If you’re in the manufacturing or construction industry, you may have come across the term “M8 bolt” or “M8 screw.” But for those who are not familiar with this hardware, it can be confusing to understand what exactly it refers to.
In this article, we will explore the basics of M8 bolts and screws, including their size, usage, and common variations. Whether you’re a professional or a DIY enthusiast, this guide will provide you with a comprehensive understanding of M8 bolts and screws.
What Is An M8 Bolt Or M8 Screw?
An M8 bolt or M8 screw is a type of fastener that is commonly used in various applications, including manufacturing, construction, and DIY projects. The “M8” in its name refers to its size, which is determined by its diameter in millimeters. Specifically, an M8 bolt or screw has a diameter of 8 millimeters.
M8 bolts and screws come in various lengths, materials, and designs, depending on their intended application. They are typically made of steel, stainless steel, or other metals, and some may feature coatings or platings to improve their corrosion resistance or aesthetic appearance. M8 bolts and screws can be used to join two or more objects together or to fasten an object to a surface.
It’s worth noting that M8 bolts and screws are not interchangeable, as the former has a threaded shank that allows it to be screwed into a tapped hole, while the latter has a smooth shank that requires a nut to secure it in place. M8 bolts and screws are commonly used in automotive, aerospace, and industrial applications, as well as in furniture assembly and other DIY projects.
