Round Head Rivit

A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the tail. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset, or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place .  Round head rivets from Pankaj International are permanent mechanical fasteners designed for robust and secure connections. Featuring a smooth cylindrical shaft with a head on one end and a tail on the other, these rivets are installed by placing them into a punched or drilled hole and then deforming the tail to expand approximately 1.5 times its original diameter, ensuring a strong hold.
