S-92311A550 1/4"-20 x 2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Exceptional holding power provided by Class 3A thread fit ensuring tight, secure fastening in critical applications
• Enhanced durability with Rockwell B80 hardness for reliable performance under mechanical stress
• Secure installation and removal through the 1/8" hex drive design, preventing tool slippage and damage
• Maximum grip and resistance to loosening from the cup point tip that creates deep indentations in mating surfaces
• Reliable coarse threading with UNC 1/4"-20 specification for quick assembly and disassembly in industrial settings
• Full regulatory compliance meeting ASME B18.3 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This 1/4-20 UNC set screw delivers exceptional engineering value for industrial applications requiring reliable shaft positioning and component security. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor elements. The headless design with hex drive allows for flush mounting in confined spaces while ensuring sufficient torque application during installation. The Class 3A thread fit guarantees precise engagement with mating components, preventing vibration-induced loosening in dynamic applications. The cup point tip creates permanent indentations in shafts and collars, delivering superior resistance to rotational forces in power transmission systems, automotive assemblies, and precision manufacturing equipment where positional accuracy is critical.
