Professional Applications & Engineering Value
This 3/8"-16 UNC hex headless set screw delivers exceptional engineering value for precision assembly applications where surface protection and vibration resistance are critical. The black-oxide alloy steel construction combined with Class 3A thread fit provides superior holding power in machinery, automotive components, and precision equipment. The green nylon 6/6 plastic tip eliminates surface damage on shafts, gears, and collars while maintaining secure positioning. Engineered for right-hand thread coarse spacing, this fastener offers reliable performance in high-vibration environments where headless design is essential for space-constrained applications. The combination of material strength and protective tip technology makes it ideal for permanent installations requiring both security and surface preservation.
Specification Summary & Compliance
Manufactured to exacting Class 3A thread fit standards with UNC coarse thread specification (3/8"-16). Complies with ASME B18.3 dimensional and mechanical requirements. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards. Features precise dimensional control with 3/16" hex drive, 3/8" length, and 0.188" tip diameter. The Rockwell C28 hardness rating ensures consistent mechanical performance across industrial applications.
