From the point of view of stress characteristics: high-strength bolts exert pretension and transmit external force by friction. The shear force of ordinary bolt connection is transmitted by the shear resistance of bolt rod and the pressure of hole wall. The pre pressure produced when tightening the nut is very small and its influence can be ignored. In addition to the high material strength of high-strength bolt, a large pre pressure is also exerted on the bolt to make the connection members produce extrusion pressure, so that there is great friction force perpendicular to the screw direction, and the pre pressure, anti slip coefficient and steel All kinds of materials directly affect the bearing capacity of high-strength bolts.

In terms of strength grade, high strength bolts are increasingly used. Common 8.8s and 10.9s Two strength levels, where ten point nine Grade is the most. The strength grade of ordinary bolt is lower, generally Four point four Class Four point eight Class Five point six Grade and Eight point eight Class.

High strength bolts are made of high strength materials. The screw, nut and washer of high-strength bolt are made of high-strength steel, commonly used 45 steel, 40 boron steel, 20 manganese titanium boron steel, 35CrMoA, etc. Ordinary bolts are usually made of Q235 (equivalent to A3) steel.
