## Description

Specifications: M3 Wire Thread Inserts Material: Stainless Steel Fit Drilling Diameter: 3mm pitch: 0.5mm Overall Length: 1D Outter Diameter: 3mm Feature: Stainless steel threaded inserts can effectively improve threaded connections and greatly improve reliability. Threaded inserts are used in a variety of low strength materials to greatly improve the wear resistance of threaded connections and avoid thread damage. Package Included: 80Pcs M3 x 0.5mm x 1D Wire Thread Inserts

Review: Sold as 1.5D, but only has 7 full threads. With a 1.5mm pitch that puts it at 10.5mm in length, which is just barely over the 10mm expected of a 1D thread insert. They work otherwise, but I didn't specifically pick a 1.5D thread insert just for giggles, I needed those extra 3 threads. The product specs and images are a lie, so whether or not it's intentional that earns it an instant 1 star. (In the image it shows even smaller than 10.5mm in length, but the threads are stretched a bit during installation)
Review: We use these for our laser cut acrylic projects for when we need screws in to the plastic. These always work

## Features

- Fit Drilling Diameter: 3mm; pitch: 0.5mm; Overall Length: 1D.
