S-92311A426 10-32 x 5/16" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life
• Exceptional holding power from the Class 3A thread fit, ensuring a precise, vibration-resistant connection
• Optimized torque transmission via the 3/32" hex drive, preventing tool slippage and head stripping
• Secure, non-slip fastening provided by the cup point tip, which bites into the shaft for permanent positioning
• Enhanced durability with a Rockwell B80 hardness rating, resisting wear and deformation under load
• Space-saving headless design allows for flush mounting in applications where clearance is limited
• Guaranteed reliability and compliance, manufactured to meet ASME B18.3 specifications and global RoHS/REACH standards

Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to solve critical challenges in industrial assembly and precision machinery. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for demanding environments like manufacturing equipment, automotive components, and outdoor applications. The fine thread spacing and Class 3A thread fit deliver a tighter, more secure fit than standard threads, significantly reducing the risk of loosening under vibration—a common failure point in dynamic systems. The headless and hex drive design ensures easy installation with standard tools while maintaining a low profile. Combined with the cup point that creates a firm bite on shafts and collars, this set screw offers reliable, permanent positioning for gears, pulleys, and other rotating parts, enhancing the overall safety and longevity of your assemblies.

Specification Summary & Compliance

This set screw features a 10-32 UNF thread with a Class 3A fit for high precision and a right-hand thread direction.
