S-90080A311 M5 Tamper Resistant Nuts

Key Features & Benefits at a Glance

• Superior tamper resistance with the specialized Tri-Groove drive, preventing unauthorized removal in high-security environments.
• Exceptional corrosion resistance due to 316 Stainless Steel construction, ideal for harsh or outdoor industrial settings.
• Reliable and precise fit with Class 6H thread tolerance, ensuring consistent performance and reducing assembly issues.
• Durable long-term performance from the robust metric coarse thread (M5 x 0.8mm), providing strong holding power in vibrating applications.
• Enhanced safety compliance by meeting RoHS 3 standards, making it suitable for regulated industries and eco-conscious projects.
• Broad compatibility with standard M5 metric coarse threaded components, simplifying sourcing and integration.
• Secure fastening in restricted spaces thanks to the compact 0.265" height, ideal for applications where profile is a concern.

Professional Applications & Engineering Value

This M5 tamper resistant nut is engineered to address critical challenges in industrial and public infrastructure where security and environmental durability are paramount. The 316 Stainless Steel material offers excellent resistance to chemicals, saltwater, and extreme weather, preventing rust and maintaining integrity in demanding applications like marine hardware, chemical processing equipment, and outdoor enclosures. The Tri-Groove drive system requires specialized tools for installation and removal, effectively deterring tampering and vandalism in public transit, utility boxes, and safety-critical machinery. With its Class 6H thread fit and metric coarse threading, it ensures a secure, vibration-resistant connection that minimizes loosening over time, providing peace of mind for engineers specifying anti-tamper fasteners in permanent or semi-permanent assemblies.
