Professional Applications & Engineering Value
This 316 stainless steel rounded head screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and mechanical reliability are paramount. The combination of UNC coarse threading and Class 3A thread fit provides superior vibration resistance and prevents loosening in high-stress applications. The passivated finish enhances the natural corrosion resistance of 316 stainless steel, making these hex drive screws ideal for chemical processing, marine environments, and food processing equipment where exposure to aggressive substances is common. The rounded button head design with standard profile offers a low-profile installation while the fully threaded 1" length ensures maximum engagement in various material thicknesses.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit and UNC coarse thread spacing (6-32 thread size). Complies with ASME B18.3 mechanical specifications and maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The screw features a 0.138" thread diameter and 1" length with complete threading, ensuring consistent performance across industrial applications.
