We also offer Italian rivets of excellent performance. From our extensive experience in manufacturing the most important thing for rivets is that they mustn’t be too hard, because if the force applied during riveting is too strong it may result in distortion and deformation, and that can later cause clutch disc imbalance.


We offer steel hollow rivets in the following sizes:

4x5 5x6 6x6
4x6 5x7 6x9
4x7 5x9 6x12
4x9 5x11  
4x11 5x14  

Rivets are sold in 1000 pieces packages.


Aluminium full rivets:



Steel and aluminium rivets are sold in 1000 pieces packages and that is the minimum amount to order.
