MS Bolts Supplier

USP Aerospace has a wide variety of quality aerospace fasteners, such as MS bolts and screws for consumer use. Fasteners are items that help to keep machine parts together. Both bolts and screws are commonly used in the area of use. There are many different types of bolts and screws that have varying heads and threads. Essentially, different versions are used depending on exactly how they are going to be used and for what sort of application. That is why it is vital to understand the differences between bolts and screws and how they are used in the aerospace industry.

MS Bolts vs. Screws

When it comes to MS bolts and MS screws, there are some similarities and differences between the two. Read more on the two types of fasteners.


Bolts and screws are basic hardware parts that are required by many machine. These can be simple household items, like dishwashers to complex high-end machines, like airplanes. No matter the application, though, the fastener needs to durable and trustworthy. And with most fasteners, you can be given the option to dismantle and reinstall whatever particular product they are being used for. As a part of their flexible nature, they can also be interchanged among similar items. This means fewer production costs.

A threaded joint is a common feature among both screws and bolts. This bolted joint can hold severe loads and the parts can be separated and reconnected with ease and done so multiple times. These fasteners are available in a few different materials, like stainless steel, copper, brass and alloy steels. Technology has advanced to a state where even porcelain and glasses can be used as screws and bolts. However, those are for more simple uses, like jars or insulators, not in the aerospace field.


Though similar in nature, bolts and screws are empirically different. Bolts are headed fasteners that have external threads, which are suitable for non-tapered nuts. Due to this, they require a nut as a counter-lock to the joint. They are designed to be used as a fastener is placed through an already drilled hole in a machine part. And a nut is required to tighten it at the other end.

Screws are different as they do not require a nut or bolt to ultimately tighten it. They are the simplest example of converting torque into a linear force, as they are shafts with provisions at one end in order to turn the screw. They have a helical thread on its surface that is capable of piecing strongly into whatever surface. Due to the lack of bolt or nut, they are less prevalent in high-end technologies and machines and most common in home-based applications.
