# What Are Screw-Shank Nails Used For?

Nails · Trade series (screw-shank nails) · Application guide

Typical applications, the industries that specify screw-shank nails, and how to choose the right size, material and finish for the joint.

Screw-Shank Nails are used for fixing timber with a helical shank that increases withdrawal resistance in the specified wood. They are manufactured to Trade series (screw-shank nails), and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

- **Primary duty:** Fixing timber with a helical shank that increases withdrawal resistance in the specified wood
- **Governing standard:** Trade series (screw-shank nails)
- **Nominal diameter range:** 6 mm to 20 mm
- **Category:** Nails

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

Screw-Shank Nails are used primarily for fixing timber with a helical shank that increases withdrawal resistance in the specified wood. 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 (screw-shank nails). Stocked across roughly 6 mm to 20 mm, they cover general to heavy-duty work.

## Typical Applications for Screw-Shank Nails

The most common settings where these are specified:

- **Timber framing:** Spiral and ring shanks increase withdrawal resistance in wood joints.
- **Pallet and crate assembly:** Nails close packaging where a driven screw-like shank is useful.
- **Outdoor construction:** Galvanized and stainless options follow the exposure.
- **Deck and fence repair:** Gauge and length are selected with the board thickness.

## How to Specify Screw-Shank Nails 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 6 mm–20 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 (screw-shank nails). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Where Screw-Shank 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 screw-shank 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.

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

### What are Screw-Shank Nails used for?

Fixing timber with a helical shank that increases withdrawal resistance in the specified wood. They are supplied to Trade series (screw-shank nails).

### Which industries use Screw-Shank Nails?

They are commonly specified in outdoor construction, deck and fence repair and timber framing, among other sectors.

### How do I choose the right size of Screw-Shank Nails?

Select on nominal diameter and on the fit the assembly requires. This product is available from 6 mm to 20 mm; the full dimension table on this page lists each size.

### Do Screw-Shank 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.

### Can I get a quote for Screw-Shank Nails 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.
