Professional Applications & Engineering Value

This precision-engineered shoulder screw addresses critical challenges in industrial assembly where vibration resistance and dimensional accuracy are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining structural integrity across a wide temperature range (-70° to 250°F). The integrated nylon patch locking feature eliminates the need for separate locking components, reducing assembly time and preventing loosening in high-vibration environments. The UNF fine thread design ensures superior clamping force distribution, while the precisely machined shoulder provides reliable bearing surfaces for rotating components, pivots, and linkages in machinery, automation systems, and precision equipment. The combination of Class 2A thread fit and controlled shoulder tolerances guarantees consistent performance in repetitive assembly operations.

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" with shoulder length tolerance of 0" to 0.002" for accurate component positioning. Manufactured to industry standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, this fastener meets stringent environmental regulations for industrial applications worldwide.
