy installation in tighter spaces
Typical applications
- Aluminium T-slot profile constructions and accessories
- Covers, brackets, and panels where the fastener remains visible
- Automation builds, fixtures, and compact assemblies
- Projects where you want a smoother surface with fewer sharp edges

Use with our aluminium T-slot profile connectors
Button head screws are a great match for aluminium profile systems when you want a compact head and a clean finish on brackets, plates, and accessories. Pair this M6 screw with our fastening components such as:
- T-nuts / sliding nuts / hammer nuts (depending on your slot system) for fastening into the profile groove
- Angle brackets and mounting plates where a lower head height improves clearance
- Plates and flat connectors for neat, low-profile assemblies
