Stainless steel hexagonal bolts include hexagonal head bolts (partially threaded), hexagonal head bolts (fully threaded), also known as hexagonal head bolts (rough), rough hexagonal head bolts, and black iron screws. It belongs to one of the common types of stainless steel bolts, in addition to internal hexagonal bolts, external hexagonal bolts, non-standard bolts, and so on. Due to the characteristics of stainless steel, stainless steel bolts have higher tensile strength, rust resistance, and aesthetic appeal compared to ordinary carbon steel bolts.
Stainless steel hexagonal bolts are not strictly equipped with torque wrenches during assembly, and most people are not familiar with the specific tightening torque. They believe that the tighter the tightening, the better to tighten the connecting rod hexagonal bolt. Using a longer force rod, the tightening torque is too large, exceeding the yield limit of the stainless steel hexagonal bolt material, causing the connecting…
