Professional Applications & Engineering Value

This heavy-duty set screw delivers exceptional engineering value through its specialized black-oxide 12L14 steel construction and advanced swivel tip technology. The combination of UNC coarse threads with Class 2A thread fit provides superior holding power in high-vibration environments commonly found in industrial machinery, automotive assemblies, and precision equipment. The removable swivel tip with 10° maximum angle prevents marring of delicate surfaces while maintaining consistent clamping force, solving critical alignment challenges in rotating components and adjustable mechanisms. The headless hex drive design enables flush mounting in space-constrained applications where traditional fasteners cannot be used, making it ideal for collars, couplings, and precision positioning systems requiring reliable, maintenance-friendly fastening solutions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread form (3/8"-16), this set screw maintains strict tolerance control for consistent performance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety. The black-oxide surface treatment on 12L14 steel provides additional corrosion protection while maintaining the mechanical properties required for demanding industrial applications.
