Rivets · Trade series (spring button clips) · Application guide Typical applications, the industries that specify spring button clips, and how to choose the right size, material and finish for the joint. Spring Button Clips are used for retaining telescoping round or square tubing with a spring button that engages a matching hole. They are manufactured to Trade series (spring button clips), and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Retaining telescoping round or square tubing with a spring button that engages a matching hole - **Governing standard:** Trade series (spring button clips) - **Nominal diameter range:** 14~18 mm tubing to 14~18 mm tubing - **Category:** Rivets Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Spring Button Clips Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Spring-Button-Clips.webp) The primary duty of Spring Button Clips is retaining telescoping round or square tubing with a spring button that engages a matching hole. Below: the sectors that specify them in volume, the checklist used to select the right size and material for the application, installation notes, and the known limits of the type. Stocked across roughly 14 mm to 14 mm, they cover heavy and structural work. ## Typical Applications for Spring Button Clips The most common settings where these are specified: - **Telescoping tubes:** Spring button clips let round or square sections lock at repeated positions. - **Adjustable frames:** A projecting button gives a positive manual detent. - **Furniture and displays:** Small tube assemblies change height without loose hardware. - **Field equipment:** Spring steel or stainless options follow the environment.

This product spans 14 mm–14 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 (spring button clips). 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 Spring Button Clips - 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 Spring Button Clips 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 spring button clips 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 ### What material should Spring Button Clips be for outdoor use?
