Professional Applications & Engineering Value
This 10-32 UNF fine thread shoulder screw with nylon patch locking technology addresses critical vibration-induced loosening in industrial machinery and precision equipment. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining 70,000 psi tensile strength for high-stress applications. The precision 1/4" shoulder diameter with tight tolerances ensures accurate alignment in assemblies, preventing component shift during operation. The permanent nylon patch thread locker eliminates the need for additional locking hardware, streamlining installation in automated manufacturing processes. Ideal for robotics, conveyor systems, and precision instruments where vibration resistance and dimensional stability are paramount.
Specification Summary & Compliance
Manufactured to Class 2A thread fit standards with UNF fine thread profile (10-32) for precise engagement. Shoulder diameter maintains -0.001" to 0" tolerance with shoulder length tolerance of 0" to 0.002" for consistent positioning. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 18-8 stainless steel material provides Rockwell B55 hardness and maintains mechanical properties across the specified temperature range.
