How Do the Different Types of Screws You Sell Vary in Use?

We carry a wide variety of screws and fasteners designed for a range of purposes. Our self-piercing screws feature a twin-lead thread and sharp tip to easily puncture sheet metal, digging deep into the material. These are also used in residential HVAC duct work. If you have a wood-to-metal application, reamer screws are your best option.  Self-drilling screws, which are also known as Tek® screws, are ideal for work on commercial HVAC equipment or duct installation.

ZIP screws, also called needlepoint screws, are perfect for 28- and 30-gauge metals. This tool is highly versatile due to its self-piercing and self-tapping abilities. Our specialty screws come with a range of uses, including exterior work, masonry and security.

How Do I Measure Screw Size?

To determine the diameter of a screw, measure the distance from the outer thread on one side to the other. This calculation is called the major diameter. Do not include the head in your measurement.

The inclined plane degree of the screw’s threading indicates the pitch of a screw. The thread pitch represents the number of threads per inch. The distance from the tip to the flat part of the head determines the length.

Always measure from underneath the head of the screw to the tip of the point. On flat head and countersinking screws, measure from the top to the tip of the screw.

How Do I Determine What Type of Screw I Need?

Consider several factors before buying a screw or fastener, including:


-Is the head design suitable for your equipment?

-What type of material will you be joining together?

-Is your application indoors or outdoors?

-What screw length is best for your job?


Give us a call if you have any specific questions about screw selection and we’ll help you find the right tools for your project.

What Are the Different Types of Screw Heads?

Screw heads are typically flat or round. Flat heads allow you to countersink the screw into the material. Rounded heads are standard for machining and eliminate the need for washers. Other common head styles include hex, bugle, oval, pan and truss heads.

You can also choose what type of drive your screw uses, including popular choices like:



– Square.



What Are the Different Types of Screw Threads?

The uses of fine and coarse-threaded screws depend on the application. Finer threading provides a higher stress area and allows for better adjustment accuracy than coarse threading. If you need greater strength, a finer thread is always the better choice.

Different styles of screw threading include:


-Standard thread.

-Square thread.

-ACME thread.

-Buttress thread.

What Are the Different Kinds of Screw Points?

Screw points range from blunt edges to sharp points to penetrate materials. The three industry-recognized point or tip styles are:


-Tapping screw points.

-Thread cutting screw points.

-Thread forming screw points.


Self-drilling screws work with metals and soft steel. Our self-drilling screws have a number from 1 to 5 — the higher the number, the thicker the material the screw can penetrate before it needs a pilot hole.
