There are countless different types of screws, bolts, and other fasteners and fixings. Machine screws are one of the more widely used products among dozens of standard fastener types.
Despite their widespread use, there is no strict definition of a machine screw. The term ‘machine screws’ covers a broad range of fastener varieties.
Machine screws can be either coarse-threaded or fine-threaded, and are usually available with a wide range of head types. So, what is a machine screw, and how can you easily define one? Moreover, how exactly are machine screws different from other types of bolts or fixings?
The simple answer is that machine screws are usually distinguished from other common fastener types like wood screws by their physical features and intended uses. Some of their typical physical characteristics are outlined below:
Standard machine screws tend to be somewhat smaller (both in length and diameter) than many other types of bolts and fasteners
Machine screws are almost always blunt-ended (flat-tipped), unlike many other screw types which taper to a sharp point at the tip
Although this isn’t always the case, most machine screws are fully threaded, meaning that the threading runs the full length of the fastener shank from just below the head right to the end
Machine screws are usually stronger than many other screw types. They are manufactured to high standards using refined techniques, providing better all-round quality, precision, and thread uniformity
Machine screws are typically designed with finer, more accurate threads than alternative fastener types. They are generally intended for use with a pre-drilled interior tapped hole or a nut
Machine screws are most often used for fastening metal parts securely together in various types of machinery or construction. Other uses include vehicles, engines, tool assembly, electronic devices, and large-scale industrial equipment

Self-tapping screws are a type of fastener with a unique feature. They are able to tap their own threads in materials like plastic, wood and metal. Self-tapping screws are split into two main categories, Thread-Forming and Thread-Cutting. The screws are similar in the job they do, however, they have two differences. One of the screws has a flat base, the other has a sharp point.
The difference between self-tapping and self-drilling fasteners is that self-tapping screws will tap a hole into a soft material, self-drilling screws are capable of drilling a hole into anything from metal to wood meaning no pilot hole is needed.Thread-Forming Screw
Before using this self-tapping screw, it is recommended that a pilot hole is drilled into the material. As thread-forming screws have a flat nose, it makes the drilling process easier and are used when fastening plastic together.Thread-Cutting Screw
This self-tapping screw does not require any preparation. As it has a pointed tip, it is not necessary to create a pre-drilled pilot hole. Thread-cutting screws are able to pierce a small entry hole while being driven into the material the thread is being created.
Self-tapping screws are used where an application requires regular maintenance and regular easy access. These screws are useful in situations where products have to be assembled and disassembled, such as access panels or even furniture.
