Professional Applications & Engineering Value
This stainless steel shoulder screw addresses critical alignment and durability challenges in precision machinery. The 18-8 stainless steel material provides excellent corrosion resistance, while the 3/16" shoulder length with tight tolerances ensures precise component positioning in assemblies. The 10-32 UNF fine thread with Class 2A fit maintains secure fastening under vibration, making it ideal for rotating machinery, automation equipment, and precision instruments. The hex socket knurled head design prevents tool slippage during installation, reducing assembly time and improving worker safety. These features combine to deliver reliable performance in industrial applications where alignment accuracy and long-term corrosion resistance are paramount.
Specification Summary & Compliance
This precision shoulder screw features 10-32 UNF fine threads with Class 2A thread fit for consistent engagement. The shoulder maintains 3/16" diameter with -0.004" to -0.002" tolerance and 1/8" length with ±0.005" tolerance. Manufactured from 18-8 stainless steel with Rockwell B55 hardness, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications.
