Welcome to Virtus Equipment Direct
M16 x 50 mm DIN 912 / ISO 4762 socket head cap screw used as the pulling adjusting bolt for the stator knife adjustment system of Virtus Equipment and ZERMA America ZRS 800 and ZCS 1400 machines. Grade 12.9. Also sold under SKU 80040228 — these are the same part. Works as a matched pair with pushing bolt (80011290) to set and hold the stator knife cutting gap. Consult your machine’s parts documentation to confirm the correct quantity. Sold individually.
The Adjusting Bolt for Pulling DIN 912 M16 x 50 12.9 is a socket head cap screw used in the stator knife adjustment system of Virtus Equipment and ZERMA America ZRS 800 and ZCS 1400 machines. This part is also sold under SKU 80040228 — both SKUs refer to the same identical part. In the stator knife adjustment system, the pulling bolt draws the stator knife toward the rotor to reduce the cutting gap, while the paired pushing bolt (80011290) moves it away to increase the gap. The 50 mm length is specific to the thread engagement depth on the pulling side of the stator knife bracket. Both bolts are required to properly set and lock the stator knife position. Correct gap maintenance directly affects cut quality, fines generation, and knife service life. Grade 12.9 construction provides 1,220 N/mm² minimum tensile strength. Consult your machine’s parts documentation to confirm the correct quantity before ordering. Sold individually.
