Sourcing of Class 4.6 bolts

[bagel_68]

Hi all

We have been sourcing Class 4.6 bolts of the following specifications :

1. Acceptable fastener standards: ISO4762 (Cap Heads), ISO4014 (Hexagonal Head), etc
2. Mechanical properties: ISO 898-1:2013 especially Table 2 and 3 with impact energy of at least 27 J tested at – 20 degC or at least 40 J tested at room temperature

However, we have difficulty sourcing these bolts in good quality. Previously, we have bought some bolts but they showed poor performance in elongation and impact tests.

As such, we would appreciate it if any of you could advise any source that we can purchase these Class 4.6 bolts in good quality. Thank you very much.

Hello,

Thank you for reaching out to the forum with your question. I have experience in sourcing quality materials for various projects and I understand the importance of finding reliable suppliers.

Based on the specifications you have provided, I would recommend looking into suppliers that specialize in fasteners and have a strong reputation for providing high-quality products. It may also be helpful to specifically request for bolts that meet the ISO4762 and ISO4014 standards, as this will ensure that the bolts are manufactured to the required specifications.

In addition, I would suggest reaching out to multiple suppliers and requesting for samples to conduct your own performance tests. This will give you a better understanding of the quality of the bolts and help you make an informed decision.

Finally, I would also recommend considering the possibility of custom ordering the bolts from a reputable manufacturer. This may ensure that the bolts are specifically made to meet your desired specifications and quality standards.

I hope this helps and wish you all the best in finding a reliable source for Class 4.6 bolts. If you have any further questions, please do not hesitate to reach out.
