Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 316 stainless steel set screw delivers exceptional performance where corrosion and mechanical stress are concerns. The headless hex drive design allows installation in tight spaces, while the UNC coarse thread and Class 3A fit provide secure, repeatable fastening that resists loosening under vibration. Commonly used in machinery, automotive, and marine applications, the cup tip ensures firm contact on shafts and collars, preventing misalignment. Its Rockwell B80 hardness maintains integrity in high-stress environments, making it a reliable choice for permanent or adjustable component positioning.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise UNC 1/4"-20 coarse threads and Class 3A thread fit for tight tolerances. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Dimensions include a 5/16" length and 1/8" hex drive, manufactured from 316 stainless steel for consistent performance in regulated industrial applications.
