Knurl Cup Set Screws
Knurl cup point socket set screws are designed for maximum holding power in high‑vibration and high‑torque applications. Featuring a knurled serrated edge around a deep cup‑shaped point, these screws bite securely into the mating surface to prevent slippage, backing out, or rotation. The combination of the cup point and knurled periphery provides aggressive grip, making them ideal for applications requiring strong axial and radial holding force.
Commonly used in machinery, pulleys, collars, rotating equipment, and mechanical assemblies, knurl cup set screws provide a secure fastening solution where traditional cup or cone points might not offer sufficient resistance. The internal hex drive allows for easy installation and removal while ensuring stable torque transfer in tight or recessed locations.

Knurl cup set screws deliver superior performance in applications subject to continuous movement, vibration, or shock. The knurled outer rim creates additional friction against the shaft or component surface, while the cup point generates a firm, centered seat that prevents misalignment or creep over time.
These screws are valued in industrial manufacturing, machinery repair, automation systems, and drive assemblies where strong holding power is essential. Available in a variety of materials, finishes, and thread sizes, knurl cup set screws provide reliable fastening strength for both light‑duty and heavy‑duty mechanical requirements.
