ASTM F837 is a Standard Specification for Stainless Steel Socket Head Cap Screws

ASTM F837 specification covers stainless steel metric socket head cap screws (SHCS) intended for use in applications requiring general corrosion resistance. Two groups of stainless steel alloys are covered, austenitic Grade A1 and martensitic Grade C1. Four property classes are covered: austenitic A1-50 in an annealed condition; austenitic A1-55 in a cold worked condition; austenitic A1-70 in a cold worked condition, and martensitic C1-110 in a heat treated condition. Materials shall be tested and the individual grades shall conform to forging; threads; heat treatment; chemical composition; mechanical properties such as thread diameter, tensile strength, yield strength, elongation, core hardness (Vickers and Rockwell); and corrosion resistance values. Workmanship, finish, and appearance are also detailed. ASTM F837-13e1, Standard Specification for Stainless Steel Socket Head Cap Screws. ASTM F837 Bolts

ASTM F837 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 F837 Hex Bolts and ASTM F837 Hex Head Bolts is some of the toughest fasteners. These ASME SF837 sturdy fasteners are used to connect heavy materials.

Steel Tubes India is a leading manufacturer & stockist of ASTM F837 Long Bolts and ASME SF837 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 F837 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 F837 Bolt used for flanged connections. ASTM F837 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 F837 Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM F837 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 F837 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 F837 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).
