Coated Self Drilling Screws

 Definition of Self-drilling screws:

Self-drilling screws are self-tapping screws featuring a drill point used to drill a hole and simultaneously create the mating threads to fasten two pieces of material together. The sharp tip or notch is the unique characteristic that helps identify self-drilling screws that are ideally suited for drilling into wood and metal substructures. The tapered tip acts in the same manner as a drill bit which, along with the natural razor-sharp cutting thread drill, or tap the hole for the fastening process.


In the case of self-drilling screws, the regular need for a pre-drilled pilot hole is no longer necessary as self-drilling screws can tap their own holes and give the design of these screws. Unlike self-tapping screws, which cannot drill through metal objects, self-drilling screws can quickly drill through metal materials and do not need a pilot hole to do so. This feature of self-drilling screws gives it an advantage over self-tapping screws and is more cost-effective, especially in metal projects.

Different variants of self-drilling screws:


The drill point or tip of any self-drilling screw is key to bringing enhanced levels of efficiency for drilling, and tapping projects lead to dual benefits of faster turnaround times at lower costs. The sharp drill point gives the self-drilling screws the ability to fasten at least ½” thick steel to a secondary substructure without much difficulty. Self-drilling screws from global manufacturers like EJOT are available for many construction projects with varying thread lengths, head styles, and drill flute lengths.


The common types of self-drilling screws that are readily available are CSK Head, Pan Head, Wafer Head, Truss Head, Hex Head, among many others. It is crucial to determine the material or materials and their thickness before deciding which self-drilling screw is best suited for the project. Due to not needing a pre-drilled or tapped pilot hole, installing all self-drilling screws requires a simple screw gun instead of a cumbersome drill.


Self-drilling coated screws made by EJOT.


EJOT self-drilling screws join components seamlessly by drilling, forming the thread, and fastening the necessary materials. Purchasing self-drilling screws from EJOT gives engineers and project managers the option of purchasing pre-assembled sealing washers along with the screws.  


Each coated self-drilling screws manufactured by EJOT uses best-of-breed materials, state-of-the-art technology, and strict adherence to compliance standards. Each screw goes through multiples tests for performance, safety, and overall quality.


The coating of these screws performs a protective first layer to prevent these screws from rusting. The premium Anti-Corrosive protective coating protects the self-drilling screws from severe weather conditions like heavy humidity, pollution, acid rains, and UV rays. EJOT has ensured that the heads of its self-drilling screws are given extra protection as only the head of the screws is in direct contact with the environment. The most significant benefit of using self-drilling screws made by EJOT is that stainless steel screws can be opted for in extreme weather conditions or zinc-coated self-drilling screws are the ideal choice for areas not impacted much by changing weather conditions. All these factors are responsible for the making of self-drilling screws from EJOT that are strong, durable, and can withstand the harshest of environments bringing peace of mind to homeowners and project managers alike.

Self-Tapping vs Self-Drilling Screws: The Unknown Differences

Image
  During the construction of a building, people become picky about the iron bars they use. They look for answers to questions like which brand of metal sheets are the best quality, and which company offers the best fixers and plasters in the market, but nobody asks which brand of fasteners is the most reliable. It is ironic how the most critical hardware piece that is responsible for holding the whole structure together is often the most neglected among all the other materials.  The world of fasteners is oblivious to most. Fasteners are of different kinds, from nails to screws to bolts to studs. The list is endless. Within this list, there are two types of screws called self tapping screws and self drilling screws. These two screws are usually mistaken for each other. However, some characteristics make them unique.  What Are Self Tapping Screws? Self tapping screws are also called sheet metal screws due to their heavy use in the sheet metal trade. It contains form mating...

The Differences between Self-Tapping and Self-Drilling Screws

Image
  The difference between self-tapping and self-drilling screws is that topic that has confused many people in the past, and the confusion is still going on with many.  These two stainless steel screws are some of the most widely used fasteners at both commercial and domestic levels. Both of these screws can be used in metal building and other kinds of general construction work as well.  Self tapping screws and self-drilling screws these two terms are never interchangeable. However, you can say that the stainless steel self-drilling screw is a subtype of self-tapping metal screws. So, just let us get a bit deeper into the details of both and understand the merits of each type of these two screws. Self-drilling screw If we talk about the technical terms, both types of screws are self-tapping only because they furrow themselves in their threads. And simply because of the difference in the design of the tip of both the screws, self drilling screws differentiate the work be...

Why an ETICS system needs special fasteners?

Image
  Before we delve into the main question of why there should be specific fasteners designed just for an ETICS system , we should first go over what this system is. External Thermal Insulation Composite System (ETICS) is a multilayer compact insulation solution that may be used to increase the energy efficiency of buildings. The system has a predetermined order in which the layers are added. This arrangement can have anywhere from six to seven to even eight layers which go in the following order of placement: a wall structure (substrate), the adhesive (basic fixing), the thermal insulation, the anchor (and if need be, additional fixing), a reinforcement layer (generally is a base coat embedded with glass fiber mesh), the key coating (if required), the finishing coat (that renders),  any primers (this is also optional), and finally, the decorative coats (again, optional). You can save a lot of money on energy and reorganising by using a professional ETICS system. External therma...
