Key Features & Benefits at a Glance
- Exceptional corrosion resistance with Black-Oxide surface treatment, extending service life in demanding environments.
- Superior thread precision with Class 3A fit and UNF fine threads, ensuring reliable, vibration-resistant fastening.
- High-strength durability from Alloy Steel and Rockwell C45 hardness, providing consistent performance under load.
- Secure, flush installation with headless hex drive design, ideal for confined spaces and smooth assemblies.
- Enhanced grip and positioning thanks to the cup tip, preventing component slippage in precision applications.
- Broad compliance with ASME B18.3, RoHS 3, and REACH, meeting strict industrial and environmental standards.
- Easy installation and removal using a standard 3/32" hex key, reducing assembly time and tooling costs.
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw is engineered to address common industrial challenges such as component misalignment, vibration loosening, and corrosion in harsh conditions. Made from Black-Oxide Alloy Steel, it offers enhanced durability and resistance to oxidation, making it suitable for machinery, automotive, and electronics assemblies. The fine thread spacing and right-hand thread direction provide superior holding power in high-stress applications, while the headless hex drive allows for flush mounting in tight spaces. Its cup tip ensures positive contact on shafts or collars, preventing rotational slip and maintaining precise positioning in industrial set screws applications, thereby reducing maintenance needs and improving overall system reliability.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and UNF thread type with fine spacing. It meets ASME B18.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity in industrial use.
