## Applications & Industries

Nut Drivers and Nut Setters are bought for a small number of well-defined jobs. These are the ones we ship them for. Stocked from 5.5 mm to 17 mm (nominal size).

### Industries that specify Nut Drivers and Nut Setters

- **Automotive trim:** Small hex fasteners.
- **Roofing and cladding:** Hex-washer-head screws all day.
- **Control panel build:** Small hex nuts and standoffs.
- **HVAC:** Duct and sheet fixings.
- **Assembly & maintenance:** Installing and servicing the fasteners in this catalog.

### Typical applications

- choosing the depth so the washer seats without over-driving
- sizing by the across-flats, not by the thread
- using a magnetic setter for hex-head roofing screws
- replacing a setter whose socket has belled out
- driving and releasing fasteners on the bench and in the field

### Where to use something else

- Do not keep using a nut setter whose socket has rounded; it starts to spin on the head and that damages the screws, not the tool.

- **Fits:** M3 hex nut
- **Form:** nut driver / nut setter
- **Typical use:** electronics, sheet metal

Every row below is a starting point for the customizer above — pick any size and the drawing will redraw to that row.

| Across flats | Fits | Form | Typical use |
| --- | --- | --- | --- |
| 5.5 mm | M3 hex nut | nut driver / nut setter | electronics, sheet metal |
| 7 mm | M4 hex nut | nut driver / nut setter | sheet metal, control panels |
| 8 mm | M5 hex nut, ST4.2 hex-head screw | magnetic nut setter | self-drilling screws |
| 10 mm | M6 hex nut, ST5.5 hex-head screw | magnetic nut setter | roofing and cladding screws |
| 13 mm | M8 hex nut, ST6.3 hex-head screw | magnetic nut setter | roofing, purlin fixing |
| 17 mm | M10 hex nut | nut driver | general assembly |

Nut Drivers and Nut Setters are tools manufactured to Trade series (hexagon nut drivers, across-flats sized). This page lists the full dimensional range with the key specifications engineers need to select and specify them.

## What Are Nut Drivers and Nut Setters?

Nut Drivers and Nut Setters are tools defined by Trade series (hexagon nut drivers, across-flats sized). They are selected by nominal size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

## Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.

## Goes With

Hardware commonly specified alongside Nut Drivers and Nut Setters.

## Pricing

Nut Drivers and Nut Setters are supplied to order. Pricing starts from approximately US$0.90 per piece for standard sizes in the catalog specification; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

Custom manufacturing · Made to drawing

## Need a nut drivers and nut setters outside the standard range?

A non-standard fastener tool 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.
