Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering value in applications requiring exact component alignment and vibration resistance. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining structural integrity in harsh environments. The 1-1/2" shoulder length with precise diameter control ensures accurate positioning of moving parts in machinery, reducing wear and extending equipment life. The integrated nylon patch thread locker prevents loosening under dynamic loads, making it ideal for industrial automation equipment, precision instruments, and rotating assemblies where vibration-resistant fasteners are essential. The combination of Class 2A thread fit and UNF fine threads provides superior clamping force distribution for critical connections.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit with 10-32 UNF fine thread specification, ensuring precise engagement and reliable performance. The shoulder diameter maintains tight tolerance of -0.001" to 0" for accurate component alignment. Manufactured to industry standards with Rockwell B55 hardness and 70,000 psi tensile strength, this fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring compliant components.
