Professional Applications & Engineering Value
This nylon patch locking screw solves critical fastening challenges in high-vibration environments where traditional fasteners fail. The 18-8 stainless steel core provides exceptional corrosion resistance, while the permanent thread locker eliminates loosening under continuous stress. Engineers specify this fully threaded UNC screw for aerospace, automotive, and industrial equipment where sealing capabilities prevent fluid ingress and pressure loss. The combination of passivated finish and silicone O-ring creates a dual-protection system against environmental degradation, making it ideal for assemblies requiring both mechanical security and environmental sealing in demanding operating conditions.
Specification Summary & Compliance
Manufactured to Class 2A thread fit with UNC coarse threading and complete compliance with MIL-DTL-18240 specifications (including MS3212-13L, NASM3212, NASM82496). Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The screw maintains dimensional precision with 6-32 thread size, 3/8" length, and standardized pan head profile for consistent performance across industrial applications.
