Bolts, Nut Size, Strength Grade, Torque Table

Currently we offer screws fastener incarbon steel (low carbon steel, medium carbon steel, alloy steel), stainless steel, copper. Each material has unique advantages relating to mechanical performance, weight, corrosion resistance and more. There are also economic costs to consider, using the correct material is critical to the success of your project, so our engineers are happy to advise you on the best materials for your application and budget, We will always advise our customers on the machinability of any material requested, screws fastener at our facilities are listed in the below table. The basic strength grade of the screw fastening is as follows:

Steel structure with the nut performance grade points 3.6,4.6,4.8,5.6,6.8,8.8,9.8,10.9,12.9 and so on more than 10 grades, of which 8.8 and above the nut material for the low carbon alloy steel or medium carbon steel and heat treatment (Quenching, tempering), commonly known as high-strength nut, the rest known as ordinary nut.
