carries a complete line of 8.8 Galvanised Bolts, 8.8 Stainless Steel Bolts in mumbai, India

Often, the Din 933 Grade 8.8 Standard is referred to as the structural grade for bolts.The specification Bs 3692 Grade 8.8 standard fasteners are manufactured using medium carbon steel. This medium carbon steel has been treated to heat by both quenching and tempering.  While medium carbon steel grades are cheaper and have good ductile and malleable qualities, as an alloy they tend to have lower tensile strength.

The hardness of the medium carbon steel Metric Grade 8.8 can be increased by heat treating them. Heat treating the En 15048 Grade 8.8 leads  to a change in the mechanical fasteners. For instance, the  Class 8.8 Bolts have an increased hardness, ductility, yield strength, and impact resistance.

Heat treated Grade 8.8 Bolt is known to exhibit good tensile strength and perform well in most environments. Therefore these fasteners are found in motors, engines, railroad equipment and processing equipment. One drawback about the 8.8 Bolt Material is their underperformance in extreme temperature environments.

One of the main characteristics of the 8.8 High Tensile Bolts are the galvanised hexagon heads. These heads are either made with zinc or are plated with zinc. The En 15048 Bolt can be coated, plated or finished as required by the customer or by the product end use.Identification of the 8.8 Stainless Steel Bolts is easy as the fasteners are often stamped with an ‘8.8’ or they have a set of 3 radial lines on the head of the 8.8 Galvanised Bolts.
