Stainless Steel Bolt ASME A194 B8 B8m M27 Hexagonal Nut

First introduced in 1936, this specification is widely used in the petroleum and chemical industries. ASME A194 covers both inch and metric fasteners. The standard outlines requirements for alloy steel and stainless steel bolting materials used in high-temperature or high-pressure environments. It applies to fasteners used in pressure vessels, valves, flanges, and fittings. While UNC threads are commonly available, for diameters above one inch, 8 threads per inch (TPI) are typically specified.
