Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Precise Class 3A thread fit for superior engagement and vibration resistance in critical assemblies.
- Extended tip design allows for deeper penetration and secure fastening in soft materials or tight spaces.
- Hex drive (5/64") compatibility enables easy installation with standard tools, reducing assembly time.
- High hardness (Rockwell B80) provides excellent wear resistance and durability under mechanical stress.
- Coarse UNC threads facilitate quick installation and reduce the risk of cross-threading in industrial applications.
- Headless, right-hand thread configuration offers a flush finish and reliable unidirectional holding power.
Professional Applications & Engineering Value
This 8-32 UNC Class 3A set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it resists oxidation and chemical exposure, making it ideal for machinery, automotive, and electronics where environmental durability is critical. The extended tip ensures maximum grip in pulleys, gears, and collars, while the hex drive allows for high-torque application without stripping. Its coarse thread design and Class 3A fit provide reliable performance in high-vibration settings, reducing maintenance needs and enhancing operational safety in precision set screw applications.
Specification Summary & Compliance
This set screw features a 1/4" length with precise dimensions: thread diameter of 0.164", tip diameter of 0.109", and tip length of 0.043" (tolerances: -0.006" to 0" for diameter, -0.005" to 0" for length). It adheres to ASME B18.3 standards for dimensional accuracy and thread specifications, including UNC coarse threads and Class 3A thread fit. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
