## Applications & Industries

What Closed-End Round-Body Blind Rivet Nuts are specified for, industry by industry. Stocked from M4 to M10.

### Industries that specify Closed-End Round-Body Blind Rivet Nuts

- **Outdoor enclosures:** Cover and bracket attachment points exposed to water and dirt.
- **HVAC fabrication:** Panel hardware installed after the duct or enclosure has been formed.
- **Refrigeration equipment:** Sealed threaded mounting points in formed panels and closed housings.
- **Vehicle bodywork:** Blind threads in rails and box sections where the cavity must stay closed.
- **Automotive & transport:** Vibration-prone joints where the locking type is specified on the drawing.
- **Maintenance & MRO:** Replacements matched to the existing bolt class, thread and finish.

### Typical applications

- forming the blind bulb within the specified grip range
- choosing steel, stainless steel or aluminum for the service environment
- adding a sealed internal thread from the front face of a panel
- keeping water and debris out of a closed section behind the insert
- joints re-torqued at a service interval
- completing a bolted joint on a stud, rod or bolt

### Service conditions to specify against

- **Marine and coastal:** Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- **High load:** Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
- **Match the class:** A nut below the bolt property class strips before the bolt reaches its own limit — pair class 8 nuts with 8.8 bolts, class 10 with 10.9.

### Where to use something else

- Do not drill to the thread minor diameter; the installation hole is set by the body and forming requirements.

Manufactured to Trade series (closed-end blind rivet nuts), Closed-End Round-Body Blind Rivet Nuts are nuts supplied by Engineering Hardware. The dimensional data, materials and selection notes are summarized here.

## What Are Closed-End Round-Body Blind Rivet Nuts?

Closed-End Round-Body Blind Rivet Nuts are nuts defined by Trade series (closed-end blind rivet nuts). They are selected by thread size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

## Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), alloy steel in property classes 8.8, 10.9 and 12.9, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, property class and surface finish appropriate to your load and environment.

## Specification Guides

Each size, material and standard of Closed-End Round-Body Blind Rivet Nuts has its own reference page with the figures for that one configuration.

## Goes With

Hardware commonly specified alongside Closed-End Round-Body Blind Rivet Nuts.

## Pricing

Closed-End Round-Body Blind Rivet Nuts are supplied to order. Pricing starts from approximately US$0.12 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

Custom manufacturing · Made to drawing

## Need a closed-end round-body blind rivet nuts outside the standard range?

Thread size is the obvious variable and rarely the interesting one — height for clearance, across-flats for the tool already in the cell, and the locking feature for the vibration actually present. Made by cold heading or tapping.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

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](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 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.
