18-8 Stainless Steel Vibration-Resistant Cap Locknuts
A nylon patch bonded to the threads of these reusable nuts adds friction to prevent loosening under vibration. However, the patch's strength lessens with each use. These nuts have good chemical resistance and may be mildly magnetic because they’re made of 18-8 stainless steel. Also known as acorn nuts, they have a smooth rounded head that covers and protects threads while providing a finished appearance.
