Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
- Precise, secure fastening ensured by Class 3A thread fit, minimizing backlash and maintaining tight tolerances.
- High torque application capability from the 0.050" hex drive, allowing for easy installation and removal with standard tools.
- Excellent holding power provided by the cup tip design, which bites into surfaces to prevent component slippage.
- Consistent performance in fine-thread applications due to UNF thread with fine spacing, offering better adjustment and vibration resistance.
- Durable mechanical properties with Rockwell B80 hardness, ensuring the screw withstands wear and deformation under stress.
- Compliance with industry and environmental standards, including ASME B18.3, RoHS, and REACH, for safe and reliable use in global markets.
Professional Applications & Engineering Value
This 3-56 UNF set screw is engineered to address critical challenges in precision assembly and machinery. Made from 18-8 Stainless Steel, it resists corrosion in moist or chemical-exposed settings, reducing maintenance needs. The headless design and right-hand thread allow for flush mounting in confined spaces, while the fine thread spacing and Class 3A fit provide superior grip and vibration resistance in dynamic systems like aerospace components, medical devices, and automotive assemblies. The cup tip enhances clamping force on shafts or gears, preventing rotation and ensuring operational safety. By meeting ASME B18.3 specifications, it delivers consistent quality for engineers seeking reliable industrial fasteners that minimize downtime and extend equipment life.
Specification Summary & Compliance
This set screw features a 3-56 UNF thread with Class 3A precision tolerance for accurate fit, a length of 3/32", and a 0.050" hex drive. It complies with ASME B18.3 manufacturing standards and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and suitable for international supply chains.
