Semi Tubular Rivets

Semitubular Rivet Dimension "L" Determined By Application

What length to use?

1. View the chart below.

2. Find the body diameter you are using. (the D dimension)

3. All the way to the right of the graph you will find a "suggested clinch allowance. Add that number to the total thickness you are looking for. That is the "approximate length you will need.

example: If you are using a 1/4 body diameter, than add .157 to your total thickness. This will be the approximate length you need.

Semi-tubular rivets (also known as 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 semitubular rivet is about 1/4 of the amount needed to apply a solid rivet. Tubular rivets can also be used as pivot points (a joint where movement is preferred) since the swelling of the rivet is only at the tail.
