Choosing the right Rivet size

Follow this quick and simple guide to measuring and selecting the right rivet for your job.

Rivet sizes

measure grip range

1. Measure the grip range.

This will be the total thickness of the materials being joined together.

2. Choose the diameter of rivet required

The bigger the diameter of rivet body (d) = the stronger the join.


3. Check the data sheet for the chosen rivet type.

This will contain a table to locate the diameter and grip range (G) that will indicate length required.

A ‘3.2 Diameter’ rivet is required to join two metal plates with a grip (G) of 8.0mm.
The data sheet table shows a 12mm body length is required.

Check the Nosepiece size

Rivet tool nosepiece

The correct nosepiece on your setting tool must be correct. Even if the rivet will fit in the end of the nose piece, it may be incorrect – which could lead to the mandrel sticking or the tool jamming. Measure the rivet body diameter and ensure it it within range of the nose piece capacity. This is usually stamped on the end of the nosepiece. Check before setting.
