Professional Applications & Engineering Value
This 18-8 stainless steel set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and corrosion protection are critical. The Class 3A thread fit ensures precise engagement with mating components, while the extended tip design (0.198" length) provides superior contact surface area for maximum holding power in pulley systems, gear assemblies, and shaft collars. The UNF fine thread spacing allows for finer adjustments and increased clamping force compared to coarse threads, making it ideal for precision machinery, automotive components, and manufacturing equipment where vibration-induced loosening is a common concern. The headless configuration and hex drive enable flush mounting in space-constrained applications while maintaining easy installation and removal access.
Specification Summary & Compliance
This 3/8"-24 UNF set screw features precision Class 3A thread fit with exacting dimensional tolerances including tip length (-0.005" to 0") and tip diameter (-0.009" to 0") specifications. Manufactured in compliance with ASME B18.3 standards for dimensional accuracy and performance reliability. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and regulatory adherence for global industrial applications.
