This article introduces the reader to Slotted and Torx pan head machine screws. You will also learn about Sheet metal screws, Thread forming screws, and wood screws. Then you will be able to make informed choices when using machine screws in your project. And remember, these types of screws are available in a variety of sizes, and their application is not limited to a single material. They can be used for a wide range of purposes, including automotive parts and home improvement projects.

Slotted and Torx screws have different thread sizes, and you'll need to decide which one you need.
Pan head machine screws have a distinctive appearance. Their wide heads and high, flat surfaces provide a large mating surface, minimizing the chances of cam-out or crushing. In decorative applications, these screws have a flat or slightly domed profile. The socket on these screws is typically a slot, and they're usually used for small jobs. But, if you're using large screws, you can use Torx pan head screws instead.
Sheet metal screws
There are several different types of sheet metal machine screws, and each has its own special features and advantages. Type A screws, for example, don't require the need for pilot holes and can be used in a variety of materials.

Thread forming screws
Machine screws and other fasteners often have thread-forming screws installed as part of the assembly process. These screws are used to effectively join dissimilar materials. Thread-forming screws eliminate the need for spot welding and provide excellent joint performance for lightweight materials. To learn how thread-forming screws can benefit your assembly process, read this article. It's packed with tips on choosing the right fastener. You'll be glad you did!
A thread forming screw forms a coarse thread without producing chips. Three vertexes perform a roll-forming process to produce mating threads. This eliminates the need for tapping unthreaded holes. The advantages of this type of screw are many, including improved thread quality and higher strength than Type C or CA. Here's a closer look at two types of thread forming screws: the coarse Type B thread and the smoother Type C thread.
Wood screws
If you're not sure whether to use wood screws or machine screw, there's no need to fret. The difference between the two is only the head shape. Wood screws have a pointed tip, and machine screws are flat and don't require a pointed head or wide thread. Despite their name, machine screws aren't ideal for wood, because wood is softer than metal. If you're unsure, read the following tips to make sure you use the right screw for your project.
Before screwing anything into wood, be sure to pre-drill the wood first. Machine screws have a thread that is slightly smaller than wood, and it's designed to fit properly into the screw hole. Because metal is stronger than wood, the force it takes to strip the thread is much greater than the strength of the wood. This prevents the screw from pulling out of the wood and causing cracks. To reduce the risk of cracking, pre-drill the wood.
