Types Of Screw Fasteners - Using The Right Type Of Screws
Well for a lot of tasks we may well find that a nail is the ideal fixing, however when it comes to fasteners then you would be hard pushed to find anything better than a screw.
Investing In The Best Tools
The first thing I would say is that when it comes to using screws, buy an electric screwdriver. Invest in a good one as it will pay for itself many times over, in fact as DIY tools go it is most likely to be the best investment you have ever made.
You may find yourself spending a £100 on one and then only using it twice in three months, but then you will end up doing a big DIY job and wish you had bought two batteries.
When it comes to using screws as fastenings, an electric screwdriver is a Godsend.
Screws can be used to fasten just about any material together other than fastening something to bricks or concrete, in which case you will need a specialist fixing such as a raw plug, to screw in to.
You can buy screws from tiny brass ones suited to fixing wooden cabinets together, through to six inch long screws that could be used to attach a wooden gate to a gate post.
Different Steel Screws
Screw fastenings are commonly made in steel (Either plain steel or stainless steel) or brass. Plain steel screws are ideal for fastening wood together whereby the screws are not exposed to the elements such as rain, as if plain steel screws are used outside then they will rust.
Stainless steel screws are great as a fastener for use outside whereby you do not want the screw to rust if you may need to undo it at anytime. However whilst stainless steel screws may cost more, if you are using screws outside then you would be well advised to use them, as having to drill out a rusted plain steel screw can be a real pain.
Using The Right Type Of Screw
You should always make sure that you get the right fastener for the job. Screws come in a multitude of sizes both in terms of length and width. Whilst they are more expensive than nails, you can tend to utilize them more often, as you can often "Make do" with a screw that is a close size to what you want.
Overall screws are one of the best fasteners that you can buy, and always opt for stainless steel screws if you can afford it.
There are many types of materials for making stainless steel screws, and they can be divided into several categories according to the structure at room temperature: austenitic type: such as 304, 321, 316, 310, etc.; martensite or ferrite type: such as 430, 420, 410 Wait; Austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will result. In this way, 304 stainless steel will have weak magnetic properties. After 304 stainless steel is cold worked, the structure will also be transformed into martensite. The greater the degree of cold working deformation, the more martensite transformation and the greater the magnetic properties of the steel. Like a batch of steel belts, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. Because the bending deformation...
