Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial equipment requiring permanent positioning and shaft securing. The Class 3A thread fit eliminates backlash in precision assemblies, while the UNF fine thread configuration provides superior resistance to vibrational loosening in rotating machinery. The headless design enables flush mounting in confined spaces, and the hex drive ensures reliable installation in high-torque applications. Manufactured from hardened alloy steel with Rockwell C45 hardness, this component maintains clamping force under extreme mechanical stress, making it ideal for automotive, aerospace, and manufacturing equipment where set screw reliability directly impacts operational safety and maintenance intervals.
Specification Summary & Compliance
This precision set screw features 1/4"-28 UNF fine threads with Class 3A tolerance for exacting fit requirements. Manufacturing conforms to ASME B18.3 specifications (ASTM F912) ensuring dimensional consistency. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances per the latest SVHC listing (06/14/2023).
