Solid rivets are measured by their diameter and length.
Below is the range of sizes that they are available in.
Solid rivets come in metric series and inch series.
The diameter is not the actual rivet diameter, it relates to the diameter of the drill bit required to produce a hole to accept the rivet. The real diameter of the rivet is slightly smaller.
The diameter sizes available in the metric series include 1.5, 2, 2.5, 3, 4, 5, 5.5, 6, 7, 8, 9, 10, 11, 12 and 14mm.
Inch series rivet sizes include 1/32, 3/64, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16 and 1/2″.
The inch series lengths include 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/32, 19/32, 5/8, 3/4, 13/16, 7/8, 1, 1 1/16, 1 1/8, 1 1/4, 1 3/8, 1 5/8, 1 3/4, 2 and 2 3/8″.
Grip range
Grip range is the range of thickness that a rivet can hold together. This is always shorter than the length of the rivet’s body as it has to take into account the loss of length caused by the deformation of one end of the rivet.
Measuring the thickness of the materials you want to join together will give you the overall correct grip range so you can determine the length of the rivet you need.
For example, if the material you need to join is 10mm thick, then you will require a rivet length of 14mm which provides a grip range of around 9-11mm.
The diameter of solid rivets is the measurement needed to get the correct rivet for the size of hole you have drilled.
For example if the hole you have drilled is 5mm then the diameter of the rivet needs to be 4.8mm.
