## Overview

The initeq M3-0.5 Threaded Heat Set Inserts are precision-engineered brass inserts designed to permanently add durable metal threads to plastic 3D printed parts. Featuring a polished gold finish and a compact short size, these inserts ensure professional-grade strength and aesthetic appeal for your custom projects.

## Description

Tapered threaded brass inserts for 3D Printing Easy to set in an appropriately-sized hole in the part using a soldering iron. Numerous vanes and ridges around the insert allow plastic to flow between them, creating a tough bond with the printed part. This is a much more versatile, durable, professional, and attractive solution than "captive nuts" and other solutions commonly employed when the need for metal threads in printed parts arises. One primary advantage these provide is the ability to design and print assemblies in multiple component pieces that attach with metal fasteners. This means that you can create products larger than the print volume your printer supports, and that failed prints often result in less waste due to only one part of a larger assembly failing. This also typically results in more "polished", professional-looking designs. Specifications: Thread Pitch: M3-0.5

## Questions & Answers

**Q: What size hole do these need for best strength (width in mm?)**
A: This will depend somewhat on your printer settings and material properties, but a hole tapering from 5.23mm to 5.05mm diameter, depth 3.89mm should be a very good starting point.

**Q: What is the best hole size to get good retention?**
A: On my prints, I have been using 5.60 mm (0.220 inches).  with 1.50 inch depth for the short inserts and 0.250 inches for the longer inserts. It has worked quite well- easy to place the insert on top and sinks down in 1-2 seconds with a soldering iron.

Depending on your screw/bolt length, you might consider add a deeper, smaller hole below the insert so the screw doesn't bottom out.

**Q: What is the length of this product? i am looking for m3 x 0.50 mm thread size, 3.800 mm installed length**
A: Please see the dimensions on the drawing (one of the product images). OAL is 3.81mm

**Q: How long is this produsct from top to bottom? i'm hoping for m3 x 0.50 mm thread size, 3.800 mm installed length**
A: The pieces that I reveived are 3.85mm, 0.1515" +/- a few thousands.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice, but DO NOT FIT VORON STEALTHBURNER  (wrong size)
*by W***E on October 13, 2022*

I got the short ones.Voron general sourcing guide (2022/Oct/13) specifies to use M3xL4xD5, and links to aliexpressVoron stealthburner sourcing guide (2022/Oct/13) links to this product, They measure M3xL3.8xD5.5These are slightly TOO BIG. And folks have complained they bulge the stealthburner parts when inserted.Check the general Voron Sourcing Guide (not the stealthburner one), for links to ones that fit properly.

### ⭐⭐⭐⭐⭐ Work great, and very easy to use
*by E***Y on February 1, 2019*

I picked the the M3 size, and did 5mm wide by 8mm deep holes in PLA. I did end up ordering some of the Virtjoule soldering iron tips to insert these, but no required for these. I run the soldering iron around 700F, and they slowly go in very smoothly without any excess melting. They take a few minutes to cool off, and so far they have all been very snug without feeling like they will be loose. Really the only tips I can give are don't force them in, when warm enough they will insert with a little pressure. Also try to do your best to keep them level when inserting, our you'll find your screws need a slight angle to go in. I was very impressed how they just worked out of the bag.

### ⭐⭐⭐⭐⭐ Works great
*by D***N on June 21, 2022*

These seem to work nicely with M3 screws. I heat-set them using a Hakko FX888D iron and using Virtjoule's heat set installation tips. Very easy to install.
