The term "expansion bolts" is thrown around quite frequently; however, what exactly is the function of expansion bolts? The expansion bolt is a specialized type of threaded connection that is used to fasten the bracket or the piece of equipment to the wall or the floor. In most cases, the principle of fastening is accomplished through the application of the principle of friction generated by expansion. When the expansion bolt is inserted into the hole, the metal sleeve of the bolt expands to fill the entirety of the hole. This can serve as a very effective form of fastening!
There are many applications for expansion bolts, particularly in the construction industry, including the installation of mechanical equipment, air conditioning shelves, stainless steel doors and windows, crystal lamps, swings, and other similar applications. There are many different kinds of expansion bolts, including plastic expansion, countersunk head expansion, expansion hook, and stainless steel expansion. Stainless steel expansion bolts expansion can be subdivided into external expansion and internal expansion, as well as various kinds of expansion that are used for a variety of purposes.
So the question is, under what conditions and with what kind of inflation should one work? Visit a local hardware store to purchase expansion screws; what size and thread count should I look for? It will save you a lot of time if you take the time to compile the following table, which details the circumstances under which different types of screws should be purchased. The market primarily contains these types of expansion screws at the moment, and we have provided a rundown of both their technical specifications and the situations in which they can be used.
Bolts made of plastic that expand.
A plastic expansion of this kind is analogous to the replacement of traditional wooden deeds. The 6x30 and 8x40 formats are the most common models. These two models are typically utilized for pendants in the kitchen and the bathroom, including but not limited to towel hanging rods, knife hanging rods, hanging cross stitches, and other similar items. The lengthened versions of the 8x60, 8x80, and 10x100, as well as the 10x80 and 10x100, are most commonly used for hanging heavy objects like LCD TVs, range hoods, and other similar items.
Bolts made of stainless steel used for expansion
When working with expansion bolts made of stainless steel, it is necessary to choose a specific expansion bolt to use for each unique circumstance presented by the wall. It can primarily be broken down into two categories: internal expansion and external expansion. The primary distinction between the two types of expansion is that, once the external expansion has been installed, the screw rod will be visible outside, whereas the screw rod for the internal expansion will be hidden inside the wall. In the realm of home improvement, one of the expansion bolts that sees the most use is the external expansion variety. The M6, M8, M10, and M12 are the ones that are seen most frequently. In theory, the greater the force, the longer the arm that is used to apply it. Long, your choice tamper proof screws should be based on the current circumstances. The inner expansion bolts made of stainless steel are most commonly utilized for the purpose of fastening crystal lamps, anti-theft windows, air conditioners, swings, stair handrails, and other similar items, in addition to some other applications in which exposed screws are not required.
Internal expansion can also refer to the use of bolts made of stainless steel with countersunk heads for expansion. In order to properly install this kind of installation, the surface of the fixed object needs to have a hole with a countersunk head punched into it. After being installed, the head of the screw is even with the surrounding surface. The majority of their applications are in installation, such as guide rails.
In general, there are four different specifications, which are as follows: 6*60, 6*80, 6*120, and 6*150.
6*60: The total length is 60mm, the casing length is 45mm, the diameter is 8mm, the wall thickness is 0.7mm, and the surface is color-plated zinc; Zinc; octagonal nut with 10mm outer diameter, 5mm thickness, and white zinc plated surface; gasket with 13mm outer diameter, 1mm thickness, 6mm inner diameter, and white zinc plated surface; ring with 9mm outer diameter, 6mm inner diameter, and 1.6mm thickness; total
6*80 has a total length of 80mm, a casing length of 65mm, a diameter of 8mm, a wall thickness of 0.7mm, and is plated with color zinc on the surface; the screw length, nut, gasket, and shrapnel are the same as those described above.
6*120: The total length is 120mm, the casing length is 105mm, the diameter is 8mm, the wall thickness is 0.7mm, and the surface is plated with color zinc; the screw length, nut, gasket, and shrapnel are the same as above. 6*120: The total length is 120mm, the casing length is 105mm, the diameter is 8mm, the wall thickness is 0.7mm, and the surface is plated with color zinc.
6*150: The total length is 150mm, the casing length is 135mm, the diameter is 8mm, the wall thickness is 0.7mm, and the surface is plated with color zinc one way screws; the screw length, nut, gasket, and shrapnel are the same as above. 6*150: The total length is 150mm, the casing length is 135mm, the diameter is 8mm, the wall thickness is 0.7mm, and the surface is plated with color zinc.
hook for expansion made of stainless steel
The expansion hook made of stainless steel can be used for a wide variety of purposes. Either vertically or horizontally, it can be used to hang things like bird cages and lanterns from the top of the structure. There are many anti-falling nets installed in manholes, and when it is installed in the wall, it can be used as a clothesline. There are four different specifications, labeled M6, M8, M10, and M12, and the single load can be 100 kg, 120 kg, 200 kg, or 300 kg.
The information regarding expansion bolts that was presented earlier was compiled by Xiaobian. I really hope that it can be of some use to you in actual practice. In a nutshell, expansion bolts can be thought of as a type of application screw that is relatively robust.
