Customer Questions & Answers
-
Question:
What are 1/4-20 serrated flange hex nuts used for?
Answer: 1/4-20 serrated flange hex nuts are designed for applications that require a secure grip on a threaded rod or bolt. The serrated flange provides a greater surface area, which helps prevent loosening due to vibrations. Commonly used in machinery, automotive, and construction projects, these hex nuts can be particularly effective in providing stability in high-stress environments. -
Question:
What material is used in the production of these hex nuts?
Answer: These serrated flange hex nuts are made from 304 stainless steel, also known as 18/8 stainless steel. This material is popular for its excellent corrosion resistance, making it suitable for both indoor and outdoor applications. The durability of stainless steel helps ensure longevity and performance, especially in moist or harsh environmental conditions. -
Question:
How do I know if these nuts fit my requirements?
Answer: To determine if 1/4-20 serrated flange hex nuts are suitable, check the specifications of your project, particularly the bolt or threaded rod size. The '1/4-20' designation indicates a nominal diameter of 1/4 inch with 20 threads per inch. Ensure that your fastener is compatible in size and thread pitch for optimal performance. -
Question:
Can 304 stainless steel flange nuts withstand high temperatures?
Answer: While 304 stainless steel offers decent heat resistance, it is not recommended for extreme high-temperature applications. It can typically withstand temperatures up to 950°F in continuous service. However, if your project involves elevated temperatures beyond that, considering a specialty alloy designed for high-heat environments may be more appropriate. -
Question:
What advantages do serrated flange nuts have over standard hex nuts?
Answer: Serrated flange nuts feature a toothed surface that helps grip the material they are being fastened to, reducing the likelihood of looseness due to vibrations or shifting. This design offers improved stability compared to standard hex nuts, making them ideal for dynamic applications such as machinery or automotive fastening, where movement is present. -
Question:
Are these hex nuts resistant to rust?
Answer: Yes, being made from 304 stainless steel, these serrated flange hex nuts exhibit excellent resistance to rust and corrosion. This makes them a preferred choice for applications in environments where exposure to moisture or chemicals may occur, ensuring a longer lifespan and consistent performance. -
Question:
What type of threaded rod is compatible with these nuts?
Answer: These serrated flange hex nuts are compatible with UNC coarse thread rods that also have a 1/4-20 size specification. It's essential to match the nut with a 1/4 inch diameter rod that has 20 threads per inch to ensure proper fit and function, allowing for secure fastening in a variety of applications. -
Question:
Do these hex nuts require any special installation tools?
Answer: Standard tools such as a socket wrench or a set of pliers can be used to install 1/4-20 serrated flange hex nuts. No specialized tools are necessary, making them user-friendly for both professional and DIY applications. Ensure the tools are appropriately sized for ease of installation and to prevent damage to the nuts. -
Question:
Where can I buy 1/4-20 (30 Pack) Serrated Flange Hex Nuts in Kenya?

Question:
What is the benefit of buying nuts in a 30-pack?
Answer: Purchasing a 30-pack of 1/4-20 serrated flange hex nuts is economical as it allows you to have enough quantity for multiple projects or repairs.
