The hot-dip galvanized hexagon screw is to place the bolt in the high-temperature zinc solution of 600 ℃ so that its surface is coated with a dark gray surface. The advantages of hot-dip galvanized hexagon screw are strong adhesion of zinc coating, thick coating and strong corrosion resistance. Hot dip galvanized bolts are used for [...]
Production process of high strength black bolt: Rack mounting → oil removal by boiling alkali solution → water cleaning → rust removal by hydrochloric acid solution → water cleaning → boiling water heating → oxidation → water cleaning → saponification → water cleaning → self drying → hot oil soaking → oil control → inspection [...]
Dacromet hexagon bolt has many advantages, which are listed as follows: Ultra strong corrosion resistance: the thickness of Dacromet hexagon bolt film is only 4-8 μ m, but its antirust effect is more than 7-10 times of that of traditional galvanizing, hot galvanizing or coating. The standard parts and pipe joints treated by Dacromet process [...]
The overlong bolt is usually constructed by the torque axial force method, which is divided into two stages of initial tightening and final tightening. The torque coefficient refers to the coefficient between the torque and the axial force of the bolt in the tightening process. Generally speaking, it has a great relationship with the friction [...]
From the following three aspects, the difference between high strength hexagon bolt and ordinary bolts is introduced. In terms of strength grade High strength hexagon bolts are widely used. The strength grades of 8.8s and 10.9s are commonly used, of which 10.9 is the most. The strength grade of ordinary bolts is lower, generally 4.4, [...]
As a small hardware component, high strength hexagon socket bolt is widely used, ranging from a small electronic product and mechanical equipment to automobiles, airplanes, ships, etc., which need to move to high-strength hexagon bolts. In addition, the high-strength hexagon bolt is applied to the following industries: electronic industry, electrical industry, electrical industry, power industry, [...]
In the work, we can often see the hot dip galvanized hexagon bolt, because it has many advantages, making it popular with customers, and rapid development in the market. Generally speaking, the top surface of the head of the hot-dip galvanized hexagon bolt is marked with convex or concave characters, or the side of the [...]
The High Strength Hexagon Socket Bolts connection is to clamp the plates of the connecting plate by a large amount of tightening pre tension in the bolt bar, which is enough to produce a great friction force, so as to improve the integrity and rigidity of the connection. When subjected to shear force, according to [...]
The Steel Structure Bolt thread refers to a kind of uniform helix bulge on the screw or bolt surface or the section of the internal surface, which mainly plays the role of connection, adjustment, transfer movement, etc. Generally speaking, the thread of steel structure bolt can be divided into three types according to the structural [...]
What are the installation points of high strength hexagon bolt? Let's make a list: 1. During the assembly of high-strength hexagon socket bolt connection pair, the side with round table of nut shall face the side with chamfering of washer. For the assembly of large hexagon head and high-strength hexagon bolt connection pair, the chamfered [...]
Calculation and Drawing of Hexagon Bolt: Hexagon bolt is a very common bolt, which is widely used. It can fasten connected parts by bolts, nuts and washers. The function of the ring is to prevent the surface of the connected part from being damaged when tightening the nut, and to make the pressure of the [...]
Is it necessary to use gasket when connecting heavy hex bolts? The gasket of heavy hex bolts is mainly used to avoid the scratch of bolt and reduce the bending force. Whether to use washers or not depends on the specification of heavy hex bolts. When the bolt assembly hole is too large, a washer [...]
