Have you ever bent your case pusher bolt during a critical loading session? It happens and it isn't a part you normally have lying around the shop. We went looking for a better part and found it.
This is an upgraded alloy shoulder screw comparable to Grade 8 steel and a 12,000 psi nylon roller.
It does require that your cash pusher be countersunk (meaning the shoulder fits into the pusher body). Some older pushers are not. Please check before ordering.
