ASTM A449 - 14

ASTM A449 is a Standard Specification for Hex Cap Screws, Bolts and Studs, Steel, Heat Treated, 120/105/90 ksi Minimum Tensile Strength, General Use

ASTM A449 specification covers quenched and tempered steel hex cap screws, bolts, headed bolts, rods, and anchor bolts in diameters ranging from 1/4" through 3" inclusive and studs having a minimum tensile strength. The fasteners are intended for general engineering use. Type 1 fasteners shall be plain carbon steel, carbon boron steel, alloy steel, or alloy boron steels conforming to the requirements. Type 3 fasteners shall be weathering steel and shall conform to one of the chemical compositions specified. Tensile strength, proof load, hardness tests, and axial tension tests shall be performed to conform with the specified requirements.

ASTM A449 Bolts

ASTM A449 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 A449 Hex Bolts and ASTM A449 Hex Head Bolts is some of the toughest fasteners. These ASME SA449 sturdy fasteners are used to connect heavy materials.

We are manufacturer & supplier of ASTM A449 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 A449 Bolt used for flanged connections. ASTM A449 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 A449 Hex Cap Screws- also known as machine bolts or hex bolts are available in various bolt grade markings and strengths. Our ASTM A449 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 A449 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 A449 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).
