ASTM A193
Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

These Ohuhu 2 Stainless Steel Polish Mirror License Plate Frame + Chrome Screw Caps are a very nice looking set of license plate frames. They are made of stainless steel so they hold up well to the elements without rusting. The shiny surface is easy to wipe clean when necessary. The polished surface looks great on my car and these hold the license plate very well. The screws, washers and screw caps are included along with the frame so you can put these on your car right away. I wasn’t sure if it was just me but I had a little trouble getting the screws in at first, but did get them in after a bit. I love the looks of them on my car, and would recommend them to others.
