S-94564A215 1/4"-28 x 3/8" Set Screws

Key Features & Benefits at a Glance

• Non-conductive and corrosion-resistant nylon plastic construction eliminates electrical risks and rust in sensitive applications
• Precise Class 2A thread fit ensures consistent engagement and reliable clamping force without cross-threading
• Fine UNF threading (1/4"-28) provides superior vibration resistance and improved load distribution compared to coarse threads
• Compact 1/8" hex drive enables installation in tight spaces while maintaining sufficient torque transmission
• Wide temperature tolerance (-40° to 185°F) maintains mechanical properties across diverse operating environments
• Headless flat tip design creates flush mounting and uniform surface contact for secure component positioning
• RoHS 3 compliance guarantees environmental regulatory adherence for global manufacturing requirements

Professional Applications & Engineering Value

This nylon plastic set screw delivers critical solutions for applications where metal fasteners pose contamination or conductivity concerns. The UNF fine thread configuration provides enhanced resistance to vibrational loosening in precision assemblies, while the Class 2A thread fit ensures consistent installation torque across production runs. The non-metallic composition makes it ideal for electrical insulation, food processing equipment, and chemical environments where corrosion resistance is paramount. With its flat tip design and headless profile, it enables flush mounting in adjustable components and precision fixtures. The material's inherent lubricity prevents galling when securing delicate shafts or threaded inserts, reducing assembly damage in sensitive mechanical systems.
