What Are Metric and Imperial Fasteners?

Metric Fasteners Overview

Metric fasteners are used in many places. They use the metric system for measuring. This means they measure length in millimeters and meters. You see labels like M6 or M8 on them. The “M” means metric. The number tells the diameter in millimeters. Metric fasteners use thread pitch. Thread pitch shows the space between threads in millimeters. This helps you measure very exactly. Most places outside the U.S. use metric fasteners. You find them in cars, electronics, and machines from Europe or Asia. Metric fasteners help you match parts and tools easily. This is helpful when working with suppliers from other countries.

Imperial Fasteners Overview

Imperial fasteners follow old British rules from 1824. You measure these in inches and feet. Here are some important facts about imperial fasteners:

• Sizes are shown in inches, feet, or thou.
• Thread pitch is measured by threads per inch.
• Common thread types are UNC and UNF. Both have a 60° thread angle.
• Stress and pressure use pound force per square inch.
• Standards come from groups like AISI, ANSI, ASME, ASTM, and SAE.

Imperial fasteners are found in many things made in the U.S. They are also used in older machines and some industries that use U.S. rules.

Global and Regional Usage

It is important to know where each type is used. The table below shows the main places for each fastener:

Think about where your project will be used before you pick fasteners. Prince Fastener can help you choose the right type for your area and job.

Key Differences in Fasteners

Measurement Systems and Units

Fasteners use different ways to measure size. The metric system uses millimeters and meters. The imperial system uses inches, feet, and pounds. This changes how you read sizes and pick tools. Look at the table below for a quick comparison:

Always check which system your project needs before buying fasteners.

Thread Pitch vs. Thread Count

Thread pitch and thread count help match bolts and nuts. The metric system uses pitch. Pitch means the space between threads in millimeters. The imperial system uses threads per inch (TPI). Mixing these means parts will not fit. See the table below for the main differences:

You can ask Prince Fastener for help if you are not sure which thread type you need.

Strength Grades and Markings

You need to know the strength of your fasteners for safety. Metric and imperial fasteners use different markings. Metric fasteners use numbers like 8.8 or 10.9. Imperial fasteners use grades like 2, 5, or 8. The table below shows how these compare:

Use these markings to pick the right fasteners for your project.

Compatibility Issues

Mixing metric and imperial fasteners can cause problems. You might see stripped threads, loose joints, or even broken parts. The table below lists problemas comuns:

Tip: Always use the same system for all fasteners in your project. This helps you avoid mistakes and keeps your work safe.
