Characteristic PRODUCTS
Q235 wire is commonly used for hex screws, and of course, iron screw wire is also used. The wire used for these screws can determine some of the characteristics of hex screws.
The first one is that the hardness of stainless steel screws is relatively high, but if it is made of iron, the hardness is significantly worse, which is related to the wire of the iron itself. The texture of iron itself belongs to a relatively soft category, which cannot be compared to stainless steel wire.
However, in order to achieve the required hardness for iron screws, heat treatment is generally used to harden them. During the heat treatment process, it is necessary to ensure that the screws are uniformly heated. Otherwise, not only will the hardness of the screws not meet the requirements, but it will also make them easy to bend, greatly increasing the production cost of hexagonal screws. After heat treatment, it is possible to increase the hardness of iron hexagonal screws, but due to wire issues, it is still not possible to compare the quality with stainless steel wire.
One thing to note for hex screws is to try not to let the screw head slip during use, otherwise it will be difficult to remove the screw in the future.
How to use bolts USE
Excellent Tightening & Anti-Loosening Effect
After the installation of the internal hexagonal bolt, the tightening effect is very good due to the tightening of the thread, and there will be no loosening of the bolt, which can effectively avoid the loosening problem caused by long-term vibration and vibration of mechanical equipment. At the same time, hexagonal bolts can also be used with locking washers, locking agents, and other auxiliary measures to prevent loosening, resulting in higher reliability.
Easy to Install
During the installation process of the internal hexagonal bolt, only the internal hexagonal wrench is needed for operation, which is simple and convenient, reducing manual operation time and cost. Compared with other bolts, hexagonal bolts are less prone to damage during installation, can be reused, and have a longer service life.
Wide Applicability
The biggest advantage of hexagonal bolts is that they have a wide range of applications. It can be applied to various industries and fields, including the automotive industry, aerospace, mechanical manufacturing, construction engineering, etc. During the manufacturing, installation, and maintenance processes, hexagonal bolts have also demonstrated excellent performance and reliability.
In summary, as one of the commonly used fasteners in mechanical equipment, internal hexagonal bolts have the advantages of high strength, good anti loosening effect, easy installation, and wide applicability, making them a very reliable fastener.
Frequently Asked Questions FAQ
What materials are commonly used to manufacture hex screws?
Q235 wire is commonly used for hex screws. Additionally, iron screw wire and stainless steel wire are also frequently used depending on the required hardness and application.
How does the hardness of iron hex screws compare to stainless steel screws?
Stainless steel screws naturally possess a higher hardness. Iron screws are softer by nature, so they must undergo heat treatment to achieve the required hardness, though they still may not match the quality of stainless steel.
What precautions should be taken when using hex screws?
It is crucial to avoid letting the screw head slip during installation or removal. If the head slips, it will become very difficult to remove the screw in the future.
Why do internal hexagonal bolts offer excellent anti-loosening effects?
The tight thread engagement ensures a strong hold that resists loosening from long-term vibration in mechanical equipment. Their reliability can be further enhanced by using locking washers or locking agents.
What tool is required to install internal hexagonal bolts?
Only an internal hexagonal wrench (Allen wrench) is needed for operation, making installation quick, convenient, and cost-effective.
What industries commonly use hexagonal bolts?
They are widely applied across various fields, including the automotive industry, aerospace, mechanical manufacturing, and construction engineering.
