Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in applications requiring exact component alignment and secure fastening. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining 70,000 psi tensile strength, making it ideal for machinery, automation systems, and precision instruments. The 1" precise shoulder length with tight tolerances ensures accurate bearing surfaces and proper component spacing, while the nylon patch thread locker prevents loosening under vibration - a critical solution for rotating equipment and moving assemblies. The 10-32 UNF fine thread with Class 2A fit offers superior engagement in thin materials and delicate components, and the hex socket drive allows for efficient installation in confined spaces common in industrial equipment design.
Specification Summary & Compliance
This precision shoulder screw features Class 2A thread fit with 10-32 UNF fine threading and precise shoulder dimensions (1" length with 0" to 0.002" tolerance). Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength, the fastener includes nylon patch thread locking technology effective from -70° to 250°F. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications and export requirements.
