Blades are only as secure as the hardware holding them. This pre-owned 10-32 × 1/2" button head screw fastens blades to the blade core of the Industrial Cannabis Grinder, keeping the two- or four-blade configuration locked in through every run. A full blade core uses 18 screws, so keeping extras on hand are an inexpensive insurance against a stripped head on cleaning day, allowing you to keep your pre-roll production running at speed.
