Choosing the right stainless steel bolts for your application can be tricky. There are a few important factors to consider when selecting the right bolt, such as grade and material type. Keep reading to learn more about choosing the right stainless steel bolt for your application.
Grade and Material Type
The grade and material type you choose will depend on the purpose of the bolt and the environment in which it must operate. All types of Stainless Steel Bolts are not created equal. Each type has unique properties that make it better suited for certain applications.
Generally speaking, there are two main grades of stainless steel bolts – 304 and 316. Grade 304 is a general-purpose grade that is corrosion-resistant and ideal for outdoor use. In contrast, grade 316 is a higher-grade stainless steel with superior resistance to extreme temperatures, pressure, saltwater, or other corrosive environments.
Threads of Stainless Steel Bolts
When selecting a stainless steel bolt, you should also consider threading options. The threading options available will vary depending on the size of the bolts you need. Threads can be coarse or fine threads, with coarse being more commonly used in larger-diameter bolts and fine in smaller-diameter bolts. Threads may also come in either full-thread or half-thread options. People commonly use the full thread with small-diameter screws, while they typically reserve the half-thread for larger screws. Additionally, some bolts may have rolled threads rather than cut threads. These provide superior strength but at the cost of reduced flexibility compared to cut threads.
Head Styles Stainless Steel Bolts
Finally, you should consider head style when choosing a stainless steel bolt for your application. In most applications, flat or hex heads refer to how the bolt’s head sits above or flush with whatever surface it is mounted on. Mounting purposes require a greater surface area offered by flat heads. But they must be countersunk into whatever surface they are mounted on. Hex heads provide greater strength but do not require any countersinking and provide less surface area for mounting purposes than flat heads.
Key Takeaway: When choosing a stainless steel bolt for your application, there are several factors to consider, including grade and material type, threads, and head style. Selecting the appropriate stainless steel bolt carefully can help ensure you have exactly what you need without unnecessarily having extra hardware take up space. Grade 304 is best for outdoor use, while grade 316 offers superior resistance to extreme temperatures and corrosive environments.
