Special Screws

Special screws are all screws that are not found in the usual fastening technology. Special screws can be found in many special applications.

Special screws, what all falls under this term? Certainly more and more of you are asking yourselves what exactly are special screws and why are such screws mainly used in mechanical engineering? Yes, a tricky question? Because in order to shed more light on this question, you would have to clarify exactly which types of screws would fall under this cover of special screws. We will try to shed some more light on the dark chapter of this generic term. When people search the Internet for the search term special screws made of metal, i.e. steel or stainless steel, they are exclusively searching to find a specific type of screw from a large family of screw connections. This could be extremely difficult, among others, because this group of screws includes all those screws that are not standard in today's fastening technology. But how must or can special screws be constructed or for which purposes are they mainly used in mechanical engineering? Basically a special screw is also a fastening element, which from the first impression should have a head, which as a screw head should be equipped with a possibility for fastening, i.e. with a drive, because otherwise it is not possible to apply a torque, because there is no possibility to apply a tool for rotary movement. This head of a special screw is always directly adjoined by a shank with a thread. This threaded shaft can be completely or only partially threaded. This thread enables each of these screws to create a firm hold in a suitable counterpart. This can be a wood thread, a machine thread, which can be designed as a metric thread or all wood threads. The decisive factor in designating a special screw made of steel or stainless steel is always the shape of the shaft or the design of the head, i.e. the shape of the head or the overall function of the element. The function of special screws made of metal is identical to that of normal, common screw types. The designation has only arisen because special screws only ever have to be used for special fastening types. For example an expansion screw. An expansion screw is also a special screw because it is not a standard. This screw is called this way because it can be pre-tensioned and the shaft can expand and adapt accordingly. The shaft is without a thread, at the point where the expansion effect must begin. We can list thousands of special screws in this chapter, but we would like to give you only a rudimentary indication that the term "special screws" is only a grouped summary to be used as a head summary for all non-normal screws. Let us now turn to the material or the material that such special screws may have. The standard material is always normal steel as solid steel. However, these screws must be coated. If you are looking for special stainless steel screws, you should look for stainless steel screws. This material for special screws can be designed as V2A or V4A and is therefore rust- and acid-resistant.

Special Screws Stainless Steel V2A V4AEven if special screws are still a large niche in mechanical engineering or in the construction of appliances or aircraft, demand has also continued to grow in this area in recent years. This is not surprising for such special screws, as these types of screws are becoming more and more widespread in these areas and the application radii are increasing every year. Now it is the case that especially with special screws, the market has to be served by dealers due to the demand, so that the manufacturing industry can buy such screws in the desired quality and quantities. This presupposes that there are enough dealers who can satisfy this market. Especially in the internet there are not enough online shops available for special screws, which are able to meet the demand. For this reason, we have taken up the extended category of special screws and will include more and more of these screws in our program in the next few years, so that you have the opportunity to buy such fasteners quickly and easily. Exactly this purpose is fulfilled by our online shop, which enables you to choose and buy your special screws in peace, in principle 24 hours a day. In order to offer you the greatest possible security, we converted our online shop to the secure SSL certificate a few years ago and thus a data tap of your sensitive data is no longer possible during the connection and transfer to our merchandise management system. More security is not possible! Let us also give you a few words about the order process, so that you as a customer know exactly how a purchase of your special screws should proceed, so that you can have your purchase delivered quickly. Now we also assume that we may welcome you on our website, because you have found us via a search engine by using the search term "special screws of steel or stainless steel". This is how it should be! Please take your time to look around in the right category and possibly find some of the special screws you are looking for. Have you found the right ones? OK then you only have to enter the desired number of articles and then put the screws into the shopping cart by clicking on them. Done, at least for the first part! Now part two follows, which makes it possible for you to create your account with us. In this account, you can enter your delivery address and also your email contact address for communication between you and us. Now you have the possibility to buy more products or to pay for the special screws and complete the purchase. If you would like to pay for the goods, then follow the shopping cart instructions by clicking Continue until you see our payment options. Select the best one and pay for your special screws. If all was successful, you will receive a payment confirmation and a copy of the order in which you have a list of which special screws you have paid or bought.

The production of special screws

Special Screws Stainless Steel V2A V4ASince more and more of these special screws are being sought and we can offer you, even if only a small part of the special screws, we would like to give you the opportunity in the last paragraph, as always with us, to gain an insight into how such screws can be manufactured. As special screws are mostly larger screws and are not standard, today we use ultra-modern CNC machines for this purpose, which can take over the tasks of manufacturing such precise, highly complex parts safely and in a high quality. CNC screw machines are always used for the production of standard screws, but for these screws large CNC lathes are used, which are by far better suited to create such complex parts. Let us say a few words about the production of such special screws made of metal or steel. These lathes can be used for the individual production of screws, because in this case a production with a loader is usually out of question, because the measuring and control work during the production must always be controlled in order to be able to intervene directly if dimensional accuracy deviates or there are larger differences. In this case, an operator is always standing next to such a machine and has the production process under control. Also with such machines, as with others, a CNC program must be loaded with all data so that the CNC machine or lathe knows exactly what it has to do. All parameters for the production of special screws are stored. These include all feeds, all speeds and tool parameters and much more. In the next step all zero points of the tools have to be set, so that a reference can be created until the production of such special screws can start. Now, when everything is prepared, the blank of the special screw can be clamped and the machine can be started. Now all programmed sequences follow one after the other. As a rule, the shank is always screwed down first to create the basic shape of the special screw. Afterwards, the finishing passes are carried out to ensure that the dimensional accuracy is correct and the thread is screwed in. Once these steps have been completed, the hexagon on the head of the special screw can be milled so that an open-ended spanner can be applied later. In addition, all other specific requests of the customer are taken into account, until finally a clean, smooth and perfectly dimensionally accurate special screw can leave the machine and the house to be sent to you. After a few days after an order you should have the delivery of the ordered special screws in your mailbox.
