Rivet Post Length AdvisorTanner Guild
Calculate the correct rivet post length based on your total leather material stack thickness and hardware style.
The total thickness of all layers of leather to be fastened together.
For proper seating and setting, the rivet shaft must stand proud of the material stack. Double caps require a smaller click clearance, while copper rivets need a longer stem to cut down and hammer mushroom.
