S-91979A576 10-32 x 3/16" Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Maximum holding power and vibration resistance ensured by the Class 3A thread fit and fine UNF thread profile.
• Secure, flush mounting with a headless and hex drive design, perfect for confined spaces requiring a low-profile fastener.
• Enhanced grip and material displacement from the cup point tip, providing a permanent and tight set in the mating part.
• Precise pressure equalization via the vented feature (0.046" vent diameter), preventing pressure buildup in sensitive assemblies.
• Easy installation and removal with a standard 3/32" hex drive, compatible with common industrial tools.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, ensuring safety and sustainability.

Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to solve critical fastening challenges in demanding industrial applications. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for use in machinery, automotive components, and electronic enclosures exposed to moisture or chemicals. The Class 3A thread fit and fine thread spacing deliver superior clamping force and vibration resistance, preventing loosening in high-stress environments. The vented cup point design not only ensures a firm bite into shafts and collars but also allows for pressure relief, which is crucial in precision assemblies like optical devices or pneumatic systems. Its headless, hex drive configuration facilitates installation in tight spaces where a protruding head is not feasible, offering reliable performance in set screw applications across various engineering sectors.
