Mild steel fasteners are widely used for all general purposes where high strength and corrosion resistance is not required. Their low cost makes them ideal for everyday use. Mild steel Bolts and Screws confirm to grades 4.6 ,4.8 ,5.6 ,5.8, T0 and 6.8 Nuts to grade 5 & 6.
High-tensile fasteners are strong, durable bolts, screws, and rods made from materials like alloy steel. They are heat-treated to handle high stress and resist fatigue, making them essential for demanding applications. Used in industries like construction, automotive, and energy, these fasteners ensure safety and reliability in critical structures like bridges, turbines, and machinery.
Full threaded stud bolts are non-headed bolts; these are in form of a rod and have threads from end to end. These stud bolts are generally provided with double nuts and often with 4 nuts depending upon the application and requirements of the project or customer. Additionally, washers can also be provided along with these stud bolts. These stud bolts are manufactured by us in carbon steel and stainless steel. Popular carbon steel grades include A 193 and A 320.
A nut is a type of fastener with a threaded hole and are almost always used with a mating bolt to fasten multiple parts together. Hex nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads. Hex is short for hexagon, which means they have six sides. Hex nuts are also known as: Surface finished hex nuts, hex full nuts.
A Heavy nut is a type of fastener with a threaded hole. Nuts are almost always used with a mating bolt to fasten multiple parts together. Heavy Hex Nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads.
A washer is a thin plate with a hole that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Washer, machine component that is used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area. For load distribution, thin flat rings of soft steel are usual.
Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. Locking?washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device.
HT washers are generally used for critical application and are used with HT bolts & nuts. It is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Washer, machine component that is?used in?conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area. For load distribution, thin flat rings of soft steel are usual.
Chamfered washer also known as a Through Hardened?washer. Used with high strength friction grip / preloaded bolting assemblies. Designed to stop the bolt head or nut embedding into the material being clamped or deforming when under load instead distributing the force onto the material over a wider area.
Foundation bolts are used in pre-engineered Building, transmission line, Railway, wind turbine foundations and construction. These Foundation Bolts are available in different variety & of types including Full threaded & partial threaded.
