Self Drilling Screws

Self-Drilling Screws and Australian AS3566 Standard

Self-drilling screws, often referred to as Tek screws, are specialized fasteners designed to create their own hole while being driven into various materials. They feature a sharp, drill-like tip that allows them to penetrate and cut through metal, wood, or plastic without the need for pre-drilling. Self-drilling screws are widely used in construction, manufacturing, and other applications due to their efficiency and ease of installation.

Key Features of Self-Drilling Screws:

1. Drill Point:
   The defining characteristic of self-drilling screws is their unique drill point that eliminates the need for pre-drilling holes, significantly reducing installation time and effort.
2. Thread Design:
   These screws typically have a deep, coarse thread that provides superior holding power and allows for easy driving into the material.
3. Material and Coating:
   Self-drilling screws are often made from high-quality steel or stainless steel and may be coated with corrosion-resistant finishes, such as galvanization or black oxide, to enhance durability and longevity in various environments.
4. Versatility:
   They can be used for a variety of applications, including metal roofing, wall systems, and various construction projects.

Compliance with Australian AS3566 Standard:

The Australian AS3566 Standard is a specification for self-drilling screws that ensures their quality, performance, and suitability for Australian conditions. This standard covers several key aspects:

1. Material Quality:

Self-drilling screws are typically made from carbon steel, stainless steel, or alloy steel because this choice of material affects the screw’s strength and corrosion resistance. BoldTech self-drilling screws manufactured under the AS3566 standard are made from high-quality materials that meet specific mechanical properties to ensure adequate strength and performance. Additionally, stainless steel screws offer excellent corrosion resistance, making them suitable for outdoor or humid environments.

2. Corrosion Resistance:

The standard dictates requirements for corrosion resistance to ensure that screws can withstand the harsh Australian environment, including exposure to moisture, salt, and other corrosive elements. Ruspert coating is a specialized surface treatment for BoldTech Fasteners, designed to provide exceptional corrosion resistance, as proven by its ability to withstand up to 2,000 hours in a salt spray test. This multi-layered coating system enhances the durability and lifespan of metal components, particularly in harsh environments.

3. Performance Testing:

AS3566 outlines a series of tests for dimensional accuracy, tensile strength, and resistance to stripping to guarantee that the screws will perform reliably in their intended applications.

4. Design Requirements:

The standard specifies design parameters for the screws, including head types, thread forms, and drill point shapes, ensuring compatibility with specific applications and ease of use.
