Description
The M20 Thin Flat Washer is a standard metric flat washer used throughout Virtus Equipment and ZERMA America granulators and shredders wherever M20 fasteners are installed. Washers serve a critical function in machine assemblies — they distribute the clamping load of the bolt head or nut across a wider surface area, prevent bolt heads from pulling through or damaging softer mating surfaces, and provide a consistent bearing surface for accurate torque application. Using the correct washer specification ensures joint integrity and prevents premature fastener loosening under the vibration loads typical of granulator and shredder operation.

Key Features:
Load Distribution: Spreads M20 bolt clamping force across a wider bearing area, protecting mating surfaces and preventing fastener pull-through in high-vibration machine environments.
OEM-Specification Profile: Thin washer geometry matches the original Virtus Equipment and ZERMA America assembly specifications for M20 fastener positions.
Consistent Torque Surface: Smooth, flat bearing surface ensures accurate torque application and repeatable clamping force during assembly and maintenance.
Vibration Resistance: Proper washer use in conjunction with correct bolt torque reduces fastener loosening under the continuous vibration loads of granulator and shredder operation.
Bulk Availability: Available individually or in bulk quantities — washers are a high-consumption consumable and recommended for maintenance department stocking programs.
This thin washer profile is the standard specification for M20 positions across the Virtus Equipment and ZERMA America product line. The M20 size is the most commonly used large-diameter fastener across these machines, making this washer one of the highest-priority hardware items to keep in maintenance stock. Always pair with the appropriate M20 bolt (hex or cap head) and replace washers any time fasteners are removed and reinstalled during routine maintenance or component replacement.
Compatibility: Virtus Equipment and ZERMA America granulators and shredders (multiple models — see machine parts documentation)
