ASTM A320 L43 specification covers alloy steel bolting materials such as rolled, forged, or strain hardened bars, bolts, screws, studs, and stud bolts for pressure vessels, valves, flanges, and fittings for low-temperature service. Each alloy shall conform to the prescribed chemical composition requirements. ASTM A320 material, as represented by the tension specimens, shall conform to the requirements as to tensile properties such as tensile strength, yield strength, elongation, and hardness. SA320 material shall meet the prescribed impact energy absorption requirements and the recommended test temperature. Mechanical tests shall be conducted on the material, namely: impact testing, tension testing, and hardness testing.

ASTM A320 L43 Bolts

ASTM A320 L43 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 A320 L43 Hex Bolts and ASTM A320 L43 Hex Head Bolts is some of the toughest fasteners. These ASME SA320 L43 sturdy fasteners are used to connect heavy materials.

Hitesh Steel stock a wide variety of ASTM A320 L43 Long Bolts and ASME SA320 L43 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 A320 L43 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 A320 L43 Bolt used for flanged connections. ASTM A320 L43 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 A320 L43 Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM A320 L43 Nut Bolts are used to attach machine threaded fasteners when joining materials together.

Many of the ASTM A320 L43 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 A320 L43 fastener or large machined fastener?  We will manufacture to your specifications and requirements.
