Professional Applications & Engineering Value

This 10-24 UNC set screw with 1/4" length and black-oxide alloy steel construction addresses critical engineering challenges in precision assembly. The Class 3A thread fit provides maximum engagement strength for high-vibration environments, while the brass soft tip eliminates surface damage on shafts, gears, and collars. The hex drive headless design enables flush installation in tight spaces where protruding fasteners are unacceptable. Ideal for industrial applications requiring repeated adjustments, the Rockwell C28 hardness ensures the set screw maintains its integrity through multiple installation cycles without stripping or deformation.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision and UNC coarse thread spacing. The 10-24 thread size and 1/4" length maintain tight dimensional tolerances for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial and precision engineering applications.
