What Are Blind (Pop) Rivets Used For?

Typical applications, the industries that specify blind (pop) rivets, and how to choose the right size, material and finish for the joint.

Blind (Pop) Rivets are used for permanent, vibration-proof joints in sheet and plate. They are manufactured to ISO 15977 / DIN 7337, and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

What Are Blind (Pop) Rivets Used For? application image

Blind (Pop) Rivets (ISO 15977 / DIN 7337) are specified where the joint requires permanent, vibration-proof joints in sheet and plate. The sections below cover the typical end-uses by industry, the size and material decisions for each, assembly practice, and the applications this fastener type is not suited to. Stocked across roughly 2.4 mm to 6 mm, they cover light-duty and instrument-scale work.

Typical Applications for Blind (Pop) Rivets

The most common settings where these are specified:

  • Sheet-metal assembly: permanent joints in ductwork, panels and enclosures.
  • Bodywork & trailers: blind joints where only one side is accessible.
  • Signage & cladding: fast, vibration-resistant fixing of thin panels.
  • General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
  • Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.

How to Specify Blind (Pop) Rivets for Your Application

  • Size: Select on nominal diameter, then on the hole tolerance and fit class — the fit, not the diameter alone, determines whether the part locates or slips. This product spans 2.4 mm–6 mm; check the full table below for the exact dimensions of each size.
  • Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
  • Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
  • Standard: This product is supplied to ISO 15977 / DIN 7337. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Installation & Assembly Practice

  • Drill the hole 0.1 mm over the nominal rivet diameter and deburr both sides before setting.
  • Grip range must match the total joint thickness — a rivet set outside its grip range clamps poorly and works loose.

Common Selection Mistakes with Blind (Pop) Rivets

  • Setting a rivet outside its grip range, which leaves the joint loose from day one.
  • Using aluminum rivets on steel sheet outdoors — galvanic corrosion eats the rivet.

Where Blind (Pop) Rivets Are Not the Right Choice

Not where the joint must later be disassembled, and not for high-tension structural connections.

Inside the plant

Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

  1. Wire rod feeding into a cold heading machine
    01

    Cold heading

    Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.

    Head dimensions and under-head radius checked at set-up and per shift.

  2. Thread rolling machine producing bolt threads
    02

    Thread rolling

    Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.

    Go / no-go ring gauges to ISO 965 tolerance class 6g.

  3. Baskets of bolts staged for heat treatment
    03

    Heat treatment

    Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.

    Core hardness and tensile tested per lot to ISO 898-1.

  4. Zinc plated bolts in a treatment basket
    04

    Surface treatment

    Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.

    Coating thickness and neutral salt spray hours to ISO 9227.

Frequently Asked Questions

Can Blind (Pop) Rivets joints be taken apart?

No — rivets form a permanent joint and must be drilled out to remove. Use a bolt or screw where you need to disassemble the joint later.

What material should Blind (Pop) Rivets be for outdoor use?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

Are Blind (Pop) Rivets made to a recognized standard?

Yes — they are manufactured to ISO 15977 / DIN 7337, so dimensions are interchangeable between suppliers when you quote the standard on your order.

What are Blind (Pop) Rivets used for?

Permanent, vibration-proof joints in sheet and plate. They are supplied to ISO 15977 / DIN 7337.
