Bolts and nuts are basic fastenings essential for assembling machinery, furniture, and equipment. In every circumstance you are using a fastening, you will be required to use the right size. There are different ISO metric sizes for bolts and nuts that help you choose the right one to use in a particular situation.
The “m” before any screw number stands for metric. The numeric number represents the actual diameter size of the screw. The standard size of m8 diameter is 8 mm.
We will look at more detail relating to the m8 screw and how you can differentiate it from other screws. Also, we have a set of different materials that manufacturers use to make crews.
The screw concept
This concept has been there for over 2,000 years: 200 B. C is when this idea started. Since then, the idea has been applied in industries for holding components together and fastening. Without nuts and bolts, many pieces of equipment would fall apart.
Is m8 8mm?
All the nuts and bolts’ dimensions are the measurements of their basic diameter. The “m8” is an approximation of the prime diameter of the threat, which is 8 mm; the actual measurement is slightly less: 7.9mm, whereby the screw’s sharp edges are rounded off.
Is 5/16 The same as m8?
5/6 is close to m8 in terms of dimension. Should the manufacturer make one hair smaller or larger, the 5/6 will become sloppier with a diameter of 8.255mm.
How do I choose a screw size?
The following are simple steps that you should follow when choosing an appropriate screw:
- First, look at the diameter of the material where you are going to place the screw.
- Choose a screw with a thickness that you think will fit well into the material.
- Determine the weight that your screw may support.
- Finally, determine the length of the screw required: length should be based on the material’s depth.
How do you differentiate between m8, m10, and m12 bolts?
Since you already know that “m” stands for metric and the number is the screw diameter size, it is easier for you to understand screw measurements.
You can tell the difference using the following options:
- You may opt to drill holes into the material using an appropriate sized bit that acts as a measuring gauge. Line the three gauges up and sort the appropriate one. This option may not be effective, and sometimes it can be difficult to determine the correct size required.
- Another option available is using a compartment box and thread gauge. This is the easiest option of keeping track. Anyone who uses fasteners ends up with a can of mixed fasteners with little understanding of what’s what. The measuring gauge allows you to measure the diameter of the metric as well as that of standard fasteners. It also gives you more sorting options like determining the length of the and thread pitch of the screw. The best compartment box to use clear one; it allows you to see into the screws. This allows you to see the right one at a glance instead of opening the box looking at what you need.
Factors to consider when choosing materials to make your custom micro screws
You ought to make various significant considerations when choosing the kind of material to use in making screws. The following is what you should consider:
1. The ability to resist corrosion
When selecting a material for making screws, you should check whether screws surroundings are going to be corrosive. If yes, choose high corrosion-resistant materials such as steel. Steel is ideal for making screws that are likely to get exposed to corrosive surroundings.
2. Properties of the material
Some metals tend to be brittle, which makes them easier to scratch and bend. If such materials are used to make screws, screwing and unscrewing them may be difficult. When looking for material for making screws, ensure the material is strong enough to bear damaging forces.
Aesthetics are not as important as the durability and strength of the material. But, in some cases, screws are used in holding decorative components together. In this case, you will need a material that has an attractive appearance. The copper custom screw will appeal more to decorative equipment than steel.
4. Operations of screw fabrication
Always choose a material that can be processed with ease. You should consider the strength of the material to be welded, co-headed, or machined.
5. The cost finished screws
The value of the alloy that is used to make the screws is determined by the factors such as the life expectancy-expectancy of the manufactured screws. A material with a high value ought to match in durability, strength, fabrication needs, costs, mechanical properties, and aesthetics.
6. The material availability
It doesn’t matter how good a material is at making screws; if it is not readily available, it would be of no help to you. In this case, you are less likely to use such material for making screws.
What are screws made of?
There are many kinds of materials that are used to make screws. Yet, some are more preferred and popular than others. Here are a few common screw materials:
This is the most preferred material for manufacturing screws. The reason why steel is quite popular for making screws is, it is readily available and also cheap. Nevertheless, it is weaker compared to other options.
Copper is corrosion-resistant. If a screw has the potential of getting exposed to corrosive conditions, the copper screw will be ideal in such cases.
Aluminium is less durable compared to other materials on the list. The good thing about screws made of aluminium is that they are very light.
If you need screws that are neither too light nor too strong, go for titanium screws. They are a bit expensive, but you can’t dispute their quality.
Screws come in different sizes, and all of them serve the same purpose of holding things together. Screws differ in terms of sizes. The criteria that is used to classify screws is their diameters.
