Set screw as the name suggests are used to set objects against or within each other. These screws are also sometimes headless and as a result have to be driven using an internal drive for wrenching such as hex or square sockets and slots. We see the set screw being used for securing of gears to a shaft. By using them the relative movement present between two different objects can be totally prevented. As a result each is able to function exactly the way you wish them to function. Stainless steel and brass is generally used during the manufacture of these products. It gives it resilience and durability.
The set screw is designed in such a way that they pass through the outer object and remain against the inner one, securing them both in place. The main difference between these screws and the traditional ones is that in most of the cases an internal mechanism needs to be used up when securing them up. Not only the head region but also the pointed ends of the set screw are of various types based on their applications. There are also some screws which have been specifically developed for flexi uses.
Uses of set screw
The commonest use where we find the set screw is in levers, locks and doorknobs. For the installation of the doorknobs first of all they are placed against the surface on the exact spot where they are to be set. Once this is done the next step is the placement of the ‘rose’ plate. Finally the appropriate set screw gets driven inside the plate to secure the knob in the right place and prevent the plate from moving around and interfere during the opening and the closing of the door. Besides this most common use we also find these screws being used in a lot of mechanical as well as industrial applications. Mostly these are seen where rotating items such as the wheels are required.
Various types of set screw
We find a wide variety of set screw in the market these days. The commonest one is the cup point. As the name suggests there is an indentation which is shaped as a cup at one of the ends. These are basically used where a temporary assembly is required. Because of their high resistance and fantastic grip they are quite a favorite among the users. Another type of such screws includes the flat points. These ones are required when compressions need to be created as well as in situations which require temporary assembly. The oval pointed ones are also for parts which need a frequent repositioning.
The cone pointed screws give the strongest binding between objects. This is because the pointed ends of these products have deep penetration capabilities and as a result they hold the various parts with a robust strength. When you require a permanent setting of parts, the cone shaped tips are the best choice in every manner. Pointed half-dog set screw are another type which can be used in places where permanent setting is needed between two rotating parts.
