Professional Applications & Engineering Value

This M5 x 20mm zinc-plated steel screw is engineered to address common industrial challenges such as vibration loosening and environmental degradation. The coarse thread with a 0.8mm pitch provides excellent grip in softer materials or where rapid assembly is required, while the fully threaded design ensures maximum holding strength along the entire length. The rounded pan head with a slotted drive offers a low-profile, secure fit that is easy to install with standard tools, making it ideal for machinery, electrical enclosures, and automotive components. Its zinc-plated finish adds a protective layer against rust and corrosion, enhancing longevity in humid or outdoor settings. By conforming to DIN 85/ISO 1580 standards, this screw delivers reliable performance in precision engineering and industrial applications, reducing maintenance needs and downtime.
