Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
- Exceptional thread engagement and vibration resistance provided by the Class 3A thread fit and UNF fine thread spacing.
- High-strength, reliable fastening ensured by a Rockwell B80 hardness, preventing deformation under load.
- Secure, flush installation with a headless and cup tip design, perfect for applications where a protruding head is not permissible.
- Easy installation and high torque application enabled by the 5/64" hex drive, allowing for a positive grip with standard tools.
- Guaranteed dimensional consistency and interchangeability through compliance with the ASME B18.3 standard.
- Safe for use in regulated industries as it is RoHS 3 and REACH compliant, containing no hazardous substances.
Professional Applications & Engineering Value
This 8-36 UNF set screw is engineered to solve critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it a dependable choice for applications exposed to moisture, chemicals, or outdoor elements. The headless design and cup tip provide a secure, flush fit against shafts and collars, effectively preventing axial movement and slippage in high-vibration environments like motors, gears, and pulleys. The Class 3A thread fit and UNF fine thread spacing ensure a tighter, more precise engagement than coarse threads, delivering superior holding power and resistance to loosening. This combination of a hex drive for high torque application and robust material properties makes it an essential component for demanding industrial set screw applications requiring reliability and longevity.
Specification Summary & Compliance
This set screw features a Class 3A thread fit for high precision and a UNF (Unified National Fine) 8-36 thread with a diameter of 0.164". It is manufactured to meet the dimensional requirements of ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances.
