Cup Point Nylon Patch Socket Set Screw with Black Oxide Plating – Reliable Locking Power with a Clean Finish
When you need a fastener that stays locked in place under high-stress conditions, the Cup Point Nylon Patch Socket Set Screw with Black Oxide Plating offers dependable performance and added protection. These precision-engineered set screws are designed to provide lasting holding power without marring or damaging the mating surface, making them a go-to choice for precision applications across a wide range of industries.
The cup point design features a concave tip that concentrates holding pressure at a single point. This allows the screw to grip the mating surface securely without causing unnecessary wear, making it ideal for frequent adjustments or repositioning—especially in shafts, collars, and rotating components.
The nylon patch adds a self-locking element that resists vibration and prevents unintentional loosening. Unlike traditional thread-locking compounds, the pre-applied nylon patch is clean, reusable, and ideal for applications requiring consistent torque and repeated installation.
Finished with a black oxide coating, these screws have a sleek, matte appearance that provides mild corrosion resistance and reduces glare. While black oxide is best suited for indoor, controlled environments, it also improves the screw’s surface hardness and aesthetics.
