Choose the Best Bolts for Your Business Instruments

The ASTM A193 standards apply to alloy and stainless steel anchor bolts for pressure vessels, valves, flanges, and fittings used in high temperature, high pressure, or other special applications.

Many grades are covered, including ferrite and austenitic stainless steel designated as B5, B6, B7, Grade 8.8 Bolts, B8M, Grade 12.9 Bolts and more. The choice depends on the design, conditions of use, mechanical properties, and high-temperature properties. These specifications are expressed in inches, pounds, and SI units. Unless the purchase order or contract specifies applicable A193M specifications (SI units), inch-pound units apply.
