# What Are Turn-Button Fastener Bases Used For?

Rivets · Trade series (turn-button fastener bases) · Application guide

Typical applications, the industries that specify turn-button fastener bases, and how to choose the right size, material and finish for the joint.

Turn-Button Fastener Bases are used for mounting the solid-surface half of a removable fabric connection with matched screw spacing. They are manufactured to Trade series (turn-button fastener bases), and selection is driven by the size designation, the fit and tolerance the assembly requires, and the service environment.

- **Primary duty:** Mounting the solid-surface half of a removable fabric connection with matched screw spacing
- **Governing standard:** Trade series (turn-button fastener bases)
- **Category:** Rivets

Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation.

The primary duty of Turn-Button Fastener Bases is mounting the solid-surface half of a removable fabric connection with matched screw spacing. 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.

## Typical Applications for Turn-Button Fastener Bases

The most common settings where these are specified:

- **Marine canvas:** Turn-button bases anchor removable fabric panels to a solid surface.
- **Vehicle covers:** Single- and double-stud bases retain trim and soft covers.
- **Upholstery:** Nickel-plated brass gives a finished visible mounting point.
- **Outdoor equipment:** Base spacing and screw size are matched to the support.

## How to Specify Turn-Button Fastener Bases for Your Application

- **Size:** Match the size to the mating part — see the dimension table below for each option.
- **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 bases). 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 Bases

- 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 Bases 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 bases 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.

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.
