• Fully threaded 20mm length offers maximum grip and holding power across the entire shank.
• Simple and universal installation with a standard slotted drive, compatible with common hand tools.
• Compliance with DIN 964 guarantees dimensional accuracy and interchangeability for engineering projects.

Professional Applications & Engineering Value

This M6 oval head screw is engineered to address critical challenges in industrial assembly and machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it a durable choice for applications in manufacturing, automotive, and outdoor equipment where exposure to moisture or chemicals is a concern. Its oval head with undercut profile allows it to sit flush with the material surface, preventing snagging and creating a clean, aerodynamic finish—essential for consumer products and enclosures. The coarse thread (1mm pitch) and Class 6g thread fit ensure quick, secure fastening even in softer materials or when alignment is imperfect, reducing assembly time and improving production efficiency. As a fully threaded metric fastener, it delivers consistent clamping force, which is vital for maintaining structural integrity in dynamic load conditions.
