A Cap Nut — sometimes called an acorn nut — is a closed-end fastener that threads onto a bolt or stud to secure an assembly while covering and protecting the exposed thread end. On a tandem roller like the RD18-100 series, fastener integrity is critical because the machine operates under continuous vibration; a loose or damaged nut can allow components to shift, accelerating wear on surrounding parts. Replacing a worn or stripped Cap Nut promptly with the correct OEM part maintains the clamping security the assembly was designed to deliver.
