How Do You Specify Stainless Steel Bolts?
When specifying stainless steel bolts, several key factors need to be considered.
First, determine the diameter. This is crucial as it affects the load - bearing capacity. It should be selected based on the specific application requirements to ensure the bolt can handle the forces exerted.
The length of the bolt is another important aspect. Measure the thickness of the materials to be joined and add appropriate allowance for proper engagement and tightening.
Thread type and pitch are significant. Coarse or fine threads may be chosen depending on the application. Fine threads offer more holding power in some cases, while coarse threads are better for quick assembly in certain environments.
The grade of stainless steel is vital. Different grades have different corrosion - resistance properties and strength levels. For example, 304 stainless steel is commonly used in general - purpose applications with moderate corrosion resistance, while 316 stainless steel is preferred for more corrosive environments like marine applications.
Also, consider the head type. Options include hex heads, round heads, flat heads, etc. The choice depends on the design and accessibility for tightening tools.
Finally, surface finish might be specified in some cases. A smooth or polished finish can be desired for aesthetic reasons or to improve corrosion resistance further. By carefully considering these elements, you can accurately specify the right stainless steel bolts for your project.
