Stainless Steel Cup-Tip Set Screws

These corrosion-resistant cup-tip screws grip parts tightly. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

Military Specification—These screws are manufactured and tested to strict U.S. military standards for material and construction.
