Projects in the industrial and construction field have access to numerous fasteners, but deciding which is best for a specific job requires knowing how to distinguish between the available fasteners.

Two fasteners commonly brought into this decision are fine thread and coarse thread screws. The main difference is that coarse thread screws or bolts have a larger pitch than fine thread screws. Generally, coarse thread screws are used in many applications and projects, as fine thread screws can be harder to find.

Do you want to learn more about fine thread versus coarse thread screws? In this article, we will discuss what coarse and fine threads mean, the characteristics of each, which is stronger, and the best use cases for each fastener.

Is Fine Thread Stronger Than Coarse?

A significant characteristic to consider when comparing fine thread and coarse is strength. Fine thread bolts are stronger than coarse thread bolts. While coarse thread bolts have a greater pitch, meaning they have fewer threads per axial distance, fine thread bolts have a higher tensile strength.

When To Use Fine Thread Bolts

Fine thread bolts with greater tensile strength make the perfect fastener to use in projects or applications when strength is essential. Their high pitch also makes them greater for withstanding vibrations over time, making them ideal for environments that experience high vibrations. Additionally, with fine threads, shallow peaks and valleys, tapping a hole can be much easier than a coarse thread.

What Are Fine Thread Screws Used For?

When choosing a fastener for a project, consider the installation material being used. It is typically better to use fine thread bolts when working with thicker, more robust gauge metal applications.

When To Use Coarse Thread Bolts

In comparison, it is generally a good idea to use coarse thread fasteners in softer material applications such aluminum and brass.

What Are Coarse Thread Screws Used For?

Coarse thread screws are used more often in construction projects for many reasons, including that even when slightly damaged; they can still be used and function properly. Also, more material can fit between the threads during installation, making it harder for them to strip or cross-thread.
