Product Description

What is A Self Drilling Screw?
Self-drilling screws, also known as Tek screws, are a type of fastening device that can tap and thread a material simultaneously. They have a unique drill-like flute at their tip which allows them to drill into materials without the need for pre-drilling a hole.

Product Parameters

Benefits Of Self Drilling Screws
Self-drilling screws do not need any kind of pre-drilling or pre-fixing. Self-drilling provides efficient performance by reducing preparation time and constantly ensures a precise and durable bond. Self-drilling screws have been designed to penetrate or cut directly into the material. This allows the users to cut out the pre-drilling step in the process and create an unbeatable tight thread.Your time, resources and stress will be simplified using the self-drilling screws.

Installation Instructions

Step 1: Select the Proper Screw
Choose a self-drilling screw that is appropriate for the material thickness and type you are working with. The length of the screw should be sufficient to penetrate and secure the materials being fastened together.
Step 2: Mark the Fastening Points
If precise positioning is necessary, mark the points on the material where the screws will be installed. Use a pencil or marker for visibility.
Step 3: Install the Screw
Place the tip of the self-drilling screw on your marked point. Using a power drill or impact driver with the appropriate bit size for your screw's head (usually a Phillips or hex head), press firmly on the screw. Start the drill at a low speed to establish the screw position, then increase the speed to drill the screw into the material. Keep the drill bit aligned straight to ensure the screw penetrates properly and to avoid stripping the head.
Step 4: Check for Correct Installation
Once the screw is fully driven in, check the fastened materials to ensure they are tightly secured without any gaps. The screw should not be overtightened as this can strip the threading or damage the material.
Step 5: Repeat as Necessary
Follow the same steps to install additional self-drilling screws at the required intervals to complete your project.
