1/4"-28 × 3/16" Knurled Cup Point Socket Set Screw – Zinc Plated, CR+3, Baked

Designed for secure fastening in mechanical and industrial applications, the 1/4"-28 × 3/16" knurled cup point socket set screw provides enhanced holding strength and reliable performance. The knurled cup point increases grip by biting into the mating surface, helping resist loosening under vibration and load. Manufactured from steel and finished with zinc plating and a CR+3 coating, this fastener offers corrosion resistance for general indoor use. A post‑plating bake process helps reduce the risk of hydrogen embrittlement, while the internal hex socket drive allows precise installation in recessed or space‑restricted assemblies. Commonly used in machinery, fixtures, equipment assemblies, and general fastening applications.
