Avoiding Common Mistakes When Using Self-Drilling Screws

The various types of self-drilling crews can sometimes confuse us about their wide usage. Improper use of these fasteners will eventually lead to damage, failure, expensive repairs, and safety risks. To avoid such incidents, individuals should be aware of basic information and the common mistakes they have to avoid when using self-drilling screws. When one understands the process of using different kinds of fasteners, the job will be more likely to be effective and successful.

In this blog post, we’ll explore some common mistakes people make when self-drilling screws in Ludhiana, Delhi, Noida, Raipur, Ahmedabad, Srinagar, and nearby areas.

Common Mistakes in Self-drilling Screws Selection and Installation


1.Choosing the Wrong Material and Grade

According to the leading self-drilling screw installation experts in Dehradun, choosing the correct material and grade is the first thing you should consider when buying screws. There are various materials out there, each with its own unique qualities that may make it suitable or unsuitable for a particular use, which isn’t enough.

However, we need to go a step further because each material is made up of different chemicals. These distinct compositions are called material grades. Each grade also possesses its own characteristics, making it better suited for some environments than others.

For example,
Stainless Steel: Corrosion Resistant
Grade 316 Stainless Steel: Corrosion Resistant Even In Extreme Saltwater Environments

2.The use of the wrong tools

Using the wrong kind or brand of self-drilling screws can negatively impact the installation of every fastener. Leading self-drilling screw installation and application technicians in Ludhiana reveal that fasteners have specific drives on their heads, which allows you to pick the perfect drive tool to use. Using the wrong tool usually leads to untightened parts or loose assembly.
Moreover, using impact tools on screws can weaken their structure, make them harder to tighten, and lead to uneven weight distribution. This can cause screws to become damaged and fail altogether.

3.Using Reactive Materials Together

It’s not common knowledge that metals combined can actually weaken their integrity. For instance, aluminum and stainless steel. When they’re together, an electrolyte (such as salt water) is introduced, and electrons transfer, creating an unstable balance. This weakens the materials and makes them more likely to corrode. To extend the lifespan of fasteners, it’s important to avoid galvanic corrosion.

4.Not Using Appropriate Locking Fasteners

Locking fasteners are an excellent addition to screw assortments assembly, but can be some situations where it’s absolutely necessary to use them. Leading self-drilling screw applications and installation experts in Raipur reveal that if you’re putting together something that gets a lot of shaking or vibrations, it’s a good idea to use some kind of locking fastener to keep everything in place.

5.Mixing Threading or Imperial and Metric

Not all fasteners are created equal. Another common mistake people commit is trying to fasten the wrong types of fasteners together. Top self-drilling screw installation and application contractors in Ludhiana reveal that every type of fastener should easily thread by hand.

There are various tools you can use to check the threading and size of fasteners easily. Make sure to check the required size before attempting to force the connection.

6.Wrong-Sized Drivers

A driver is designed to fully fit the fastener’s driver recess. Always ensure you’re using the correct driver, as a loose driver will drastically increase the risk of stripping and cam out. Furthermore, make sure you’re using the correct drive for sockets and wrenches.

Top self-drilling screw installation specialists in India reveal that many people attempt to use an imperial hex head or a metric socket because it is a close match. At Screw Expert, we strictly advise against doing this. The recess isn’t a close enough match and will put most of the force on the points of the hex head. Applying too much force can cause the points of the hex head to bend or deform, leading to a stripped hex head.


Self-drilling screw application and installation workers in Delhi, Srinagar, Noida, Raipur, and surrounding areas are often reminded not to overtighten or overdrive fasteners, as they can cause some major issues. Let’s explore this with the help of an example of overtightened joints with a washer. The excessive pressure and stress placed on the washer can impact its effectiveness and performance. If the washer is meant to seal, it may struggle to withstand the extra stress, leading to accelerated corrosion compared to normal conditions.

Making the Right Choice

Don’t overlook fasteners in your design—it’s a common mistake that can cause problems later on. If you use low-quality self-drilling screws or assume that all fixtures are the same, damage or failure is more than likely. The right hardware ensures your non-permanent joints remain stable and intact. Ultimately, it’s about the integrity of your finished good and your company’s reputation.
