S-92313A574 5/16"-18 x 1/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Precise Class 3A thread fit ensures tighter tolerances and more secure fastening compared to standard Class 2A threads
• Enhanced gripping power from the cup tip design that bites into contact surfaces without causing excessive damage
• Secure installation and removal with 5/32" hex drive that prevents cam-out and maintains tool engagement
• Exceptional durability with Rockwell B80 hardness providing reliable performance under vibration and heavy loads
• Optimized for high-volume assembly with UNC coarse threading that enables faster installation and reduced cross-threading risks
• Headless design allows for flush mounting in confined spaces where protruding fasteners aren't feasible

Professional Applications & Engineering Value

This 316 stainless steel set screw delivers critical performance advantages in demanding applications where corrosion resistance and precision threading are paramount. The UNC coarse thread configuration provides excellent engagement in softer materials and enables rapid assembly in production environments. Engineers specify this hex headless set screw for machinery components, precision instruments, and marine equipment where the combination of Class 3A thread fit and Rockwell B80 hardness ensures maintained clamping force under vibration. The cup tip creates superior holding power on shafts and rotating elements without the surface damage associated with sharper point styles, making it ideal for positioning applications requiring periodic adjustment.

Specification Summary & Compliance

This set screw maintains precision Class 3A thread fit per UNC standards with 5/16"-18 coarse thread spacing and right-hand thread direction. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring suitability for global industrial supply chains.
