DIN931 / DIN933 Heavy Hex Head Bolts For Electric Power Tower
Description:
A hex cap screw is a screw with a hex head, which is known to all as hex head bolt.
Some data show that the strength at the thread of a small number of 8.8-grade high-strength bolts is lower than the standard requirements after hot-dip galvanization, and the strength at the thread of the majority of the bolts above 9.8-grade cannot meet the requirements after hot-dip galvanization.The process has poor working environment and serious pollution.Many of us have heard of the product of carriage screw, after all, although this kind of screw is less used in our life, but it is in each of us
The use of this kind of equipment is indeed quite common, and when our carriage screw factory produces this kind of product, it will take it into consideration for our industry
The mechanical function may be more, so the function of this product may be more in this aspect.First our carriage screws in
It is usually used to connect two objects, and it is usually used in conjunction with our light hole and our nut, and I
Our carriage screw factory also takes this into consideration, so our products cannot be connected if they are used individually.And in the
When it is installed, it may also need the help of a variety of tools, generally speaking, the main use is the wrench, and the main application of the wrench.Cold drawing, cold upsetting or hot forging, stress removal annealing and hot galvanizing are important forming processes for tower bolts. In this paper, the relationship between 6.8 class tower bolt forming process and residual stress distribution in the subsurface layer of the polished bolt rod was studied, as well as the appearance features and corrosion resistance of hot Zn and zn-5al coating layers at different temperatures.The effects of stress removal annealing and hot dip galvanizing on the surface residual stress of cold heading bolt and hot forging bolt were compared.By OM, SEM, EDS, X-ray residual stress analyzer and electropolishing instrument, the distribution of residual stress at different depths of the subsurface layer of 6.8 tower bolt polished rod was studied.

Application:
Hexagonal bolts connect two parts.
This connection type called bolt connection. As to unscrew the nuts from the bolts, so that the two parts can be separated, so bolting belongs detachable connection.
The hex head bolts are be used in connecting.
