Semi-tubular rivets

Semi-tubular rivets are used instead of rivets for fixing of compounds, and often they are used where necessary to create not rigid connection, but, for example, swivel.

Semi-tubular rivets are similar to solid rivets, except they have a partial hole (opposite the head) at the tip. The purpose of this hole is to reduce the amount of force needed for application by rolling the tubular portion outward. The force needed to apply a semi-tubular rivet is about 1/4 of the amount needed to apply a solid rivet.

Semi-tubular rivet has several advantages :

attractive view;

much lower laboriousness when unriveting;

does not corrode when coating with zinc.

Also semi-tubular rivets are used for compound of leather details.
