ASTM A193 specification covers alloy steel and stainless steel bolting material for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications.Several grades are covered, including ferritic steels and austenitic stainless steels designated ASTM A193 B5, B8, B8M and so forth. ASTM A193 Material according to ASTM A193 B8M 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. ASTM A193, Grade B8M Class 1 Stainless steel, AISI 316, carbide solution treated. Stainless steel, AISI 316, carbide solution treated.

ASME SA193 B8 (304SS) / B8M (316SS) Class 2 (Class II) stainless steel studs and bolts are used in applications where standard (class 1) bolting is not acceptable. ASTM A193 Class II bolts allow those same flanges to be used with the same gaskets, but because they are stronger, they do not require the flange to be tightened as much.

ASTM A193 B8M Bolts

ASTM A193 B8M bolts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. ASTM A193 B8M Hex Bolts and ASTM A193 B8M Hex Head Bolts is some of the toughest fasteners. These ASME SA193 B8M sturdy fasteners are used to connect heavy materials.

Hitesh Steel stock a wide variety of ASTM A193 B8M Long Bolts and ASME SA193 B8M 12 Point Bolts in India. There are hundreds of combinations of materials, heads, threads, plating, heat treating, and secondary operations. We are manufacturer & supplier of ASTM A193 B8M studs such as All-Thread, Tap-End, Double-End Studs, and Combination Studs, different types of nuts such as Hex Nuts, Heavy Hex Nuts, Overtapped Nuts, Tommy Hole Nuts, Spherical-Faced Nuts and Full Threaded Rods, full thread rods, bonnet bolts, Carriage Bolt in a variety of finishes and sizes from 1/2" to 3 1/2". In the petroleum and chemical industry the fully threaded stud is the most common ASTM A193 B8M Bolt used for flanged connections. ASTM A193 B8M Stud bolts are available in all thread pitches (UNC/UNRC – UNF/UNRF – 8UN) diameters and metric sizes. Hitesh Steel has the capability to thread and manufacture specials from round bar to the customers drawings.

ASTM A193 B8M Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM A193 B8M Nut Bolts are used to attach machine threaded fasteners when joining materials together.

Many of the ASTM A193 B8M Flange Bolts we manufacture for more critical high specification Superalloys. Whilst we manufacture many of the non-favoured thread forms such as BSW BSF UNC & UNF, we are finding the biggest call is now for Metric Hexagon Bolts that are modified versions of existing international standards or indeed custom bespoke bolting manufactured to Customer or OEM Drawings.

Is your requirement for a small ASTM A193 B8M fastener or large machined fastener?  We will manufacture to your specifications and requirements.
