Pop Rivets Sizes Chart

Pop rivets can also be called blind rivets and are an ingenious yet simple design for fastening sheet metals without screws. A mandrel, a cylindrical body, and a head make up blind rivets. Blind rivets are made with a riveter and acquire their name because they can be installed without seeing the other side of the materials, hence the name.

The diameter and length of pop rivets/ blind rivets are used to measure them. The diameter in pop rivet sizing does not refer to the diameter of the rivet; instead, it refers to the diameter of the drill bit necessary to create a hole large enough to take the rivet.

The rivet’s actual diameter is slightly smaller. When you install pop rivets, you use a rivet gun that pulls the mandrel through the head, so it swells and then pops. In our guide, you can learn more about attaching a blind rivet, the head styles you can find, and how to determine the correct size drill bit you need.

How Do I Choose The Right Size Pop Rivet?

Before any pop rivet installation, you need to know a few things before commencing. Here are things that lead to choosing the right pop rivet sizes.

Hole Size

During the installation of a pop rivet, the size of the hole is crucial. Of course, a too-small hole will make rivet insertion problematic. On the other hand, the shear and tensile strengths will be reduced if the hole is too large.

Allowing the rivet body to extend between the members rather than just on the blind side may create bulging or separation of the members.

Grip Range

The total thickness range for a hole of the specified diameter in which the body length will consistently provide a suitable.

Shear

The force is exerted on a fastener when it passes through the joint contact.

Tensile Strength

The force exerted on a fastener along its entire length.

Joint Strength

Determine the single-joint tensile and shear values needed for the installation first. Total joint strength, fastener spacing, rivet body material, and rivet diameter are all factors.

Then, for the rivets you’re using, look up the shear and tensile strengths for the length.

The thickness of the Joints

The overall thickness of the materials to be connected should be measured. This determines the required “grip” of the rivet you choose.

It would help if you chose a rivet with a grip range that encompasses the required work thickness. Remember that if the rivet length is insufficient, the secondary head at the back of the work will not form properly.

Also note that the setting mandrel does nothing for the grip, or the hole size of the rivet, you simply insert the rivet and the mandrel forms the bulge on the pop rivet as you use the rivet gun.

Materials

The ultimate joint strength is affected by both the rivet and the materials to be secured.

Because a significant difference in physical and mechanical properties between the rivet materials and the materials to be fastened can cause joint failure because of material fatigue or galvanic corrosion.

A best practice is to try and match the rivet materials’ physical and mechanical properties of the materials to be fastened. (Learn How To Unscrew A Rusted Screw)

Rivet Head Design

Most applications are suitable for the low-profile domed head.

The big flange head should be considered when soft or fragile materials are secured to a stiff backing as they provide double the bearing surface.

Determining the exact size of pop rivets for the job is critical, but choosing the right rivet style for your application is equally crucial.

  • Closed-End Rivets: These two-piece pop rivets offer a lot of versatility, a lot of vibration resistance, and a lot of tidy installations.
  • Open-End Rivets: Also known as nail rivets vary from closed-end rivets in that they do not provide a preventative seal against liquid or vapor escape.
  • Micro Rivets: Micro rivets have a diameter of 2 millimeters or less, making them ideal for small applications like printed circuit boards and other electronic devices.
  • Multi-Grip Rivets: These provide a more extensive grip range than regular pop rivets and accommodate big and irregularly sized holes.

Assessing the size and kind of pop rivet, as well as the substance the rivet is constructed of, assures that your application will be successful and that the rivet will withstand the rigors of long-term use.

Pop Rivet Points

Pop rivets were invented in 1934 and allow users to place a rivet from one side of the material.

To establish the right size for pop rivets, measure the hole size, body length, grip range, and head size.

Closed-end, open-end, micro, and multi-grip pop rivets are among the various varieties available.

How do you calculate the length of pop rivets?

The grip range of a rivet is the range of thicknesses it can hold two pieces of material together. This is always less than the rivet’s body length because it must account for the length loss produced by the distortion of one end of the rivet when it is ‘popped.’

Measuring the thickness of the components you wish to link will give you the overall correct grip range, allowing you to figure out how long the rivet should be.

For example, if the material you’re joining is 10mm thick, you’ll need a 14mm rivet with a 9-11mm grip range.

The diameter of solid or blind rivets is the measurement required to select the rivet for the size of the hole drilled. (Read Torx Screw Size Chart)

For example, if the hole you drilled is 5mm in diameter, the rivet should be 4.8mm in diameter.

What Size Is A #10 Rivet?

Here you can find a quick overview of available blind rivet sizes. For more detail, check the rivet size chart above.

The diameter size for blind rivets are:

  • Metric series – 2.4, 3, 3.2, 4, 4.8, 5, 6.4 and 7.4mm.
  • Inch series – 3/32, 1/8, 5/32, 3/16, 1/4, and 19/64″.

The metric lengths for blind rivets:

4, 4.5, 5, 6, 7, 8, 10, 12, 14, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 175, 180 and 190mm.

Inch series lengths include:

5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 3/4, 13/16, 7/8, 15/16, 1, 1 1/32, 1 1/16, 1 1/8, 1 1/4, 1 9/32, 1 3/8, 1 5/8, 1 3/4, 2, 2 3/16, 2 3/8, 2 5/8, 2 3/4, 3, 3 1/8, 3 1/2, 4, 4 1/2, 4 3/4, 5 1/4, 5 1/2, 6, 6 11/32, 6 3/4, 7, 7 1/4 and 7 1/2″.

The higher the size of blind rivets, the stronger the secured connection in both shear and tension.

Aluminum rivets with aluminum mandrels are the weakest; aluminum rivets with steel mandrels are stronger; steel rivets with steel mandrels are even more substantial, and stainless steel rivets with either steel or stainless steel mandrels are the most powerful.

Closed-end rivets have more shear and tensile strength than open-end rivets of the same size and material when fastened to your materials.
