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.

What Does M8 Mean?

M8 is a term that you may have come across when searching for fasteners or bolts online. The M8 designation refers to the size of the bolt or screw, specifically its diameter. An M8 bolt or screw has a diameter of 8 millimeters, making it a medium-sized fastener that is commonly used in various applications.

The “M” in M8 stands for “metric,” which means that the measurement system used is the metric system. This is in contrast to the imperial system, which is commonly used in the United States and other countries. In the metric system, the diameter of a bolt or screw is measured in millimeters, whereas in the imperial system, it is measured in fractions of an inch.

M8 bolts and screws come in different lengths, materials, and designs, depending on their intended application. They can be made of steel, stainless steel, or other metals, and may feature coatings or platings to improve their durability and resistance to corrosion. M8 bolts and screws can be used to fasten objects together or to secure an object to a surface.

It’s worth noting that M8 bolts and screws are not interchangeable, as bolts have a threaded shank that allows them to be screwed into a tapped hole, while screws have a smooth shank that requires a nut to secure them in place.

In summary, M8 is a term that refers to the size of a bolt or screw, specifically its diameter in millimeters.

What Are The Types Of M8 Bolts?

M8 bolts are widely used in various industries, including construction, automotive, and manufacturing. These bolts are known for their durability, strength, and versatility, and are available in different types to suit specific applications. In this article, we’ll explore the various types of M8 bolts and their uses.

  1. Hex Head: Bolts Hex head bolts are the most common type of M8 bolts. They have a six-sided head and are typically used in construction and machinery assembly. These bolts are available in various lengths and materials to suit specific needs.
  2. Socket Head: Bolts Socket head bolts, also known as Allen bolts, have a cylindrical head with a hexagonal socket. They are commonly used in tight spaces where a regular wrench cannot fit. Socket head bolts are ideal for machinery assembly and automotive applications.
  3. Flange Bolts: Flange bolts have a wide, circular flange under the head that distributes the load and provides a larger bearing surface. These bolts are used in applications where a larger surface area is required to prevent the bolt from loosening over time.
  4. Carriage Bolts: Carriage bolts have a round, smooth head and a square shank below it. The square shank prevents the bolt from turning when tightening the nut, making them ideal for applications where the bolt must remain stationary.
  5. Shoulder Bolts: Shoulder bolts, also known as shoulder screws, have a cylindrical shoulder between the head and the threaded section. The shoulder provides a precise and stable location for the attached component, making them ideal for use in machinery and equipment.

In summary, M8 bolts come in various types, each with its unique features and applications. Choosing the right type of bolt for your project is crucial to ensure optimal performance and longevity. Whether you need hex head bolts for construction, socket head bolts for tight spaces, or flange bolts for a larger bearing surface, there is an M8 bolt type to suit your needs.
