Types of Tapping Screw
 

The tapping screws produced by our company mainly include the following types:

Self Tapping Screws for Plastic

Plastics can be very rigid and therefore susceptible to splitting and cracking making it important to drill a pilot hole of the required diameter in the plastic substrate for the self tapping screw. While standard self tapping screws are suitable for most plastics there are specially designed self-tapping screws for plastics which have more pronounced, sharper threads that create a more robust fastening that is less susceptible to being pulled out and thread-stripping.

Self Tapping Screws for Wood

Using self-tapping screws for fastening to softer woods doesn’t require the drilling of pilot holes. But when using self-tapping screws with harder woods drilling pilot holes, smaller in diameter than the screw shaft, is always recommended. Its important to consider the screw material as moisture in the wood can cause corrosion. So stainless steel or corrosion resistant self tapping screws are recommended.

Self Tapping Screws for Metal

When using self tapping screws in metal pre-drilled pilot holes are always needed. The hardness of the metal substrate must be considered when using self tapping screws as the self-tapping screw might be softer than the metal material into which it is being screwed. This would damage the self tapping screw and result in an insecure fixing.

 

 

 
 
Applications of Tapping Screw
Tapping Screws For Wood

Sheet Metal works

Tapping screws are used for fastening metals together when framing different objects such as automobiles, machineries, furniture etc. They are ideal for almost any type of metal working because they possess a pointed drilling tip.

Medical applications

Many medical articles had made mention of the use of tapping screws in human surgery. They are used as fasteners when surgeons carry out the replacement or repair of certain tissues in the body.

Municipal works

When it comes to construction of gutters in towns and cities, Tapping screws are most preferable in making the gutter-attachment system. These screws offers a rigid hold on gutters, thus helping to keep the gutter intact even under adverse atmospheric conditions.

Roofing solutions

This is infact one of the most common applications of tapping screws. They are used for framing materials together to form roofs. It doesn't matter what kind of material it is, Tapping screws can be used to provide an intact hold on wood, metal or asphalt roofing.

 

Step to Use Tapping Screws
 

Step 1: Choose the Right Screw for the Job
Before you begin, it is critical to choose the correct self-tapping screw for your application. Consider material compatibility, screw size and length, and the level of strength and holding power required. Consult manufacturer recommendations or hardware shop specialists to verify you have the correct screw for your job.

 

Step 2: Prepare the Materials
Check that the items you’re using are clean and clear of debris. Pre-drill pilot holes in the material if necessary, using a drill bit that matches the diameter of the screw’s core. Pilot holes guide the self-tapping screw into the material, preventing it from breaking or damaging it.

 

Step 3: Positioning and Alignment
Insert the self-tapping screw into the material at the specified spot. Check that the screw is aligned with the desired path and angle of insertion. For improved handling and control, use a screwdriver or power drill equipped with a matching screwdriver bit.

 

Step 4: Start Slowly and Apply Steady Pressure
As you drive the self-tapping screw into the material, start slowly and apply steady pressure. Excessive force may result in stripping or damage to the screw or material. Take care not to overtighten, especially when working with softer materials.

 

Step 5: Monitor Depth and Screw Tightness
Keep an eye on the self-tapping screw’s depth as it enters the material. Take care not to overdo or plunge the screw too deeply, as this will weaken its hold. When the screw is flush with or slightly below the material surface, stop spinning it.

 

Step 6: Repeat the Process
If you need to use numerous self-tapping screws, follow the previous steps for each screw. Maintain consistent alignment, pressure, and depth throughout the installation to guarantee uniformity and stability.

 

Step 7: Finishing Touches
Inspect the self-tapping screws that have been installed to ensure that they are secure and flush with the material surface. Make any necessary adjustments or tighten any loose screws if necessary. If the screws are visible and appearance is important, consider using screw caps or covers to conceal the screw heads for a more polished appearance.

FAQ

 

Q: What does a tapping screw do?

A: Self tapping screws are mostly used when the medium into which it will be screws is something like metal. Although, self tapping screws are also used to drill wooden and plastic materials. They tend to have a sharp point, and the threads are also sharp to act like knives cutting into any kind of medium.

Q: Do you need to predrill holes for self-tapping screws?

A: Self-tapping screws are designed to tap their own hole in the desired material, meaning that no pilot holes needs to be drilled before hand.

Q: Do tapping screws require threaded holes?

A: While a self-tapping screw can cut its own threads it does require a pilot hole. Similar to using a thread tap, an appropriately sized hole needs to be cut into the base material for the screw to start cutting threads.

Q: Can you use self-tapping screws twice?

A: No. Since the material's substrate can become damaged when removing the screw, so it is necessary to use a new screw. The replacement self-tapping screw should have a larger diameter to rethread the hole and ensure a secure fixing.

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

A: Self-drilling screws drill their own pilot hole and tap their own threads, while self-tapping screws create their own threads but require a pilot hole to be pre-drilled. In essence, self-drilling screws eliminate the need for a separate drilling step, making them faster and easier to install in some situations.

Q: How many pounds can a self-tapping screw hold?

A: These screws can typically hold around 80 to 100 pounds of weight, but the holding power depends on the length of the screw and the insertion angle. Self-tapping metal screws can become stronger with certain alloy compositions, depending on the amount of chromium or nickel.
