S-95289A102 6-32 x 3/16" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide coating that protects against rust and extends service life in demanding environments
• Exceptional holding power thanks to the extended tip design that creates deeper engagement and prevents component slippage
• Precise Class 3A thread fit ensures tighter tolerances and more reliable fastening compared to standard Class 2A threads
• High-strength performance with Rockwell C45 hardness providing excellent durability under heavy loads and vibration
• Space-saving headless design allows for flush mounting in confined spaces where protruding fasteners aren't feasible
• Easy installation and removal with 1/16" hex drive that provides secure tool engagement without stripping
• Industry compliance assurance meeting ASME B18.3 specifications for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

This black oxide alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent fastening are paramount. The 6-32 UNC coarse thread configuration combined with Class 3A precision tolerance ensures secure mating with components while the extended tip penetrates deeper into the mating surface, creating permanent positioning in shafts, collars, and gears. The headless design with 1/16" hex drive provides reliable installation in space-constrained assemblies common in machinery, automotive, and manufacturing equipment. The Rockwell C45 hardness maintains structural integrity under repetitive stress, making these set screws ideal for high-vibration environments where loosening could cause equipment failure or safety hazards.
