S-94095A145 M8 x 20 mm ASME B18.3.6M, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with durable green nylon 6/6 tip that prevents loosening under dynamic loads
• Corrosion-resistant black-oxide finish on alloy steel for extended service life in demanding environments
• Precision Class 5g6g thread fit ensures smooth installation and reliable engagement with mating components
• Wide temperature tolerance from -50° to 250°F maintains tip integrity across industrial applications
• Hex drive compatibility with 4mm tools provides secure torque transmission during installation
• Rockwell C28 hardness rating delivers optimal balance between strength and machinability
• Headless design enables flush mounting in space-constrained assemblies

Professional Applications & Engineering Value

This M8 set screw with coarse 1.25 mm pitch threading solves critical challenges in industrial machinery and equipment assembly. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the mechanical strength needed for high-stress applications. The nylon 6/6 plastic tip creates a vibration-dampening interface that prevents back-off in rotating components, making it ideal for motor mounts, gear assemblies, and precision positioning systems. With its right-hand thread direction and 20 mm length, this fastener delivers consistent clamping force while the soft tip protects sensitive shaft surfaces from marring or damage during installation and service.
