Stainless Steel Cup-Tip Set Screws
Thread-Locking Steel Cup-Tip Set Screws
 |
These screws grip parts tightly and give you extra protection against mild vibration. They have a nylon-patch threadlocker bonded to the threads, saving you the time and mess of adding it yourself. Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.
Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.
