Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction for extended service life in harsh environments
- Precise component positioning enabled by the 90° cone point design that bites securely into shafts and collars
- Maximum torque transmission through the 3/32" hex drive that prevents tool slippage during installation
- Exceptional thread engagement with Class 3A fit ensuring vibration resistance and reliable clamping force
- Space-saving headless design allowing flush mounting in confined assembly spaces
- Consistent mechanical performance maintained by Rockwell B80 hardness for repeated adjustments
- Regulatory compliance assurance meeting both ASME B18.3 specifications and environmental standards
Professional Applications & Engineering Value
This 10-32 UNF set screw delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The fine thread spacing combined with Class 3A thread fit creates superior holding power in precision assemblies, while the 316 Stainless Steel material withstands chemical exposure and marine environments. The headless configuration with 3/32" hex drive enables installation in tight spaces common in machinery, automotive, and aerospace applications. The 90° cone point provides positive locking action on rotating components, preventing axial movement without damaging shafts. These industrial set screws maintain integrity under dynamic loads, making them ideal for permanent fastening in high-stress environments.
Specification Summary & Compliance
This precision fastener features 10-32 UNF fine threads with Class 3A thread fit for superior dimensional accuracy. Manufacturing complies with ASME B18.3 specifications, ensuring consistent quality and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming the absence of restricted substances. The combination of right-hand thread direction, 0.19" thread diameter, and 1/2" length provides standardized compatibility across industrial applications.
