Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw delivers critical performance advantages for industrial assembly where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, marine applications, and food processing machinery. The integrated flange with serrations creates a secure locking action that replaces traditional washer setups, reducing component count while preventing joint failure in high-vibration environments. With coarse UNC threading and Class 2A fit, these fully threaded screws ensure rapid assembly without compromising connection security, delivering time savings in production lines while maintaining the 100,000 psi tensile strength required for structural applications.
Specification Summary & Compliance
This hex head screw features precise 5/16"-18 UNC coarse threading with Class 2A thread fit per ASME standards, ensuring consistent engagement and interchangeability. The 1" length and fully threaded design provide maximum fastening versatility. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making these screws suitable for global industrial applications with strict material restrictions.
