Professional Applications & Engineering Value
These 5-40 UNC shoulder screws are engineered to address common industrial challenges such as misalignment and vibration-induced loosening. The 18-8 stainless steel material offers excellent corrosion resistance, making them suitable for machinery, automotive, and electronic assemblies exposed to moisture or chemicals. The Class 3A thread fit ensures tight tolerances, reducing the risk of thread stripping and enhancing load distribution. Combined with a knurled head and hex drive, these screws provide secure fastening in high-stress environments, improving overall equipment durability and minimizing maintenance downtime. Their coarse thread design allows for rapid installation, streamlining production processes without compromising on strength or reliability.
Specification Summary & Compliance
This product adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. The shoulder diameter is 5/32" with tight tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"), ensuring consistent performance. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet international environmental and safety requirements for industrial fasteners.
