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 precision with Class 3A fit for reliable, vibration-resistant fastening in demanding applications
- Optimal torque transmission via 5/64" hex drive, preventing tool slippage and ensuring secure installation
- Enhanced gripping power from the 118° cone point design, which bites into materials for superior axial holding strength
- High mechanical durability with Rockwell B80 hardness, resisting deformation under heavy loads
- Space-saving headless design allowing flush mounting in confined assemblies without protruding components
- Broad industrial compliance meeting ASME B18.3 standards and environmental regulations (RoHS 3 & REACH)
Professional Applications & Engineering Value
Engineered for precision industrial set screw applications, this 8-32 UNC fastener delivers critical solutions for shaft collars, gears, and pulleys where reliable positioning is paramount. The 18-8 stainless steel material combats corrosion in humid or chemical-exposed settings, while the coarse thread spacing and Class 3A thread fit ensure rapid assembly with minimal cross-threading risk. The 118° cone point concentrates pressure effectively, preventing component slippage in high-vibration machinery. Its headless, hex drive configuration enables tool access in tight spaces, making it indispensable for precision alignment systems and permanent mechanical joints across manufacturing, automotive, and aerospace sectors.
Specification Summary & Compliance
This set screw maintains UNC coarse thread specifications with 8-32 thread size and Class 3A thread fit for superior dimensional accuracy. Manufacturing adheres to ASME B18.3 standards, ensuring consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substance restrictions.
