Product Details

AS 2451 BSW threaded hexagon head bolts are a specific specification of fasteners. AS 2451 is an Australian standard that specifies the technical requirements and test methods for bolts and other threaded fasteners. BSW (British Standard Whitworth) is an early British standard thread type, also known as Whitworth thread. This thread type has a specific profile angle and pitch suitable for specific applications. The head of the hexagonal head bolt is hexagonal, making it easy to tighten or loosen using wrenches, screwdrivers and other tools. AS 2451 BSW threaded hexagon head bolts are widely used in various machinery, equipment and structures to connect and secure various components. Because of its strong tensile and shear resistance, it is widely used in some demanding applications. Specific specifications and requirements for AS 2451 BSW threaded hex head bolts may vary from country to country. Therefore, when selecting and using, reference should be made to the corresponding standards and specifications to ensure that they meet application needs and safety requirements.

FAQ

1. What is AS 2451 Whitworth thread?

Answer: AS 2451 is an Australian standard that specifies technical requirements and test methods for bolts and other threaded fasteners. Whitworth thread (BSW) is an early British standard thread type, also known as Whitworth thread. It has a specific profile angle and pitch for specific applications.

2. Why choose Whitworth thread?

Answer: Whitworth threads have been widely used historically, especially in some older equipment or specific industries. While modern thread standards such as ISO or DIN may be more advanced in some aspects, Whitworth threads still have their unique advantages in certain specific applications.

3. What are the specifications of bolts?

Answer: Bolt specifications include diameter, length, pitch and other parameters. Specific specifications depend on application requirements, but can generally be found in the AS 2451 standard.

4. How to install and use bolts?

Answer: When installing and using bolts, you need to ensure that the bolts match the nuts or other connecting parts and follow the correct installation steps and torque requirements. During the installation process, you also need to pay attention to keeping the bolts and connections clean to avoid impurities and dirt from affecting the connection performance.

5. What is the anti-corrosion performance of bolts?

Answer: The anti-corrosion performance of bolts depends on their material and surface treatment. For stainless steel bolts, they themselves have good corrosion resistance; for carbon steel bolts, their anti-corrosion properties can be improved through surface treatments such as galvanizing and painting. The specific processing method to choose needs to be decided based on the application environment and requirements.
