Metric Bolt offers both metric and standard sized fasteners, bolts, screws, and more.

Metric fasteners and standard fasteners are two types of fasteners that are commonly used in construction, manufacturing, military supply chain, and other industries. The main difference between them is the units of measurement used to describe their sizes.

While both types of fasteners serve the same purpose, they are not interchangeable. Using the wrong type of fastener can result in a weakened or damaged structure, and can also cause safety hazards. It is important to use the appropriate type of fastener for a given application and to adhere to the appropriate specifications and standards.

Metric Bolt distributes imperial and metric fasteners throughout the United States of America.

With that being said, continue reading to discover more about metric vs standard fasteners in more detail.

What is a metric fastener?

Metric fasteners are measured using the metric system of measurement, which is based on units of millimeters (mm), centimeters (cm), and meters (m).

Metric fasteners are typically used in countries that have adopted the metric system, such as most of Europe, Asia, and Australia.

What is a standard fastener?

Standard fasteners, on the other hand, are measured using the imperial measurement system, which is based on units of inches (in) and fractions of an inch.

Standard fasteners are commonly used in countries that have not fully adopted the metric system, such as the United States.

Which measurement system is best?

There is no clear-cut answer to whether fasteners using the metric system or fasteners using the imperial system are better. The choice between the two types of fasteners largely depends on several factors, including the following:

  • The type of application
  • The specifications of the materials being used
  • The availability of the fasteners in a particular region

Are metric measurements better for you?

In general, metric fasteners tend to be more precise and offer a wider range of sizes than standard fasteners, since they are based on the metric system which has more precise increments. This can be an advantage in applications where precision is critical, such as in aerospace or medical equipment.

Situations whereby the standard system is better

On the other hand, standard fasteners, i.e. those using the imperial measurement system, are still widely used and readily available in many parts of the world, especially in the United States. They may also be more cost-effective in certain applications, especially for smaller sized fasteners, since they are often produced in higher volumes.

Metric Bolt offers a wide array of standard fasteners and metric fasteners for the military supply chain.

Should you buy a metric bolt or a standard fastener?

To determine which type of fastener to use for a given application, there are several factors that should be considered:

  1. Application requirements – Consider the specific needs of the application, including load-bearing requirements, environmental conditions, and other factors that may impact the performance of the fastener.
  2. Material specifications – Ensure that the fastener material is compatible with the materials being joined. Different materials may require different types of fasteners.
  3. Availability – Consider the availability of the fasteners in the desired size and quantity. Some sizes and types may be more readily available in metric or standard versions depending on the location.
  4. Standards and specifications – Consider any industry or DFARs material standards that may apply to the application. Some industries may require the use of specific types of fasteners.
  5. Expert advice – Consult with a knowledgeable supplier or engineer who can provide guidance on the appropriate type of fastener for the application.

By considering these factors and seeking expert advice, you can determine which of the measurement systems is right for you. This will help ensure that the fasteners provide reliable and long-lasting performance.

Metric Bolt is a leading supplier to the US Military offering a wide range of metric fasteners and standard fasteners.

Choosing the best expert who can help you with the imperial or metric measurement system

When choosing an bolt supplier for metric and standard fasteners, there are several factors that you may want to consider:

  1. Experience – Look for an expert with significant experience in the fastener industry. This can include experience in engineering, manufacturing, and/or sales of fasteners.
  2. Knowledge – The expert should have a deep understanding of the properties and performance of various types of fasteners, such as metric bolts and standard and metric wrenches, as well as the ability to recommend the most appropriate fasteners for a given application.
  3. Reputation – Look for an expert who is well-regarded in the industry and has a track record of providing high-quality fastener products and services.
  4. Customer service – The expert should be responsive and attentive to your needs, and able to provide clear and accurate information about their products and services.
  5. Certifications – Look for an expert who holds relevant certifications, such as ISO 9001, which indicates that they meet international quality management standards.
  6. Price and value – Consider the expert’s pricing and the overall value they offer. While cost is important, it should not be the sole factor in your decision-making.

The choice between metric and standard systems

Ultimately, the choice between metric and standard fasteners will depend on the specific needs of the project or application. It is important to consult with a knowledgeable supplier like Metric Bolt or engineer to ensure that the appropriate type of fastener is selected for a given application.
