Drilling Screws

Hexagonal Drilling Tail Screw Manufacturers

A drill tail screw is a screw with a special tail design, and its tail is in the shape of a drill tail or a pointed tail. This design allows the end-drilling screw to be drilled, tapped, and locked directly on the setting material or base material without auxiliary processing. Compared with ordinary screws, drill tail screws have the following advantages:
Save construction time: Since the drill tail screw can be directly drilled, tapped, and locked on the material, there is no need to pre-drill or use screw-cutting tools, which greatly reduces the construction time and steps.
High toughness and retention: The special design of the drill end screw makes it have high toughness and retention after combination. This means that the screws are less likely to loosen even after prolonged use, providing a more reliable connection.
Ease of operation: Drilling, tapping, and locking operations are very simple with drill screws. Since no additional tools or steps are required, all operations can be completed at one time, which improves the efficiency of construction.
In a word, through its special tail design, the drill end screw saves time in construction, provides high toughness and holding force, and is easy to operate. These features make drill tail screws a valuable screw option for many applications.

Industry Introduction

What are drilling screws, and how do they differ from regular screws?
Drilling screws, also known as self-drilling screws, are a specific type of fastener designed to drill their own pilot holes as they are driven into a material. These screws combine the features of a drill bit and a screw, eliminating the need for pre-drilling a hole before inserting the screw. They are widely used in various applications, especially in metal-to-metal or metal-to-wood fastening.
Here's how drilling screws differ from regular screws:
Self-drilling capability: The key difference is their ability to create their own pilot holes while being driven into the material. Regular screws require a pre-drilled hole to avoid splitting the material, whereas drilling screws have a built-in drill bit at the tip that can bore through the material during installation.
Tip design: Drilling screws have a specially designed drill-like point at the end of the screw, often called the drill point or drill tip. This drill point is usually made of a harder material, such as hardened steel, which enables it to cut through the material being fastened without the need for a separate pilot hole.
Threads: Like regular screws, drilling screws have threads that allow them to create a secure hold within the material. The thread design can vary based on the type and application of the screw.
Material compatibility: Drilling screws are commonly used with materials like metal, wood, and some types of plastics. They are particularly popular in metal-to-metal applications due to their ability to drill through metal surfaces.
Efficiency: The self-drilling capability of these screws saves time and effort during installation, making them more efficient for various projects.
Different types: Just like regular screws, drilling screws come in various types, including pan head, flat head, hex head, and more. Each type is suitable for specific applications, offering versatility in their usage.
It's worth noting that while drilling screws are convenient and effective for certain applications, they may not be suitable for all scenarios. For instance, in some delicate or brittle materials, pre-drilling a pilot hole might still be necessary to avoid damage or splitting.

What materials are drilling screws typically made of?
Drilling screws are typically made from various materials, depending on the specific application and the properties required for the screws' performance. The choice of material affects factors such as strength, corrosion resistance, and suitability for different environments. Some common materials used to manufacture drilling screws include:
Carbon steel: Carbon steel drilling screws are commonly used for general-purpose applications. They offer good strength and are cost-effective. However, they may not have high corrosion resistance, so they are often coated or plated to enhance their durability.
Stainless steel: Stainless steel drilling screws are preferred for their excellent corrosion resistance. They are particularly suitable for outdoor or marine applications where exposure to moisture and harsh conditions can cause rusting or corrosion. Stainless steel comes in different grades, with 304 and 316 being popular choices for drilling screws.
Alloy steel: Alloy steel drilling screws are made from steel combined with other elements to enhance specific properties, such as strength and toughness. These screws are commonly used in applications that require high tensile strength or resistance to extreme conditions.
Aluminum: Aluminum drilling screws are lightweight and offer good corrosion resistance in certain environments. They are often used in applications where weight is a concern, such as in aerospace or automotive industries.
Brass: Brass drilling screws are known for their corrosion resistance and attractive appearance. They are commonly used in decorative or marine applications where aesthetics and resistance to corrosion are essential.
Zinc-plated steel: Zinc-plated drilling screws have a layer of zinc coating to improve corrosion resistance. They are cost-effective and suitable for indoor applications or environments with mild exposure to moisture.
Galvanized steel: Galvanized drilling screws have a thicker zinc coating than zinc-plated screws, providing better protection against corrosion. They are commonly used in outdoor applications, construction, and roofing.
Titanium: Titanium drilling screws are lightweight, strong, and highly corrosion-resistant. They are often used in industries where high strength-to-weight ratio and corrosion resistance are critical, such as aerospace and marine applications.
The material chosen for drilling screws depends on factors like the environment in which they will be used, the materials being fastened, the required strength, and the budget for the project. It's essential to select the appropriate material to ensure the longevity and performance of the screws in the intended application.
