Baked Black Oxide with Nylon Pellet Socket Set Screw
Baked Black Oxide Cup Point Socket Set Screws with Nylon Pellet
Baked black oxide cup point socket set screws with a nylon pellet are high-performance fasteners engineered for precision, durability, and vibration-resistant locking in demanding mechanical applications. This advanced combination of cup point geometry, nylon locking pellet, and baked black oxide finish delivers dependable holding power and long-term reliability where standard fasteners may fail.
Cup Point Design for Strong, Centered Grip
The cup point tip is designed to bite into the mating surface, creating a strong, centered hold that resists both rotational and axial movement. This makes these set screws ideal for securing gears, pulleys, collars, bushings, and rotating shafts. The concentrated point contact ensures consistent alignment and holding force, even under torque, shock, or continuous motion.
Baked Black Oxide Finish Benefits
The baked black oxide finish enhances corrosion resistance while maintaining precise thread dimensions. Unlike thicker coatings, black oxide does not interfere with fit or torque values. It also improves surface lubricity, allowing smoother installation and reducing the risk of galling during tightening. The matte-black appearance provides a clean, professional look, making these fasteners suitable for exposed or visible assemblies.
Nylon Pellet for Vibration-Proof Locking
The defining feature of this set screw is the nylon locking pellet, which is permanently embedded into the threads. When installed, the nylon pellet expands against the mating threads, creating consistent friction that resists loosening caused by vibration, shock, or thermal cycling. Unlike liquid thread-locking compounds, the nylon pellet is reusable, clean, and does not contaminate threads or components—making it ideal for maintenance-friendly applications.
Precision Socket Drive and Standards Compliance
An internal hex (socket) drive allows for accurate torque application using a hex key, even in tight or recessed spaces. These set screws are manufactured from heat-treated alloy steel and conform to ASME B18.3 standards, ensuring dimensional accuracy and reliable performance.
