Rivets · Trade series (mechanically locked breakstem) · Application guide Typical applications, the industries that specify structural breakstem blind rivets, and how to choose the right size, material and finish for the joint. Structural Breakstem Blind Rivets are used for structural blind riveting with a mechanically retained breakstem. They are manufactured to Trade series (mechanically locked breakstem), and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Structural blind riveting with a mechanically retained breakstem - **Governing standard:** Trade series (mechanically locked breakstem) - **Nominal diameter range:** 4.8 mm to 10 mm - **Category:** Rivets Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Structural Breakstem Blind Rivets Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Structural-Breakstem-Blind-Rivets.webp) Structural Breakstem Blind Rivets (Trade series (mechanically locked breakstem)) are specified where the joint requires structural blind riveting with a mechanically retained breakstem. 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 4.8 mm to 10 mm, they cover general to heavy-duty work. ## Typical Applications for Structural Breakstem Blind Rivets The most common settings where these are specified: - **Commercial vehicles:** structural blind joints in frames and box sections. - **Cladding systems:** one-side sheet fastening with a mechanically retained stem. - **HVAC enclosures:** high-volume structural riveting without rear access. - **Rail equipment:** vibration-exposed joints using a filled structural rivet body.

This product spans 4.8 mm–10 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 Trade series (mechanically locked breakstem). 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 Structural Breakstem Blind 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 Structural Breakstem Blind Rivets Are Not the Right Choice Not where the joint must later be disassembled, and not for high-tension structural connections. Custom manufacturing · Made to drawing ## Need a structural breakstem blind rivets outside the standard range? Grip range is what a special usually changes — a joint thickness that falls between two standard rivets. Made by cold heading or drawing. Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

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. ## Frequently Asked Questions ### Are Structural Breakstem Blind Rivets made to a recognized standard?
