About Blind Rivets

Blind rivets are named so because they can be installed without access to the back side of the item being riveted. They are composed of the rivet (green) and an integrated mandrel (orange). They can often be referred to a POP Rivets.

How blind rivets work

Blind rivets are installed in a tight hole that passes through the materials being riveted. A riveter is used to pull the mandrel back while holding the rivet in place. As the mandrel is pulled back it deforms the rivet pushing the sides outward until the mandrel snaps. This expanded size forms the back side of the rivet holding the materials together.

Types

There are several common types of blind rivets each with its own advantages. The most common are:

Standard
These rivets are the most common blind rivets and the least expensive. However, they are not water tight and are not as strong as some other rivet types.

Sealed
These rivets are similar to standard rivets except that the mandrel is completely enclosed. The result is that when installed sealed rivets are water tight.

Multi-grip
These rivets are specifically designed for situations where you don't know how long a rivet you might need (the grip). They are more expensive than standard rivets, but when a long length is used on thin material they compact, leaving less material hanging off the back as shown below.

Head Styles

Dome
Considered standard, dome is the most common head style.

Flat
Countersunk for a Flush Fit

Oversize
A larger head typically used in softer materials to increase the load bearing area.
