## Overview

The initeq M3-0.5 Threaded Heat Set Inserts provide a reliable and permanent metal threading solution for 3D printed parts. Designed for easy heat-set installation, this pack of 100 short inserts enhances the durability and functionality of your prints, making them ideal for professional-grade prototyping and production.

## 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.
