ASTM F3125 / F3125M – 15a

ASTM F3125 is a Standard Specification for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions. This specification is a consolidation of and replacement for six ASTM standards: A325, A325M, A490, A490M, F1852 and F2280.

ASTM F3125 Bolts

ASTM F3125 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 F3125 Hex Bolts and ASTM F3125 Hex Head Bolts is some of the toughest fasteners. These ASME SF3125 sturdy fasteners are used to connect heavy materials.

Nirmaan Steel is a leading manufacturer & stockist of ASTM F3125 Long Bolts and ASME SF3125 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 F3125 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 F3125 Bolt used for flanged connections. ASTM F3125 Stud bolts are available in all thread pitches (UNC/UNRC – UNF/UNRF – 8UN) diameters and metric sizes. Nirmaan Steel has the capability to thread and manufacture specials from round bar to the customers drawings.

ASTM F3125 Hex Cap Screws– also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM F3125 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 F3125 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 F3125 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).
