Everyone who builds, contracts, or even builds things as a hobby knows that tiny parts of a structure carry the biggest load. Screws and fasteners may look simple, but they determine whether a roof stays leak-free, whether a joint fails under load, and whether something lasts for years or needs to be fixed in a couple of months.
One of the most commonly asked questions is: “Should I use self-drilling screws or just screws?” Well, we know the answer mainly depends on your project, your budget, and your expectations. In this blog, we’ll talk about which one we should use, compare their usages, and explain why Tata Agrico Screws, manufactured by Tata Steel, are the trusted choice for both.
What Are Regular Screws?
Definition and Common Uses
Regular screws are considered the oldest type of fasteners available. They were made specifically to hold together materials like wood, sheet metal, or light structures. When using regular screws, it is often necessary to drill a pilot hole first, and then fasten the screw with a screwdriver or drill.
They are popular for:
- Furniture assembly.
- Wood frames.
- Light-duty applications.
- Regular household projects.
Implications of Regular Screws
A regular screw is somewhat versatile, but it’s not without some trade-offs:
Pre-drilling: This creates an extra step in the process and adds labor time.
Loose: Regular screws may not have the same holding power in a heavy vibration environment.
Time Delay: Because they take longer to install, regular screws aren’t the best fit for big roofing or industrial jobs.
What Are Self-Drilling Screws?
Key Features
Self-drilling screws are advanced fasteners designed with a built-in drill tip for easy installation. In other words, there is no need for a separate pilot hole, as the screw will cut directly into metal or sheet as you drive it in.
Notable features in self-drilling screws include:
- Faster to install
- Superior grip when combined with full thread screws
- Commonly used in roofing and large commercial metal construction
Benefits of Self-Drilling Screws
Time-saving: No need for pilot holes, as you can drive straight into materials without the delay of pre-drilling. Labor costs will reduce.
Durable: We stock corrosion-resistant screws as well, great for outside work.
Leak-proof roofing: When used with washers, they are specially designed so that your roofing is completely leak-proof.
Trusted brand alternatives: If you’re looking for a reliable option, Tata Agrico Screws also provides self-drilling types designed to withstand the challenges of Indian climates.

When Should You Choose Self-Drilling Screws?
Self-tapping screws are perfect for:
- Roof and gutter projects → Quickly install color-coated sheets, JSW, or SAIL roofs.
- Industrial sheds and warehouses → Easily transit through the details and install in record time.
- Connecting metal to metal → Provides for a much stronger clamping force.
- Coastal or humid environments → Rusting is not an issue with Tata Agrico’s screws, which are all corrosion-resistant.
When Should You Choose Regular Screws?
Regular screws are okay for:
- DIY jobs at home → furniture, shelving, or picture frames.
- Woodwork → securing planks, panels, and wood joints.
- Small-scale projects → speed isn’t really a factor.
For basic fastening jobs, they’re a straightforward, budget-friendly, and trustworthy choice.
