Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing long-term replacement costs.
- Maximum holding power and vibration resistance due to the Class 3A thread fit and extended tip design for a deeper, more secure grip.
- High-strength durability with a Rockwell B80 hardness, ensuring the set screw maintains its form and function under significant load.
- Efficient installation and removal using a standard 1/4" hex drive, allowing for high torque application with common tools.
- Reliable performance in right-hand coarse (UNC) threading for quick assembly and robust fastening in a wide range of industrial materials.
- Compliance with major industry standards including ASME B18.3, ensuring dimensional consistency and interchangeability.
- Environmentally safe for global supply chains by meeting RoHS 3 and REACH regulations, facilitating unrestricted international procurement.
Professional Applications & Engineering Value
This 18-8 stainless steel hex headless set screw is engineered to solve critical challenges in machinery assembly and component fixation. The extended tip (0.26" length) concentrates force to create a permanent, high-friction lock, effectively preventing shaft slippage and countering vibrational loosening in high-torque applications like motor pulleys, gears, and couplings. Its corrosion-resistant material ensures long-term reliability in demanding conditions, from outdoor equipment to processing plants, while the Class 3A UNC coarse thread provides a robust and rapid installation process. This combination of a precision right-hand thread and a hardened body makes it an indispensable component for engineers seeking a dependable, long-lasting fastening solution.
Specification Summary & Compliance
This set screw adheres to a Class 3A thread fit for superior dimensional accuracy and is manufactured to the ASME B18.3 standard. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
