Nickel Cup-Tip Set Screws

The most corrosion-resistant set screws we offer. Made of nickel, these screws match 316 stainless steel's strength but outperform it in salt water and harsh acid environments. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts. 400 Nickel is also known as Monel.
