• Wide operational temperature range from -50° to 250° F, making it suitable for diverse industrial conditions without performance loss.
• High mechanical strength with Rockwell C28 hardness, resisting wear and deformation under heavy loads.
• Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to address common industrial challenges such as component slippage and corrosion in demanding environments. The headless design with a hex drive allows for flush mounting in tight spaces, ideal for machinery, automotive assemblies, and precision equipment where space is limited. The nylon 6/6 plastic tip provides a non-marring, vibration-resistant hold, preventing damage to shafts and gears while maintaining grip under dynamic loads. With its UNF fine thread and Class 3A fit, it ensures precise alignment and high clamping force, reducing the risk of loosening in high-performance applications. This screw is a reliable choice for engineers seeking durability, compliance, and ease of use in industrial set screws.
