Suited for Polar 155
Steel Shear Pins for Polar 155. The main shank on this alloy steel shear bolt or safety bolt is 77mm (3-1/32″) long below the head and has an M20 (.79″) thread. The head is 37mm (1-15/32″) in diameter and 12mm (15/32″) thick. The head is cross drilled for a roll pin which is supplied already installed in the head.
Included with each of these shear bolts is a mating M20 washer faced hex nut.
For shear bolts for the earlier Polar 155 paper cutter that do not have the cross pin through the head and that use two shear bolts per pull arm assembly, see our part number S93.
