Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Exceptional holding power due to Class 3A thread fit, ensuring tight, secure fastening in precision assemblies.
- High mechanical strength from Rockwell B80 hardness, providing excellent resistance to wear and deformation.
- Easy installation and removal with a 5/64" hex drive and headless design, saving time in confined spaces.
- Secure, non-slip grip thanks to the cup tip, which digs into shafts for positive locking against rotation.
- Reliable performance under vibration and load, supported by coarse UNC threads for quick assembly and robust engagement.
- Compliance with industry standards including ASME B18.3, ensuring consistent quality and interchangeability.
Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The headless hex drive design allows for flush mounting, preventing interference in compact assemblies, while the Class 3A thread fit ensures precise, repeatable fastening with minimal backlash. The cup tip provides a biting action that securely locks collars, gears, and pulleys onto shafts, reducing the risk of loosening under dynamic loads. Ideal for precision set screws in high-vibration environments, this screw delivers reliable performance and ease of maintenance, enhancing overall equipment durability.
Specification Summary & Compliance
This set screw features a Class 3A thread fit with UNC coarse threads for consistent engagement and ease of assembly. It adheres to ASME B18.3 manufacturing specifications, ensuring dimensional accuracy and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
