Tips for Choosing the Right Blind Rivet Size


Blind rivets are high-performance fasteners that have the potential to last for a long period compared to other rivets. In addition, rivet bolts are easy to install and forms a permanent bond that resists corrosion and vibration. This is one of the significant reasons why blind rivets are used in a wide range of industrial applications, from automotive and agriculture to consumer electronics. However, as with any type of rivet nuts, it’s essential to choose the right materials and size to get the long-lasting performance.

What Is A Blind Rivet?

Blind rivets are also called POP rivets. POP rivets are used in applications where there’s no access to another side of the equipment. Rivets is a two-piece construction, rivet body, shell, or hat and stem or mandrel. Both the parts are pre-assembled and ready to use. They can be installed using a riveting tool to draw the mandrel, causing the body to deform and clamp down on the joints. On reaching the clamping force, the mandrel is discarded after snapping. Blind rivets can be used for many applications, including RVs, aircraft, machinery, jeans, trailers, small electronics, battleships, structural beams, submersibles, and machinery.

Generally, blind rivnut is made of steel, aluminium, stainless steel, copper, zinc, nickel-copper, and other materials. It’s of utmost importance to choose a rivet material that matches both sides of the equipment, and the size is also right for the hole and thickness of the equipment.

Key Factors to Consider When Choosing Blind Rivet Size

Hole size

Since blind rivets are installed in pre-drilled holes, and you have to ensure that the rivet matches the hole for a perfect fit. If the diameter of the rivet nut is too small or big, either the joint may loosen, or it won’t fit inside the hole. On the other hand, if it’s too tight, it’s hard to fit inside the hole. Before purchasing, measure the size of the hole to buy the right sized rivets.

Joint Strength

The strength of the joint is determined by the shear and tensile strength of the rivet bolt. You will have to ensure that the material and diameter of the rivet nut is sufficient to withstand the load and length of the joint.


It’s essential to ensure the material of the rivet nut matches with the material used in the equipment that is being fastened together.

Size of the Head and Mandrel

The rivet head size visibility depends on the application. The head size should be big enough so that it doesn’t pull out. On the other hand, the size of the mandrel is equally important so that it fits perfectly.

These are the key considerations that you need to factor in when buying rivet nuts from rivet suppliers.
