When considering Friction and Bearing on Bolts, what are ' ...

Solution

Where bolts are solidly cast into concrete - i.e. are set to Non-Adjustable - the bolts can be relied upon to resist shear.

In this case, the design may be based on effective bearing length in concrete of 3d and an average bearing stress of 2 fcu.  For more about this see the related article linked at the bottom of this article.

Where bolts are not solidly cast into concrete i.e. set to are Adjustable, some allowance can be made for a reduction of the bearing on the bolts capacity via the factors "Factor * d" , which adjusts the bolt bearing length, and "Factor * fcu" which adjusts the concrete bearing stress.  The default value of both factors is 1.0.

• Factors of 3 and 2 respectively provide the same resistance as if the bolts were solidly cast (Non-Adjustable) - this would be un-conservative.
• Factors of 0 and 0 assume the bolts provide no shear resistance  - this would be conservative.

The values to use for your connection is a matter for your engineering judgement - we cannot provide specific advice on the values to be used.

Bearing Bolt vs. Friction Bolt: Decoding the Key Differences.

So, you're in the market for bolts, but you're unsure about the differences between bearing bolts and friction bolts. Don't worry - we've got you covered. Let's dive into the key distinctions between these two types of bolts to help you make an informed decision for your next project.

1. What are Bearing Bolts?

Bearing bolts, also known as structural or heavy hex bolts, are designed to provide a strong, secure connection between two structural elements. These bolts are commonly used in construction projects, such as building bridges and high-rise buildings. Bearing bolts have a larger head size compared to standard bolts, providing increased bearing surface area for enhanced grip and stability.

2. What are Friction Bolts?

Friction bolts, on the other hand, are designed to provide a secure connection by creating friction between two surfaces. These bolts are ideal for applications where movement or vibration may occur, as the friction created helps to prevent loosening over time. Friction bolts are commonly used in machinery and automotive industries.

3. Key Differences Between Bearing Bolts and Friction Bolts.

One of the main differences between bearing bolts and friction bolts is their design and intended use. Bearing bolts are designed to withstand heavy loads and provide a secure connection, while friction bolts are better suited for applications where movement or vibration may occur.

Another key difference is the head size of the bolts. Bearing bolts have a larger head size to provide increased bearing surface area, while friction bolts have a standard head size. This difference in head size affects the grip and stability of the bolts in various applications.

4. Which Bolt is Right for You?

The choice between bearing bolts and friction bolts ultimately depends on the specific requirements of your project. If you need a strong, secure connection for heavy loads, bearing bolts may be the best option. On the other hand, if you anticipate movement or vibration in your application, friction bolts may be more suitable.

5. Conclusion.

In conclusion, bearing bolts and friction bolts have key differences in their design and intended use. Understanding these differences can help you choose the right bolt for your project.
