Professional Applications & Engineering Value
These 1/4"-20 UNC hex head screws in 18-8 stainless steel deliver critical performance in demanding sectors like machinery assembly, construction, and automotive systems. The coarse thread spacing and Class 2A thread fit minimize installation time while preventing stripping in soft or brittle substrates. With an 80,000 PSI tensile strength and Rockwell B70 hardness, they resist deformation under vibration and heavy loads, reducing maintenance needs. The fully threaded design ensures consistent clamping force across the entire 7/16" length, making them versatile for securing components in structural frameworks, electrical enclosures, and outdoor equipment where corrosion resistance is paramount.
Specification Summary & Compliance
This product adheres to ASME B18.2.1 specifications for dimensional accuracy and thread geometry, featuring a Class 2A thread fit for consistent interchangeability. The 1/4"-20 UNC coarse thread with right-hand direction and external hex drive ensures compatibility with standard tools. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances for safe use in global industrial applications.
