1. Description:

We are factory to produce many kinds of screws, bolts with carbon steel and stainless steel for more than 15 years.....


Hexagonal bolts, also known as hexagonal head screws, hexagon head bolts, hexagon head screws, hexagon screws or mechanical bolts, are a common choice in construction and maintenance.Hexagon head bolts, commonly known as hexagon head cap screws, are bolts with hexagonal or six-sided heads.Hexagon bolts have six heads, which is the industry standard for forged head bolts.A common feature of hexagonal head screws is the surface of the gasket directly below the head to produce a better seal.A hexagon head screw bolt is actually produced within a tighter tolerance range and can be used anywhere with a hexagon head bolt.

3. Applications:

Difference between high strength bolts and ordinary bolts:


High strength bolts are larger than common bolts of the same specification.


The material of ordinary bolts is made of Q 235 A 3.


High-strength bolt material 3 steel or other high-quality materials, made after heat treatment, improve the strength.


High strength bolt is made of high strength material. Screw of high strength bolt. Nuts and gaskets are made of high strength steel. 35 CrMoA and other common bolts made of Q235 steel.


From the strength grade point of view: the use of high-strength bolts is becoming more and more extensive. Commonly used 8.8s and 10.9s two grade strength grade, of which 10.9 grade is the majority. Bolt strength grade 10.9. E should be low, generally 4.4. 4.8 grade, grade 5.6 and 8.8.


From the point of view of stress characteristics: high strength bolts apply pretension force and transfer external force through friction. The shear force must be transferred when the nut is tightened when the common bolt is shearing to the hole wall pretension connection. The pretensile force is very small. In addition to the high strength of the material, the high strength bolt will also produce a large pretightening force, resulting in extrusion force between the connectors. The friction force is perpendicular to the screw. The bearing capacity of the high strength bolt is direct.
