Note 1: Special contacts refer to the contact rivets which have chamfer or pit or hollow on the shank.
     Note 2: For the contact rivets with head thickness no more than 0.5mm, the rivet mould is made according to drawing demould angle requirement, while the contact rivet demould angle is not assessed.
