ASTM A574 - 17

Standard Specification for Alloy Steel Socket-Head Cap Screws

ASTM A574 specification covers the requirements for quenched and tempered alloy steel socket-head cap screws. ASTM A574 screws shall be fabricated from steel made to fine grain practice and shall be alloy steel conforming to the chemical composition specified. Different tests shall be conducted in order to determine the following mechanical properties of screws: tensile or wedge strength, proof load, yield strength, elongation, Rockwell hardness, and Vickers hardness.

ASTM A574 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 A574 Hex Bolts and ASTM A574 Hex Head Bolts is some of the toughest fasteners. These ASME SA574 sturdy fasteners are used to connect heavy materials.

Steel Tubes India is a leading manufacturer & stockist of ASTM A574 Long Bolts and ASME SA574 12 Point Bolts in India. Bolts are externally threaded fasteners used in industrial and construction applications for assembling two unthreaded products together and available in hundreds of combinations of materials, heads, threads, plating, heat treating, and secondary operations. We are manufacturer & supplier of ASTM A574 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 A574 Bolt used for flanged connections. ASTM A574 Stud bolts are available in all thread pitches (UNC/UNRC – UNF/UNRF – 8UN) diameters and metric sizes. Steel Tubes India has the capability to thread and manufacture specials from round bar to the customers drawings.

ASTM A574 Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM A574 Nut Bolts Hex Bolts, Tab Bolts, Flange Bolts, Carriage Bolts, Shoulder Bolts and T Head Bolts are used to attach machine threaded fasteners when joining materials together.

Many of the ASTM A574 Flange Bolts We produce for more critical high specification Superalloys in our Mumbai Factory. We also manufacture a wide range 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 A574 fastener or large machined fastener? We will manufacture to your specifications and requirements. These Bolts can range in inch sizes from 1/4-20 through 1-8 (coarse thread) and 1/4-28 through 1-14 (fine thread). Bolts can range in metric sizes from M6-1.0 through M24-3 (coarse thread) and M6-0.75 through M24-1.5 (fine thread).
