A2 70 Bolt is classification of high tensile bolts. Viha Steel & Forging is a leading manufacturer and supplier of the different types of bolts such as the A2 70 Hex Head Bolt. The nomenclature is based on the minimum tensile strength of the bolt. The bolts have 700Mpa minimum tensile strength and they are called the A2 70 Hex Bolt. There are other classes which correspond to their respective minimum tensile strength values.

The applications of these high tensile bolts include construction, machinery, oil and gas and many other industrial applications. The A2-70 Stainless Steel Bolt can come in various shapes, structures and dimensions. The material used for this class of steel bolts is the 304 austenitic stainless steel. The Stainless Steel Bolt Grade A2-70 is cost effective, strong, hard and general corrosion resistant as well.

The size of the bolts range from ¼ inches to 24 inches and these bolts are used in different application needs. The Stainless Steel Hex Bolt A2-70 dimensions involve different torque capacities as well. The smaller ones such as the M4 sizes have about 2.7Nm torque while the larger ones have larger torque values. The a2-70 allen bolt is a special head bolt that can take an allen key in for tightening.
