• Optimized torque transmission via 0.050" hex drive, preventing tool slippage and ensuring consistent installation
• Enhanced penetration and seating with 118° cone point design, providing superior grip on shaft components
• Reliable mechanical performance backed by Rockwell C45 hardness, maintaining dimensional stability under load
• Space-saving headless design allowing flush mounting where clearance is limited
• Industry-standard compatibility with UNF fine threads for precise engagement in machinery and equipment

Professional Applications & Engineering Value

This 4-48 UNF Class 3A Black-Oxide Alloy Steel set screw delivers critical engineering solutions for precision assembly challenges. The fine thread spacing and Class 3A thread fit provide exceptional clamping force retention in vibrating environments, while the 118° cone point penetrates mating surfaces for positive rotational locking. The Black-Oxide surface treatment creates a protective barrier against oxidation and chemical exposure, making these headless set screws ideal for permanent installations in machinery, automotive components, and electronic enclosures where corrosion resistance and reliable positioning are paramount. The hex drive configuration ensures efficient installation in confined spaces without compromising torque capability.
