Knurled Cup Point Socket Set Screw, Zinc CR+3 Bake (Inch)
Our Knurled Cup Point Socket Set Screws with Zinc CR+3 Bake finish are designed to deliver enhanced holding power, vibration resistance, and reliable performance in demanding mechanical applications. Manufactured from high‑strength steel, these set screws feature a knurled cup point that provides aggressive grip by biting into the mating surface, making them ideal for applications requiring maximum resistance to loosening under vibration or load.
The hex socket drive allows precise torque application in recessed or confined spaces, while the Zinc CR+3 (trivalent chromium) plating offers improved corrosion resistance and a clean, bright appearance. A post‑plating bake process is applied to reduce the risk of hydrogen embrittlement, making these set screws suitable for high‑strength and safety‑critical assemblies.
Engineered for durability and secure fastening, Zinc CR+3 Bake Knurled Cup Point Socket Set Screws are commonly used in machinery, collars, pulleys, gears, shafts, couplings, and industrial equipment exposed to vibration or dynamic loading. The knurled cup point increases surface penetration and holding strength compared to standard cup points, while the zinc coating extends service life in indoor and light‑to‑moderate outdoor environments. Available in a wide range of sizes and thread options, these set screws provide dependable performance for OEM manufacturing, maintenance, and repair operations.
