Looking for a screw

[u/GreenCactus223]

Hello Team,

I have a remington 870 tactical express, I juat noticed one of the screws on the picatinny rail is missing. Can anyone tell me where I can buy a replacment? I saw it on amazon but it also saod frequently returned. I would appreciate any insight, as for size I dont know if its No.6 or No.8 but ill mic it at the shop tomorrow.

it's a standard short rail that came with the rifle.

also wanted, to ask if i Can change it from a slot screw to a torque screw, I saw an option for torque screws online but not sure if anyone has done it.
