Pins · Trade series (quick-release pin receptacles) · Application guide Typical applications, the industries that specify quick-release pin receptacles, and how to choose the right size, material and finish for the joint. Quick-Release Pin Receptacles are used for receiving a quick-release pin in a threaded or surface-mounted receptacle with the correct reduction. They are manufactured to Trade series (quick-release pin receptacles), and selection is driven by the screw size, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Receiving a quick-release pin in a threaded or surface-mounted receptacle with the correct reduction - **Governing standard:** Trade series (quick-release pin receptacles) - **Screw size range:** 1/2 in to 5 / 6 / 8 / 10 / 12 / 16 mm - **Category:** Pins Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Quick-Release Pin Receptacles Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Quick-Release-Pin-Receptacles.webp) Quick-Release Pin Receptacles are used primarily for receiving a quick-release pin in a threaded or surface-mounted receptacle with the correct reduction. 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 (quick-release pin receptacles). Stocked across roughly 1 to 5, they cover light-duty and instrument-scale work. ## Typical Applications for Quick-Release Pin Receptacles The most common settings where these are specified: - **Tooling fixtures:** Thread-in receptacles receive removable pins for rapid changeover. - **Agricultural equipment:** Surface-mount forms support field-adjustable attachments. - **Access panels:** Stainless receptacles provide a repeatable pin seat. - **Material handling:** Usable reduction controls how far the pin enters the barrel.

This product spans 1–5; 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 (quick-release pin receptacles). 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 Pin Receptacles - 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 Pin Receptacles Are Not the Right Choice Not for carrying significant tensile or repeated heavy shear loads — use a bolt or a keyed joint for that. Custom manufacturing · Made to drawing ## Need a quick-release pin receptacles outside the standard range? Tolerance class is what a special pin usually turns on — a locating pin and a retaining pin want very different fits in the same nominal size. Made by cold heading or turning. 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 are Quick-Release Pin Receptacles used for?
