Nickel Socket Head Screws

The strongest ultra-corrosion-resistant screws we offer, these withstand some of the harshest acids and salt water. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.

Length is measured from under the head.

Ultra-Corrosion-Resistant 400 Nickel—As strong as 316 stainless steel screws and outperform them in salt water and harsh acids. 400 nickel is also known as Monel.

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.
