S-94115A624 3/8"-16 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating for extended service life in demanding industrial environments
• Exceptional holding power with Class 3A thread fit ensuring precise, vibration-resistant fastening in critical applications
• Non-marring surface protection through green nylon 6/6 tip that prevents damage to mating components while maintaining grip
• Wide temperature tolerance with nylon tip rated for -50° to 250°F, suitable for diverse operating conditions
• Optimized torque transmission via hex drive design allowing high installation force without head protrusion
• Enhanced mechanical strength from alloy steel construction with Rockwell C28 hardness for reliable performance under load
• Industry-standard compatibility with UNC coarse threads ensuring easy installation and interchangeability

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial assembly challenges. The headless design with hex drive provides flush mounting in confined spaces while enabling high torque application. The Class 3A UNC thread fit ensures precise engagement with mating components, reducing vibration-induced loosening in machinery, automotive, and equipment manufacturing applications. The green nylon 6/6 plastic tip offers dual benefits: preventing surface damage to expensive components while creating additional friction against rotation. With its coarse thread spacing and right-hand thread direction, this fastener enables rapid installation in high-volume production environments while maintaining secure positioning of shafts, collars, and gears.
