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 ensured by Class 3A thread fit, providing tight, secure fastening with minimal backlash.
- High-strength durability from Rockwell B80 hardness, resisting wear and deformation under heavy loads.
- Secure, slip-resistant installation with a 1/4" hex drive, allowing high torque application without cam-out.
- Effective component locking thanks to the cup point tip, which bites into surfaces to prevent loosening from vibration.
- Precision-engineered fine threading (UNF 1/2"-20) for finer adjustment and increased tensile strength in demanding applications.
- Broad industry compliance meeting ASME B18.3 standards and environmental regulations like RoHS 3 and REACH.
Professional Applications & Engineering Value
This 18-8 stainless steel set screw is engineered to address critical challenges in industrial assembly, such as vibration-induced loosening and corrosion in demanding environments. The UNF fine thread and Class 3A thread fit provide superior clamping force and precision alignment, essential for machinery, automotive components, and precision instruments. The headless design and cup point tip ensure a flush finish and secure grip on shafts or collars, preventing axial movement without damaging the mating part. Its hex drive allows for efficient installation in confined spaces, making it a reliable choice for OEMs and maintenance teams seeking durable, high-performance set screws that uphold operational integrity.
Specification Summary & Compliance
This set screw adheres to Class 3A thread tolerance for precise fit, manufactured under ASME B18.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The product features a right-hand UNF fine thread (1/2"-20), 1" length, and 1/4" hex drive, delivering consistent performance in industrial fastening applications.
