ASTM A193 Grade B7 Bolts
ASTM A193 B7 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 B7 Hex Bolts and ASTM A193 B7 Hex Head Bolts is some of the toughest fasteners. These ASME SA193 B7 sturdy fasteners are used to connect heavy materials.
Hitesh Steel stock a wide variety of ASTM A193 B7 Long Bolts and ASME SA193 B7 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 B7 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 B7 Bolt used for flanged connections. ASTM A193 B7 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 B7 Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM A193 B7 Nut Bolts are used to attach machine threaded fasteners when joining materials together.
Many of the ASTM A193 B7 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 B7 fastener or large machined fastener? We will manufacture to your specifications and requirements.
