# What Are Thread Insert Installation Tools Used For?

Tools · DIN 8140 (wire thread inserts) — installation tooling · Application guide

Typical applications, the industries that specify thread insert installation tools, and how to choose the right size, material and finish for the joint.

Thread Insert Installation Tools are used for installing, adjusting or servicing the assembly rather than forming part of it. They are manufactured to DIN 8140 (wire thread inserts) — installation tooling, and selection is driven by the size designation, the fit and tolerance the assembly requires, and the service environment.

- **Primary duty:** Installing, adjusting or servicing the assembly rather than forming part of it
- **Governing standard:** DIN 8140 (wire thread inserts) — installation tooling
- **Category:** Tools

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

Thread Insert Installation Tools are used primarily for installing, adjusting or servicing the assembly rather than forming part of it. 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 DIN 8140 (wire thread inserts) — installation tooling.

## Typical Applications for Thread Insert Installation Tools

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.

## How to Specify Thread Insert Installation Tools 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 product is supplied to DIN 8140 (wire thread inserts) — installation tooling. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Where Thread Insert Installation Tools Are Not the Right Choice

Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.

Custom manufacturing · Made to drawing

## Need a thread insert installation tools 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.

## Technical Drawing

Dimensioned line drawing of STI tap Thread Insert Installation Tools to DIN 8140 (wire thread inserts) — installation tooling. Side view and top view, drawn to the dimensions in the table below and redrawn for any size selected.

- **Step in the sequence:** cuts the oversize thread for the insert
- **Sized by:** insert thread size
- **Notes:** not the same as an ordinary tap of that size

## Dimensions & Specifications (DIN 8140 (wire thread inserts) — installation tooling)

| Tool | Step in the sequence | Sized by | Notes |
| --- | --- | --- | --- |
| STI tap | cuts the oversize thread for the insert | insert thread size | not the same as an ordinary tap of that size |
| insertion mandrel / tool | winds the insert to depth | insert thread size | sets the insert one half-pitch below the face |
| tang break-off punch | removes the driving tang | insert thread size | the tang must be removed and retrieved |
| extraction tool | removes a failed insert | insert thread size | for rework |
| key-locking insert tool | drives the keys into the parent metal | insert thread size | for key-locking inserts, not wire inserts |

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.
