Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers critical engineering value in food processing, pharmaceutical, and sanitary applications where contamination control is paramount. The combination of EHEDG certification and FDA compliance (21 CFR 177.2600) validates its suitability for direct food contact zones. The nitrile rubber sealing element creates reliable barriers against moisture and microbial ingress at connection points, while the metal and X-ray detectable properties address food safety protocols by enabling fragment detection in processed products. The coarse UNC threading with Class 2A fit ensures rapid installation in high-volume production environments while maintaining vibration resistance. Engineered for repeated sterilization cycles, this fully threaded fastener withstands aggressive cleaning chemicals and thermal fluctuations without performance degradation.
