What are the properties of stainless steel hex bolts

The stainless steel hex bolts include hex head bolts (partial threads), hex head bolts (full threads), hex head bolts (crude), hex head cap screws, and black iron screws. It is one of the common types of stainless steel bolts, as well as hexagon socket bolts, non-standard bolts, and so on. Because of the characteristics of stainless steel, stainless steel bolts have the characteristics of tensile resistance, rust-proof appearance, etc. compared with ordinary carbon steel bolts. Stainless steel hexagon bolts are not equipped with torque wrenches in the assembly. Most people do not understand the specific tightening torques. They think that the tighter the better; the longer bolts are used to tighten the connecting rod hexagon bolts and the tightening torque is too large. Exceeded the yield limit of stainless steel hexagonal bolts, resulting in yield deformation of the connecting rod hex bolts, reducing the service life of stainless steel hex bolts. Failure of the fastener causes it to break due to excessive elongation under the action of an impact load, and safety accidents are likely to occur. It should be emphasized that the hexagonal bolts of the connecting rod must be tightened according to the standard. Do not think that the tighter the bigger the better.
