Introduction to Self Tapping Screw

Self-tapping screws is a term generally used for screws designed to cut their own thread in sheet metal, although in a general sense wood and plastic screws are also self-tapping. These types of screws often have a sharp pointed end and sharp threads on a tapered shaft. They may have a section of unthreaded shank, like a bolt.
Self Tapping Screws are uniquely designed to considerably reduce the preparation time of a task by eliminating the need for pre-drilling or washers. They are significantly used in the automotive and construction industry. It also leaves less residue so that you don't have to worry about the mess it often leaves.
Self tapping screws are generally used to secure plastic, metal, wood, plastic, and bricks together. There are mainly two types of self-tapping screws, thread-forming, and thread-cutting. These screws usually follow the same thread each time, thus ensuring a strong, smooth, and consistent bond.

Frequently Asked Questions
 

Q: What is the difference between a self tapping screw and a normal screw?

A: A regular screw has a uniform thread all the way around, whereas a self tapping screw has cutting edges, enabling it to penetrate material.

Q: Can you reuse a self tapping screw in the same hole?

A: Yes, but there is a small chance the screw may come unthreaded when you remove it in the first place.
Make sure to remove the screw carefully with the correct tool for its head type.
If it does come unthreaded, use a slightly larger self tapping screw in its place.

Q: What's the difference between self-tapping and self-drilling screws?

A: While technically both types of screw are self-tapping because they furrow their own threads, the self-drilling screws are unique. Due to the design of the tip of the screw, the point acts as a drill bit meaning you do not have to create a pilot hole beforehand. This design means that the self-drilling screw is cost-effective and time-saving compared to the self-tapping screw in many applications. Errors can also be reduced as you do not have to worry about drilling the wrong size hole for the pilot hole.

Q: What size pilot hole for a self tapping screw?

A: The pilot hole should be no bigger than the diameter of the root of the screw.

Q: Do you need a drill for self-tapping screws?

A: No, self-tapping screws can simply be inserted with either a screwdriver. However, it’s better to drill a small pilot hole before the you drill the screw.

Q: How much weight can a self tapping screw hold?

A: An average screw can hold around 35- 45kg. Although, many factors including the type, weight, length and material of the screw, as well as how it was inserted, the types of forces acting on it and the angle it sits at can affect the amount of weight it will be able to hold.

Q: Do self-tapping screws come loose?

A: Since self-tapping screws may be used multiple times, they can come loose if the hole becomes too big.

Q: Can self-tapping screws be used with wood?

A: Yes, a corrosion-resistant fastener is recommended for use with wood because wood absorbs moisture and this can cause normal screws to rust.

Q: What are the disadvantages of Self Tapping Screw?

A: Self-tapping screws are a type of fastener designed to create their own threaded holes in materials when driven into them. While they offer several advantages, including ease of use and efficiency, they also have some disadvantages:
Weakened Threads: Self-tapping screws can weaken the threads they create in the material. Over time, if the screw is removed and reinserted multiple times, the threads can become less secure and may not hold as well.
Limited Reusability: Due to the weakening of threads, self-tapping screws are typically not as reusable as screws that are driven into pre-threaded holes. Repeated use can lead to a loss of effectiveness.
Risk of Over-Tightening: Self-tapping screws can be prone to over-tightening, which can strip the threads they create or damage the material. This can be a concern when working with softer materials.
Surface Damage: When using self-tapping screws in some materials, they can cause surface damage or deformation, which may not be suitable for applications where aesthetics are important.
Limited Material Compatibility: Self-tapping screws may not be appropriate for all materials. They work well in softer materials like wood, plastic, or thin sheet metal but may not be ideal for hard metals.
Drilling Requirement: Self-tapping screws require a pilot hole or starter hole to begin the threading process. This step can add some time to the installation process, especially when working with hard or thick materials.
Alignment Challenges: Getting the self-tapping screw to align properly with the intended hole can be challenging, particularly in situations where precision is critical.
Lower Holding Strength: Self-tapping screws may not provide as much holding strength as screws used in pre-threaded holes, especially when subjected to shear or lateral forces.

Q: How are self tapping screws measured?

A: Length and diameter are the two most important size measurements for your screw. Here is how self tapping screws are measured:
Diameter is measured from the outer thread on one side of the screw to the outer thread of the screw on the other side. This is called the major diameter. You can also measure the minor diameter, which is the distance from the bottom cavity of the screw on one side to the other
Length is measured differently depending on the head type of the screw.
For screws that are flat on the bottom of the head including pan head, round head, truss head, etc. and hex and washer head types, the length is measured from the bottom of the head to the end point of the screw.
Flat head countersunk screws should be measured from the top of the head to the tip.
Oval head screws are measured from the widest point of the head to the end of the screw body.

Q: Can you use self tapping screws in concrete?

A: Yes, although you will need to obtain self tapping screws specifically designed for use with concrete.
Then, you need to drill a hole in the base material and clean all the dust to ensure it fastens properly.
After you've cleaned the hole, you should slowly drill the screw in place to ensure you do not strip the base material.
It is a good idea to use wall plugs even with self tapping screws as masonry can easily crumble or be stripped whilst you are working on it. Thus, compromising the quality of the installation.

Q: How do self tapping screws work?

A: Self tapping screws have sharp threaded shanks. As you screw them into a material, they carve out their own thread.
A hole often needs to be drilled into the material first. Then, the screw cuts a thread into the sides of the hole as you screw it in.
This is known as a pilot hole, and it should be the same diameter as the root of the screw.
Some thread tapping screws have pointed tips, meaning they don’t always need a pilot hole.
Self tapping screws can be installed using handheld and electric screwdrivers, wrenches, Torx keys, Allen keys or security tools depending on the head type of the screw.

Q: Are there any similarities between Self Tapping Screw and Self Drilling Screw?

A: Both have the ability to tap their own threads.
Both are ideal for metal building construction
Both can fasten metal, aluminum, and plastic components

Q: Will self tapping screws go through stainless steel?

A: Self tapping screws will not go through stainless steel, but they will work if a pilot hole is drilled first. Self-drilling screws will go through stainless steel and tap a thread as well.

Q: What are the characteristics of Hex Head Tapping Screw with Flat Washer?

A: Here are some features of hex head tapping screw with flat washer:
Tapering threads: The threads taper down to the point, allowing the screw to form threads into the material as it is installed.
One piece: The washer and hex are formed together as one piece.
Weather-tight seal: An integral EPDM washer installed into the head provides a consistent weather-tight seal.
Heat treatment: Heat treatment increases the strength and holding abilities of the screws.

Q: What are the types of Self Tapping Screw?

A: There are two types of self-tapping screws - thread-forming and thread-cutting.
Thread-Forming: Before you can use these screws you will need to drill a pilot hole as the screw itself does not contain a pointed tip. Thread-forming screws join plastic materials together. Due to their design, they grip materials more tightly. Care should be taken as there is a risk of over-tightening the screw, which can result in the joined materials breaking from the pressure
Thread-Tapping: These screws do not require a pilot hole but one can be drilled to make fastening easier. Remember to make the pilot hole smaller than the thread-tapping screw diameter. Thread-tapping screws remove material and create a path for the screw. The drawback to using this type of screw is that when they are removed it can result in stripped threads. If you experience stripped threads, you should use a larger thread-tapping screw when reattachment is made
