Properties of M12 Bolts

M12 bolts have a number of properties that make them suitable for use in high-strength applications. They have a diameter of 12mm and are available in a range of lengths and thread pitches. The most common thread pitch for M12 bolts is 1.75mm, although other thread pitches are also available. M12 bolts are made from a variety of materials, including steel, stainless steel, and titanium. Steel M12 bolts are the most common and are often used in applications where high strength is required. Stainless steel M12 bolts are resistant to corrosion and are often used in applications where exposure to moisture or chemicals is a concern. Titanium M12 bolts are strong, lightweight, and resistant to corrosion, making them suitable for use in high-performance applications.
Advantages of M12 Bolts
M12 bolts have a number of advantages that make them a popular choice for use in a wide range of applications. They have high strength and are resistant to deformation, making them suitable for use in situations where heavy loads are applied. M12 bolts are also resistant to corrosion, particularly when made from stainless steel or titanium. They are easy to use and can be installed using a variety of tools, including wrenches and sockets. M12 bolts are also relatively inexpensive compared to other types of bolts, making them a cost-effective option for many applications.
Material | Yield Strength | Ultimate Strength |
---|---|---|
Steel | 600 MPa | 800 MPa |
Stainless Steel | 500 MPa | 700 MPa |
Titanium | 900 MPa | 1000 MPa |

Uses of M12 Bolts

M12 bolts are used in a wide range of applications, including construction, automotive, and industrial manufacturing. They are commonly used to join two or more parts together, particularly in situations where high strength is required. M12 bolts are often used in conjunction with nuts and washers to provide a secure and reliable fastening system. They are also used in a variety of other applications, including engine mounts, suspension systems, and steering components.
Disadvantages of M12 Bolts
While M12 bolts have a number of advantages, they also have some disadvantages. They can be heavy, particularly when made from steel, which can make them difficult to handle and install. M12 bolts can also be prone to rust and corrosion, particularly when exposed to moisture or chemicals. In addition, they can be expensive, particularly when made from high-strength materials such as titanium.
