• Enhanced corrosion resistance from cadmium plating, extending service life in harsh industrial environments.
• Exceptional durability due to Rockwell C45 hardness, resisting wear and deformation under high stress.
• Secure, non-slip engagement with the cup point design, preventing component movement in dynamic applications.
• Easy installation and removal using a standard 3/32" hex key, reducing assembly time and tooling requirements.
• Reliable performance in fine-thread applications with 10-32 UNF right-hand threads for improved adjustment accuracy.
• Compliance with stringent MS51964-49 specifications, ensuring consistent quality and interchangeability.

Professional Applications & Engineering Value

This 10-32 UNF Class 3A set screw is engineered to address common challenges in precision machinery, automotive, and aerospace applications where vibration loosening and component misalignment are critical concerns. The cadmium-plated alloy steel construction provides excellent corrosion resistance, reducing maintenance needs in humid or chemically aggressive settings. Its cup point design bites securely into shafts and collars, maintaining positional accuracy without slipping, while the fine thread spacing allows for precise adjustments in tight-tolerance assemblies. The headless and hex drive configuration ensures a flush fit in confined spaces, making it ideal for permanent or semi-permanent fastening in demanding industrial environments.
