How Are Screws Made?
There are two different manufacturing processes for making screws. Most screws are made with the thread rolling method. Machining is used to make small or specialized screws that cannot be made by thread rolling.
The first step in making a screw with the thread rolling method is called “cold heading.” A wire is fed into a machine to straighten it, then cut it to length. The machine then cuts the head into the desired shape.
There are three techniques that can be used to cut the blank screw to give it threading:
- Reciprocating die: There are two flat dies — one is stationary, and the other moves back and forth. The screw is rolled between the two dies.
- Centerless cylindrical die: The screw is rolled between two or three round dies to create the thread.
- Planetary rotary die: As the screw is held stationary, several die-cutting machines spin it around.
Between these two screw manufacturing processes, thread rolling is better. The screws are more durable and high quality, avoiding weaknesses in the metal. The screw threads are placed precisely as well, so all screws are the same.
What material are screws made of
Screws are vital to the success of many different projects, whether you’re a do-it-yourself enthusiast or a service industry professional. However, you should consider some critical areas before you invest in screws for your next job. In this guide, we will answer all of your questions about screws:
- Does it matter how screws are made?
- What are screws made of?
- What does the coating on screws do?
- How do I decide what screw to use?

What Are Screws Made Of?
Screws can be made from all sorts of materials, yet there are some that are more popular than the others. The four most common screw materials are:
- Steel: This is by far the most common material used for manufacturing screws, and there’s a simple explanation for why — steel is less expensive than some other screw material options.
- Copper: Copper screws are good for fighting against corrosion. If a screw is going to be exposed to the elements, copper helps to ensure the screw performs durably over the long-term.
- Aluminum: Aluminum isn’t as durable as other materials, but it does have one thing going for it — its weight. Aluminum is just about the lightest weight fastener you can find.
- Titanium: When you need a blend of strength and lightness, go with titanium. You’ll often pay a premium for titanium screws, but that extra cost pays off big time when you need a fastener that is robust but doesn’t weigh much.
Which Screw Should I Use?
No two kinds of screws are alike. Before you buy screws for your next project, consider these points to make sure you are getting the right kind.
First, identify what materials you are screwing into. Different kinds of screws are made to fasten different materials. For example, the strongest wood screws are made for joining two pieces of wood. Once you’ve determined the material, measure its thickness. You’ll want to get a screw that is long enough to pass through the material and at least halfway into the next for a secure grip.
The next consideration is material. This decision will be based on where you plan to use the screw — indoors or outdoors. For an indoor project, you may be able to use a less expensive screw that looks pleasing if it will be visible. Outdoor projects need certain kinds of screws since they will be exposed to temperature changes and moisture. Then, consider the coating options to gain even more ideal qualities.
What About Coatings?
Screws are often coated to make them even better by giving them desirable qualities. Screw coatings open up a vast number of possibilities when you’re seeking the right fastener for a specific situation. For example, screws can be coated in copper, ceramic, zinc and other materials, which can provide extra strength, extra protection against corrosion or even an aesthetic quality that might otherwise be missing.
For example, a zinc-plated steel screw will better fight corrosion than a steel screw on its own. Likewise, a copper-plated screw may look more attractive in a prominent place than a steel screw would.

A relevant point worth mentioning
What material is used to make screws?
Screws and bolts are usually made of steel. Where great resistance to weather or corrosion is required, like in very small screws or medical implants, materials such as stainless steel, brass, titanium, bronze, silicon bronze or monel may be used.
