Stainless Steel ASME A194 B8 B8m Hexagonal Nut with Bolt
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. A194/A194M covers both inch and metric series products. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure 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 8Â threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A194 covers a number of other standard specifications not covered in this description including B5, B6, and B16.
