What Are Quick-Release Pins, Push-Button Used For?

Typical applications, the industries that specify quick-release pins, push-button, and how to choose the right size, material and finish for the joint.

Quick-Release Pins, Push-Button are used for connections made and broken by hand many times, where a threaded fastener would be far too slow. They are manufactured to Trade series (push-button quick-release pin), and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

What Are Quick-Release Pins, Push-Button Used For? application image

Quick-Release Pins, Push-Button (Trade series (push-button quick-release pin)) are specified where the joint requires connections made and broken by hand many times, where a threaded fastener would be far too slow. 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 mm to 10 mm, they cover general to heavy-duty work.

Typical Applications for Quick-Release Pins, Push-Button

The most common settings where these are specified:

  • General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
  • Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
  • Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
  • Jigs & fixtures: precise location of tooling plates and locating features.
  • Linkages & hinges: pivot points carrying light shear.

How to Specify Quick-Release Pins, Push-Button for Your Application

  • Size: Select on nominal diameter, then on the hole tolerance and fit class — the fit, not the diameter alone, determines whether the part locates or slips. This product spans 4 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 (push-button quick-release pin). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Installation & Assembly Practice

  • Ream the hole to the specified fit class; a dowel pressed into a drilled-only hole will not locate accurately.
  • Press pins in with steady force rather than hammer blows where possible, and chamfer the hole entry.

Common Selection Mistakes with Quick-Release Pins, Push-Button

  • Using a dowel pin as a load-carrying shear bolt — dowels locate, they are not sized for sustained shear.
  • Ignoring the fit class: a locational fit and an interference fit need different hole tolerances.

Where Quick-Release Pins, Push-Button Are Not the Right Choice

Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that.

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
    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
    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
    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
    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 Quick-Release Pins, Push-Button?

They are commonly specified in fabrication & metalwork, jigs & fixtures and linkages & hinges, among other sectors.

How do I choose the right size of Quick-Release Pins, Push-Button?

Select on nominal diameter and on the fit the assembly requires. This product is available from 4 mm to 10 mm; the full dimension table on this page lists each size.

What material should Quick-Release Pins, Push-Button 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.

Are Quick-Release Pins, Push-Button made to a recognized standard?

Yes — they are manufactured to Trade series (push-button quick-release pin), so dimensions are interchangeable between suppliers when you quote the standard on your order.

Can I get a quote for Quick-Release Pins, Push-Button in the size and material I need?

Yes. Use the technical drawing and quote form on this page to set the size and options, then send the exact configuration to our team for pricing and lead time.
