Description
The M16 Cover Disc is a protective cover used on Virtus Equipment and ZERMA America granulators and shredders to cap M16 bolt head recesses, mounting holes, and fastener positions on machine guards, panels, hoppers, and structural components. In granulator and shredder environments, open fastener recesses and bolt holes quickly accumulate regrind dust, plastic fines, and debris — material that packs tightly into counterbores and can make routine bolt removal extremely difficult during maintenance. Cover discs prevent this contamination, keeping fastener positions clean and accessible and maintaining the machine’s professional appearance over its service life.
