Typical industries, sizing and material selection." url: https://engineeringhardware.com/applications/specialty-nails/ source: Engineering Hardware & Fasteners --- # What Are Specialty Nails Used For? Nails · Industry standard · Application guide Typical applications, the industries that specify specialty nails, and how to choose the right size, material and finish for the joint. Specialty Nails are used for fast fixing in timber and packaging. They are manufactured to Industry standard, and selection is driven by the size designation, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Fast fixing in timber and packaging - **Governing standard:** Industry standard - **Category:** Nails Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Specialty Nails Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/06/Specialty-Nails-—-Industry-standard.webp) The primary duty of Specialty Nails is fast fixing in timber and packaging. 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 Specialty Nails 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. - **Construction & framing:** fixing timber framing, sheathing and battens. - **Packaging & crating:** closing cases and pallets at speed. ## How to Specify Specialty Nails 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 is a trade-series article rather than one covered by a published dimensional standard, so dimensions can differ between manufacturers. Quote the dimensions you need — or the part you are replacing — rather than a standard number. ## Where Specialty Nails Are Not the Right Choice Not for joints needing later removal or high withdrawal resistance — a screw holds far better in tension. Custom manufacturing · Made to drawing ## Need a specialty nails outside the standard range? A non-standard nail is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling. 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 ### How do I choose the right size of Specialty Nails? Match the size to the mating part using the dimension table on this page. ### Do Specialty Nails hold as well as screws? Nails resist shear well and drive fast, but screws hold far better in withdrawal (tension). Use screws where the joint is loaded in pull-out or may need removal. ### Are Specialty Nails made to a recognized standard? Yes — they are manufactured to Industry standard, so dimensions are interchangeable between suppliers when you quote the standard on your order. ### What are Specialty Nails used for? Fast fixing in timber and packaging. They are supplied to Industry standard. ### Can I get a quote for Specialty Nails in the size and material I need? Yes.
