Rivets · Trade series (turn-button fastener eyelets) · Application guide Typical applications, the industries that specify turn-button fastener eyelets, and how to choose the right size, material and finish for the joint. Turn-Button Fastener Eyelets are used for setting the fabric-side eyelet that engages a matching turn-button base. They are manufactured to Trade series (turn-button fastener eyelets), and selection is driven by the screw size, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Setting the fabric-side eyelet that engages a matching turn-button base - **Governing standard:** Trade series (turn-button fastener eyelets) - **Screw size range:** 1-1/16 to 1-1/16 - **Category:** Rivets Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Turn-Button Fastener Eyelets Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Turn-Button-Fastener-Eyelets.webp) Turn-Button Fastener Eyelets are used primarily for setting the fabric-side eyelet that engages a matching turn-button base. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to Trade series (turn-button fastener eyelets). Stocked across roughly 1 to 1, they cover light-duty and instrument-scale work. ## Typical Applications for Turn-Button Fastener Eyelets The most common settings where these are specified: - **Canvas fabrication:** Eyelets provide the fabric-side half of a turn-button connection. - **Boat covers:** Nickel-plated brass supports removable fabric-to-solid-surface attachment. - **Vehicle trim:** Two height options accommodate the mating base and material stack. - **Upholstery:** The eyelet engages a base without adding a threaded nut to the fabric.

This product spans 1–1; 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 (turn-button fastener eyelets). 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 Turn-Button Fastener Eyelets - 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 Turn-Button Fastener Eyelets 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 turn-button fastener eyelets 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.

Side view and top view, drawn to the dimensions in the table below and redrawn for any size selected. - **Height options (in):** 13/16 - **Material:** nickel-plated brass - **Mating part:** turn-button base - **Use:** fabric-to-solid-surface attachment ## Dimensions & Specifications (Trade series (turn-button fastener eyelets)) | Eyelet diameter (in) | Height options (in) | Material | Mating part | Use | | --- | --- | --- | --- | --- | | 1-1/16 | 13/16 | nickel-plated brass | turn-button base | fabric-to-solid-surface attachment | | 1-1/16 | 27/32 | nickel-plated brass | turn-button base | fabric-to-solid-surface attachment | 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. ## Frequently Asked Questions ### Which industries use Turn-Button Fastener Eyelets? They are commonly specified in boat covers, vehicle trim and upholstery, among other sectors. ### How do I choose the right size of Turn-Button Fastener Eyelets? Select on screw size and on the fit the assembly requires. This product is available from 1 to 1; the full dimension table on this page lists each size. ### Can Turn-Button Fastener Eyelets 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 Turn-Button Fastener Eyelets 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. ### Can I get a quote for Turn-Button Fastener Eyelets in the size and material I need? Yes.
