Hexagon Socket Button Head Screw ISO 7380 M4x5
Hexagon Socket Button Head Screw M4x5 – ISO 7380
The M4x5 hexagon socket button head screw according to ISO 7380 is a modern fastening choice when you want a clean look and a lower installation height than a standard socket head cap screw. The rounded button head provides a smooth, finished appearance while still allowing secure tightening with an Allen key—ideal for visible assemblies and compact builds. Made from steel, property class 10.9 and zinc-plated for corrosion protection, it offers strong clamping performance for everyday industrial use.
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
