Grading System for Bolts: What You Need to Know

Bolts play a crucial role in various industries, and understanding their grading system is vital to selecting the right bolt for the job. The grading system classifies bolts based on their material and mechanical properties, which are essential for ensuring safety and reliability.

Understanding Bolt Grades

Bolt grades reflect the composition and strength of a bolt. Different materials, such as stainless or carbon steel, influence the bolt's durability and load-bearing capacity. The higher the grade number, the stronger the bolt.

Common Bolt Grade Systems

Two primary systems are used for grading bolts:

  1. Metric (ISO): Metric bolts have grades like 4.6, 4.8 (mild steel), 5.6, 6.6 (mild steel/high tensile), 8.8 (high tensile), 10.9, 12.9 (automotive industry), and 14.9 (high-grade steel).
  2. Imperial (SAE): Grades include Imperial Grade B (mild steel), P, T, V, and X, as well as British Standard Fine (BSF), British Standard Whitworth (BSW), and British Association Grade (BA), all marked on the bolt head.

Identifying Bolt Grades

Bolt grades are typically etched on the bolt head, with different markings for metric and imperial systems. For example, metric bolts might be marked with the grade number, while imperial bolts might have letters like 'B', 'P', 'T', 'V', or 'X'.

Significance of Bolt Grades in Application

Selecting the correct bolt grade is crucial for the bolt's suitability in various applications. Higher-grade bolts are necessary for heavy machinery due to their enhanced strength, ensuring safety and durability.

Choosing the Right Bolt Grade

When selecting a bolt grade, consider environmental exposure, load requirements, and specific project needs. For a comprehensive range of bolt options, visit Fabory's bolt section.

Maintenance and Inspection of Bolts

Regular maintenance and inspection, including checking for wear and corrosion, ensure the bolts remain fit for purpose and extend their lifespan.

Innovations and Future Trends in Bolt Grading

The field of bolt manufacturing is evolving, with advancements in materials and grading techniques promising more precise grading systems.

Conclusion

Understanding bolt grades is essential for selecting the right bolt for specific applications, ensuring safety and efficiency.

What Is Bolting Cloth Mesh? (Definition, Applications, and ...

We have seen countless screen media get used for hundreds of applications across dozens of industries throughout the years. Whether it be perforated plate or woven wire mesh, identifying a screen media suitable for your needs is a critical step when achieving desirable results.

But as with any tool, the more specialized it is to a specific task, the better it will perform for you. This is why many people implement materials such as bolting mesh into their process.

Having landed on this page, odds are you are curious as to what bolting cloth is and if it can be applied to your process.

Here at W.S. Tyler, we feel it's our responsibility to be as transparent as possible even if it is discovered that woven wire mesh is not right for you. This is why our team of experts works to leverage the 140 years of experience within our four walls to educate you on if and how wire mesh can benefit your operation.

To ensure we stick to our word, the following article was put together to share what we know about bolting cloth and will cover:

 

  • What bolting cloth is

  • The applications bolting cloth specializes in

  • Why you should use wire mesh to construct your bolting cloth

  • How much bolting cloth costs

 

What Is Bolting Cloth Mesh?

In the world of woven wire mesh, bolting refers to a mechanism that executes several rapid movements to deliver the desired results. Bolting cloth mesh, also referred to as tensile bolting cloth, is a woven mesh variation that features a plain, square mesh profile and is designed to make the bolting elements of your operation more efficient.

In the past, materials such as nylon and silk were synonymous with bolting cloth mesh. This is because it was a cheap way to achieve the fine pore opening bolting cloth is known for.

However, in more recent years, woven wire mesh, specifically stainless steel wire mesh, has become the predominant material used.

How Is Bolting Cloth Mesh Used?

As bolting cloth generally falls under the fine mesh classification, it is widely used for screen printing and the sifting of fine particles.

The increased amount of pore openings in the mesh allows manufacturers to depict a substantial amount of detail when screen printing. This means bolting mesh excels when screen printing various high-detailed products, such as printed circuit boards.

The higher, precise mesh count of bolting cloth can also be applied to the aggregate and mining industries. The fine mesh profile of bolting cloth is often used to sift fine particles such as various sand particles.

With that said, the characteristics of bolting cloth have also been applied to several filtration applications that call for accurate filtration without sacrificing throughput.

 

Why Use Wire Mesh Bolting Cloth?

As stated above, nylon, silk, and metallic wires can all be used to weave bolting cloth. However, stainless steel wire mesh bolting cloth is possible the most widely used.

This is because the metallic properties of wire mesh help deliver several beneficial qualities that make it stand out. These qualities are tension capabilities, durability, and precision.

 

Tension Capabilities

In order to deliver optimal accuracy, bolting cloth is often brought into tension. That said, wire mesh bolting cloth has less than 1% elongation when tensioned, whereas materials like nylon can exceed 5% elongation.

In other words, stainless steel can withstand higher tension loads without compromising the integrity of the mesh openings.

 

Durability

Even when thinner wires are used to achieve the fine pore openings of bolted cloth, woven wire mesh is far more durable than silk and nylon. In fact, once the diameter of nylon or silk goes beneath a certain threshold, they cannot be tensioned without damage.

This threshold is much lower when working with wire mesh, making it ideal when extremely fine mesh specifications are needed.

 

Precision

During the bolting process, bolting cloth made from nylon or silk tends to flex. This creates the potential for the pore openings to become skewed, altering the accuracy of the cloth.

Wire mesh is a much more rigid material that minimizes flexing. As a result, the accuracy of the mesh opens is preserved, which is reflected through the end product.

Additionally, wire mesh can be calendered, which involves running the mesh through two rollers to reduce the thickness of the mesh. This crushes the knuckles at each wire intersection, stabilizing the pore openings of the mesh while also creating a smoother surface that better facilitates bolting.

How Much Does Wire Mesh Bolting Cloth Cost?

Much like other wire mesh solutions, there is no set price for wire mesh bolting cloth. This is because several factors control the price of your bolting cloth.

These factors include:

 

  • Wire diameter

  • Mesh count

  • The dimension of the mesh (i.e., mesh rolls or cut-to-size pieces)

  • Any value-added services needed (i.e., calendering)

Get To Know How Bolting Cloth Differs From Filter Cloth

Bolting cloth is woven wire square mesh specifically designed to facilitate the bolting actions associated with screen printing and various sifting applications. Compared to other materials used to weave bolting cloth, woven wire square mesh delivers enhanced precision, durability, and tensioning capabilities.

Now, we mentioned that bolting cloth could sometimes be used for filtration applications. As it is specifically designed for screen printing and sifting, you must get to how bolting cloth compares with wire mesh specifically designed for filtration before implementing either.
