Red Hex Head Self Drilling Screw With EPDM Washer

Short Description:

Self – drilling screws for color steel tiles, boasting an extensive range of specifications with lengths varying from 16mm to 100mm and diameters including M4, M5, M6, etc., along with diverse head styles like hexagonal, cross – recessed, and pan – head, some integrated with waterproof washers. These screws are meticulously crafted from top – tier materials: galvanized carbon steel offers excellent corrosion resistance for general outdoor applications, while stainless steel variants ensure superior durability and rust prevention in harsh, coastal, or high – humidity environments.

These versatile screws are not only perfect for the installation and reinforcement of color steel tile roofs and walls in residential, commercial, and industrial buildings but also play a crucial role in the construction of agricultural sheds, warehouses, and prefabricated structures. They are highly suitable for joining light – gauge steel keels, fastening metal sandwich panels, and securing metal guttering systems. Moreover, they find extensive use in the repair and maintenance of existing metal structures, ensuring a secure and long – lasting connection. With a simple power drill, these self – drilling screws can be effortlessly installed, providing a robust and reliable hold that withstands the test of time and diverse weather conditions.

Introduction

These are self – drilling screws for color steel tiles. They belong to the category of self – tapping screws. Usually, their heads come in different shapes such as hexagonal and cross – recessed. The tail of the screw rod is sharp with threads, and some have a sealing washer under the head, which can enhance the waterproof performance. They are mostly made of carbon steel with galvanized treatment or stainless steel, providing good rust – prevention and corrosion – resistance capabilities.

Application Scenarios

They are mainly used for the installation and fixation of color steel tile roofs and walls. They can directly drill into and screw into metal sheets like color steel plates. Additionally, they are also applicable to the connection of light – gauge steel keels and other related building structures.

Usage Method

First, determine the installation position on the color steel tile or relevant metal material. Then, use a suitable power tool (such as a cordless drill) equipped with a bit that matches the screw head type. Align the screw with the pre – determined position, start the power tool, and slowly drive the screw into the material. The self – drilling tip will penetrate the material while the threads gradually embed, achieving a firm fixation.
