Blind Rivet Series

How to measure a blind rivet

📏 Key Dimensions of a Blind Rivet:

  1. Rivet Diameter (Body Diameter)

    • This is the outer diameter of the rivet body (the shell).

    • It must match the hole diameter in the materials you're fastening.

    • Common sizes: 3.2mm (1/8”), 4.0mm (5/32”), 4.8mm (3/16”), etc.

  2. Grip Range (Material Thickness Range)

    • The grip range refers to the total thickness of the materials the rivet is designed to fasten.

    • You’ll find this range on datasheets (e.g., 1.5–3.5 mm).

    • Always choose a rivet with a grip range that covers your material thickness.

  3. Rivet Length (Body Length)

    • This is the length of the rivet body, not including the mandrel.

    • The length must be long enough to allow for proper expansion and secure fastening.

    • Too short = insufficient clamp. Too long = risk of weak joint.

📌 Example:

Let’s say you’re working with two metal sheets that total 3.0 mm in thickness.
You’ll need:

  • A rivet with a grip range that includes 3.0 mm (e.g., 2.5–4.0 mm)

  • A diameter matching your drilled hole (e.g., 4.8 mm)

  • A length long enough to form a proper backside head

🛠 Pro Tip from KSEET:

When in doubt, choose a rivet with a slightly longer grip range and test for pull strength. KSEET offers customized blind rivet solutions and technical support — just reach out and we’ll help you find the perfect match for your application.
