S-92695A733 6-40 x 5/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide alloy steel construction for extended service life in harsh industrial environments
• Exceptional holding power with 90° cone point design that bites deeply into mating surfaces for secure, vibration-resistant fastening
• Precision thread engagement with Class 3A fit ensuring tight tolerances and reliable performance in critical applications
• Secure installation and removal with 1/16" hex drive that prevents tool slippage and maintains fastener integrity
• Space-saving headless design allowing flush mounting where clearance is limited without compromising strength
• Consistent mechanical performance with Rockwell C45 hardness providing optimal balance of strength and durability
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental regulations for global industrial use

Professional Applications & Engineering Value

This 6-40 UNF set screw delivers exceptional engineering value in applications requiring precise component positioning and secure fastening. The black-oxide alloy steel construction provides superior corrosion resistance, making it ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The fine UNF threads with Class 3A fit ensure minimal backlash and vibration resistance in precision equipment, while the 90° cone point creates permanent seating marks for maximum holding power against rotational forces. The headless design with 1/16" hex drive enables installation in confined spaces where traditional fasteners cannot operate, solving clearance challenges in compact assemblies without sacrificing performance or reliability.
