Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Exceptional holding power with a Class 3A thread fit for tighter tolerances and reduced risk of loosening under vibration.
- Secure, non-slip locking provided by serrations that bite into mating surfaces, preventing unintended movement.
- Deep, positive engagement from the cup point design, which concentrates force for a firm grip on shafts and collars.
- Easy installation and removal with a 3/16" hex drive, allowing for high torque application in confined spaces.
- High mechanical strength with a Rockwell B80 hardness, offering excellent durability and resistance to wear.
- Broad industrial compatibility due to UNC coarse threading, facilitating quick assembly and disassembly.
Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A set screw is engineered to address critical challenges in industrial settings, such as component slippage and corrosion-induced failure. The 18-8 stainless steel material provides inherent resistance to rust and chemicals, making it ideal for applications in manufacturing, automotive, and marine environments where exposure to moisture is common. The hex headless and cup point design ensures minimal protrusion and maximum gripping force, securely fastening pulleys, gears, and knobs onto shafts without marring surfaces. Combined with serrated locking features, it effectively counters vibrational loosening, reducing maintenance needs and enhancing operational safety. Its coarse thread spacing allows for rapid installation, streamlining assembly lines and improving productivity in high-volume B2B operations.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. It features a UNC thread with Class 3A fit for precise, high-strength fastening, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial applications without hazardous substances.
