The Unifix Socket Head Cap Screws (M5 x 16) are professional-grade fasteners designed for hobbyists and industrial engineers who require reliable, high-strength connections in machinery and structural builds. Manufactured to the DIN 912 standard, these silver-finished screws offer excellent corrosion resistance and a secure fit via the socket head design, though users should ensure their project specifically requires the M5 x 16 dimensions before purchasing to avoid compatibility issues.

DIN 912 is a German standard that defines the dimensions and mechanical properties of hexagon socket head cap screws.
Yes, they feature corrosion resistance, making them suitable for most outdoor applications, though extreme marine environments may eventually require stainless steel variants.
These screws have a 5mm diameter (M5) and a 16mm threaded length.
Each box contains 500 individual pieces.
Yes, provided you use an appropriate hex bit attachment and keep the drill speed low to avoid stripping the socket.
Check the hole for debris or metal shavings; ensure the threads are properly aligned before driving.
Ensure you are using a high-quality hex key that is not worn and that it is fully seated in the screw head.
Consider using a medium-strength thread locker to secure the fastener in high-vibration applications.
To install, simply align the threaded hole and use an appropriately sized hex key (Allen wrench) to drive the screw until flush. Do not overtighten, as this may strip the threading or the internal hex socket. When working in high-moisture environments, periodically inspect the fasteners for surface oxidation. While they are corrosion-resistant, cleaning them with a dry cloth after heavy exposure to contaminants will extend their service life. Always verify thread pitch compatibility with your existing holes before insertion.
