• Knurled Cup Set Screws

Knurled Cup Set Screws

South Coast Fasteners, Inc. supplies knurled cup set screws built for extra grip in demanding applications. These screws combine a standard cup point with a knurled edge inside the cup, giving them added bite against the mating surface. That added friction makes a difference, especially in assemblies that deal with constant motion, heavy torque, or continuous vibration.

Knurled cup set screws are ideal for locking parts in place where standard set screws might work loose over time. They are commonly used in motors, pulleys, collars, and mechanical assemblies where staying tight matters. If your build needs lasting hold under pressure, these are the screws built to handle it.
