Hexagon head bolt is a kind of commonly used mechanical screw. The utility model has the advantages of easy disassembly and non sliding. Hexagon wrenches are usually 90 degrees long at one end and short at the other. Using short screws to hold the long side can save a lot of force and tighten the screws better. The manufacturing cost of the outer hexagon bolt is much lower than that of the inner hexagon bolt. The advantage is that the outer hexagon bolt is thinner than the inner hexagon bolt (where the wrench is stressed). There are also some hexagon heads that cannot be replaced by the inner hexagon bolt.
In addition, the machine with low cost, low power and low precision requires less inner hexagon bolts than outer hexagon bolts. Hexagon head bolt, also known as hexagon head bolt, is a kind of screw with a hexagonal internal hole on its head. When the inner hole is inserted, the hexagonal wrench can be tightened or loosened. The common hexagon head bolt is a cylindrical head screw, and its head diameter is about 1.5 times of the main diameter of the thread. Other heads include bottom cap screws for attractive surfaces and countersunk screws for tapered threaded holes. The embedded design makes the screw head not exposed to the surface of the fixed object when rotating, so it is usually used for smaller surfaces and places where traditional wrenches are inconvenient to use.
The outer hexagon bolts are divided into inner hexagon bolts and outer hexagon screws, which are generally used to fasten mechanical equipment. Hexagon head bolts are externally threaded fasteners with hexagon heads for wrench rotation. The hexagonal socket bolt is a cylindrical and concave hexagon bolt, and the hexagonal socket screw is a common hexagon head bolt. The hexagonal socket bolt looks like “7″, which is cut into two sections by the hexagonal socket steel and bent into a 90 degree hexagonal socket screw wrench. Hexagon bolts are generally made of stainless steel and form a layer of antioxidant on the surface. After adding molybdenum, the material has good corrosion resistance, wear resistance and rust resistance, and the strength reaches 4.8
In the production of seawater and some chemical media, it is commonly used in general cold chamber processing and wire drawing, with good corrosion resistance. Round stainless steel hexagon head bolts provide excellent corrosion protection even in wet water. There is no residual burr on the surface, and it is not easy to slip when rotating. At the same time, the depth design of the thread is more uniform during use, and the thread teeth are sharper, so as to achieve a firm effect.
