Keps Nuts 18/8 Stainless 4-40 are compact, corrosion-resistant fasteners engineered for reliable, vibration-resistant assemblies. The Keps nut design features a built-in washer integrated into the nut body, providing a larger bearing surface and a fast, drop-in installation without needing a separate washer.
Made from 18/8 stainless steel (commonly referred to as type 304), these nuts offer superior rust and corrosion resistance, making them well-suited for both indoor and outdoor use, including light outdoor and marine-adjacent environments. The 4-40 thread size makes them ideal for small-scale hardware projects, electronics, and precision assemblies.
For best results, pair these nuts with compatible 4-40 screws and tighten with the appropriate tool to achieve the desired preload and holding power.
