Socket Set Screws: Sizes - Dimensions & Specifications

In a nutshell, a set screw is defined as a type of screw that is designed to secure one object within another one. An example of this is when you need to secure a gear to a pulley. In such cases, regular fasteners such as aluminum hex head cap screws may not be ideal, since the jutting head could end up compromising the function of the gear and pulley assembly. Feb 05,  · A set screw is a unit of hardware designed to fasten one object inside of another. The set screw prevents relative movement between the two objects, which allows each to function as intended. These screws are generally made from brass or stainless steel, and are designed to pass through the outer object and rest against the inner object without passing through.

When you are interested in using fasteners, you may come across some that you may not be very familiar with. Most of the time, these turn out to be highly specialized what is a set screw that are designed to perform a what is a set screw function, and which are usually sold by a limited number of high quality vendors.

However, just because they are not very commonly used does not mean that you should not know anything about them. If you are in an industry where you use a large number of fasteners, it would be a good idea to know something about some of these rare fasteners, since you may find out that you actually need them to improve the quality of your products.

One of such fasteners is the set screw. In a nutshell, a set screw is defined as a type of screw that is designed to secure one object within another one. An example of this is when you need to secure a what is a set screw to a pulley.

In such cases, regular fasteners such as aluminum hex head cap screws may not be ideal, since the jutting head what is a set screw end up compromising the function of the gear and pulley assembly. However, due to the design of the set screw, it can be embedded within both the pulley and the gear without having any protruding parts. The most obvious feature about set screws is the fact that they are usually headless.

Such fasteners, also known as blind fasteners, are usually fully threaded throughout the whole body. On account of this, they are usually put in place using a machine known as an internal wrenching drive, or an Allen key.

In addition to that, Robertson sockets and slots can also be used to put them in place. Once in place, this fastener exerts a clamping force that will hold the two items it is connected to together.

Set screws can be made in any material that a regular fastener can be made in, such as aluminum, titanium and steel. You may therefore need to figure out which type of metal will be most ideal for a particular application, so that you can get a set screw made out of that material. Most commonly, set screws are made out of alloy steel.

Alloy steel socket set screws are usually tougher than other types of fasteners, and thus last longer. Set screws are all designed to have a specific point type, which is the type of tip the fastener has. Which tip you select will depend on the engineering qualities you hope to achieve. For instance, if you want a screw that will press on a flat surface, you could get one that has a flat point. You can also get screws with cup points if you want the how to help a nervous stomach tip to have a reduced surface area of contact without experiencing huge stresses.

Other point how to fix my american girl dolls frizzy hair include the domed points, cone point, knurled cup point and extended points.

What is a Set Screw? Set screws are used when one component has to be fixed within another one without any protrusions which could decrease the efficiency of the equipment. For example, fastening a gear and shaft assembly with a regular hex bolt might be inefficient as the hex head might cause inconveniences for the smooth operation of the assembly. Oct 29,  · A Set Screw is a headless screw (appropriate for our Halloween edition) fully threaded from end to end. Traditionally classified within the Socket family of products, Set Screws are comprised of 3 main parts: the drive, the thread and the point. They (generally) have a hexagonal drive on one end, and a point on the other. Setscrews are semipermanent fasteners that hold collars, pulleys, or gears on shafts. They are categorized by drive type and point style. An important consideration in setscrew size selection is.

What can set you apart as a quality manufacturer is your knowledge of specialised equipment used for unique purposes. One such specialised fastener is the socket set screw - it is not widely available with most fastener suppliers.

Getting to understand rare fasteners can help you simplify processes which would otherwise require complex solutions to perform the same action. Set screws are used when one component has to be fixed within another one without any protrusions which could decrease the efficiency of the equipment. For example, fastening a gear and shaft assembly with a regular hex bolt might be inefficient as the hex head might cause inconveniences for the smooth operation of the assembly.

In such situations, where protrusions are not desired, a set screw can effectively fasten the components together without interfering with the operations. A set screw can be identified with its signature headless body. The entire body of the fastener is threaded and it comes in various dimensions.

To securely fasten the set screw in place, a special internal wrenching drive or an Allen key is used. Once the components are fastened, the set screw exerts a clamping force in order to secure the components in place. Set screws have different point types based on the characteristics required out of them. A few examples of its point types are, plain cup, knurled cup, flat, oval, cone, half dog, and soft tipped.

A straight-slotted set screw, as the name suggests, can be used with a flat screw driver to be inserted and removed. Very little torque is required to keep this in place but it mostly finds its use in very simple applications. The head of the set screw comes with a hex recess and requires a special hex wrench or Allen key to be used on it.

It is often tamper-resistance and can be used with more complex requirements. A square socket set screw, also known as Robertson or scrulox screw drive, comes with a square protrusion on the tool. The tool as well as the socket come with tapers which makes the installation of the fastener very easy.

With the external hex screw drive, a six sided tool or a special wrench with a combination or adjustable point sockets has to be used. This head type is preferred over the square socket in places which has restrictive space surrounding the set screw.

This requires a four sided adjustable wrench or an open ended wrench to be used on it for any operation. This set screw comes with four or six splines at the head. However, this does not make the fasteners tamper-resistant. The grooves are cut using a square-cornered broach, giving the outer corners of the drivers a slight undercut. Once the torque is applied in the right direction, the possibility of splitting the fastener is completely eliminated.
