Types of Metric Bolts

When it comes to metric bolts, there are several different types to choose from. In this section, we’ll cover three main types of metric bolts: machine screws, ISO standard bolts, and IFI standard bolts.

Machine Screws

Machine screws are a type of metric bolt that are typically used in machinery and other industrial applications. They are characterized by their small size and fine threads, which are designed to fit into pre-tapped holes. Machine screws come in a variety of sizes and materials, and can be used for a wide range of applications.

ISO Standard Bolts

ISO standard bolts are another common type of metric bolt. These bolts are designed to meet specific standards set by the International Organization for Standardization (ISO). ISO standard bolts are available in a wide range of sizes and materials, and are used in a variety of applications, including construction, automotive, and industrial.

IFI Standard Bolts

IFI standard bolts are a type of metric bolt that are designed to meet specific standards set by the Industrial Fasteners Institute (IFI). These bolts are available in a variety of sizes and materials, and are used in a wide range of applications, including construction, automotive, and industrial.

Understanding Metric Bolt Sizes

If you’re working with metric bolts, it’s important to understand the sizing system used for these fasteners. In this section, we’ll cover the basics of metric bolt sizes, including diameter and pitch, as well as the differences between UNC and UNF threads.

Diameter and Pitch

Metric bolt sizes are typically expressed in millimeters, with the diameter of the bolt being the first number in the measurement. For example, an M8 bolt has a diameter of 8 millimeters. The pitch of the bolt refers to the distance between the threads, and is also expressed in millimeters. So an M8 x 1.25 bolt has a diameter of 8 millimeters and a thread pitch of 1.25 millimeters.

It’s important to note that the diameter of a bolt is not the same as the size of the wrench you’ll need to use to tighten it. Instead, the wrench size is determined by the bolt’s hex head, which is typically one size larger than the bolt diameter.

UNC vs UNF Threads

In addition to diameter and pitch, it’s important to understand the differences between UNC and UNF threads when working with metric bolts. UNC stands for “Unified National Coarse,” while UNF stands for “Unified National Fine.” The difference between the two is the number of threads per inch.

UNC threads have fewer threads per inch than UNF threads, making them better suited for applications where strength is more important than precision. UNF threads, on the other hand, have more threads per inch, making them better suited for applications where precision is more important than strength.

As a trusted wholesale distributor for over 65 years, Fastening Specialists is your go-to source for all your fastening needs. With our expertise, we can help you find the right metric bolts for your application, whether you need UNC or UNF threads, or a specific diameter and pitch. Trust the specialists for the best in product value, insight, code expertise, and order fulfillment.

Installation and Usage

Proper Drilling Techniques

When it comes to installing metric bolts, proper drilling techniques are essential. The size of the hole should match the diameter of the bolt, and the hole should be drilled perpendicular to the surface. Using a drill press or a guide can help ensure accuracy. It is also important to use the correct drill bit material and speed for the material being drilled.

Fastening Specialists can provide you with the right tools and expertise to ensure that your drilling is done properly. As a trusted wholesale distributor for over 65 years, we are specialists in this field. With our vast knowledge and experience, you can trust us to provide you with the best products and advice for your specific needs.

Engaging Female Threads

Engaging female threads is another important aspect of proper installation and usage of metric bolts. It is important to ensure that the threads are clean and free of debris before engaging the bolt. The bolt should be turned by hand until it is snug, and then tightened with a wrench to the appropriate torque.

At Fastening Specialists, we understand the importance of properly engaging female threads. Our team of experts can provide you with the right tools and guidance to ensure that your bolts are installed correctly. With our extensive product knowledge and code expertise, you can trust us to provide you with the best solutions for your fastening needs.

Maintenance and Care

Proper maintenance and care are essential for ensuring the longevity and strength of metric bolts. With the right care, you can prevent rust, corrosion, and wear, which can significantly reduce the lifespan and strength of your bolts.

To maintain your metric bolts, it is essential to store them in a dry and cool place. Avoid exposing them to moisture, which can cause rust and corrosion. You can also use protective coatings, such as zinc or phosphate, to prevent rust and corrosion.

Regular inspection is also crucial for maintaining the strength and integrity of your metric bolts. Inspect them for signs of wear, corrosion, or damage, and replace them if necessary. Make sure to use the right tools and equipment when installing or removing bolts to avoid damaging them.
