Description
The M20 × 70 Hex Head Bolt is a high-strength metric hex head fastener used throughout Virtus Equipment and ZERMA America granulators and shredders. The 70 mm length provides extended thread engagement for applications requiring greater fastening depth than the standard M20 × 60 configuration — particularly in rotor assembly and cutting chamber installations where component stack-up or mounting plate thickness demands additional bolt length. The full hex head design allows for high-torque installation with standard metric wrenches and sockets.

Key Features:
M20 × 70 mm Dimensions: Extended 70 mm length provides greater thread engagement depth than M20 × 60 for applications with thicker mounting surfaces or component stack-up requirements.
DIN 933 / ISO 4017 Standard: Fully threaded hex head bolt manufactured to internationally recognized dimensional standards for reliable fitment and interchangeability.
Class 10.9 High-Strength Steel: Delivers the clamping force required for heavy-duty granulator and shredder fastening applications subject to vibration and high-load cycling.
Hex Head Drive: Standard hexagonal head allows installation and removal with common metric wrenches and sockets — no special tooling required.
Direct OEM Replacement: Specified for use in Virtus Equipment and ZERMA America machines — consult your machine’s parts documentation for exact installation locations and torque specifications.
Applications:
As with all fasteners used in granulator and shredder assemblies, proper installation torque is critical — always torque to the manufacturer’s specified value for M20 Class 10.9 fasteners and inspect at regular service intervals. Replace any fasteners showing signs of thread damage, corrosion, or deformation immediately.
