Blind Rivets … (most commonly called pop rivets) are measured by their diameter and then by the specific “grip range”.

The diameter is based on the diameter of the rivet body.

The “grip” is based on the thickness of the material being riveted. The “Grip Range” is the minimum and the maximum grip that the rivet is intended to be used with.

NOTE ……..It is very important to understand that the maximum grip range is NOT the overall length of the rivet body.

We carry the following sizes in our store.

1/8 rivets …. Which are identified with a starting number 4

3/16 rivets … Which are identified with a starting number 6

1/4 rivets …. Which are identified with a starting number 8

The second number is the key to the grip range.
Here is the grip range that corresponds to the second number:

2      grips from 1/32 to 1/8

4      grips from 1/8 to ¼

6      grips from ¼ to 3/8

8      grips from   3/8 to ½

10    grips from ½ to 5/8

12    grips from 5/8 to ¾

16    grips from ¾ to 1”

So….. a rivet that is labeled 6-10 would be a 3/16” rivet that would grip material ranging from a minimum of ½ thick, up to a maximum thickness of 5/8

A 44 rivet would be 1/8 diameter and can grip from 1/8 to 1/4.

So there it is!….. Now you can choose the right rivet for the job!
