Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and assembly inefficiency. The 400 Nickel material provides excellent resistance to oxidation and chemical exposure, making it suitable for applications in marine, automotive, and electronics industries where durability is critical. Its fine thread spacing and right-hand thread direction ensure maximum clamping force and ease of installation, reducing maintenance downtime. The headless design with hex drive facilitates use in tight spaces, while the cup tip securely bites into surfaces to prevent rotational movement. Ideal for securing gears, pulleys, and collars, this screw delivers reliable performance in precision machinery and equipment.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread size with Class 3A thread fit for high precision and tight tolerances. It measures 1/4" in length with a 3/32" hex drive and cup tip design. Manufactured to meet ASME B18.3 specifications, it ensures consistent quality and performance.
