A cap nut — sometimes called an acorn nut — is a closed-end fastener that threads onto a stud or bolt to secure components while covering and protecting the exposed thread end. By enclosing the thread, it prevents contamination from dust, moisture, and mechanical contact that can cause corrosion or thread damage over time. When a cap nut becomes stripped, cracked, or corroded, it can compromise the clamping force of the joint it secures and leave the underlying threads vulnerable to further damage, making timely replacement important for maintaining the integrity of the assembly.
