For Ø 6 mm rivets
Brass square washers to buck Ø 6 mm rivets
Square washers are very useful to buck the rivets on material such as leather, rawhide, fabric and wood.
You can place a square washer under the head of the rivet and another one on the other side of the assembly on the tail of the rivet which you will buck.
The solidity of the assembly will be then optimised.
