Products Description
Hexagonal Flange Round Head Cross Recessed Threaded Tooth Self-Tapping Screws are high-performance fastening solutions designed for applications that require durable, secure, and efficient installation without the need for pre-drilling. These screws feature a hexagonal flange for enhanced grip, a round head for a neat appearance, and a cross-recessed drive for easy installation. The threaded tooth design ensures excellent hold in a variety of materials, while the self-tapping feature allows them to create their own mating threads as they are driven into the substrate.

Products Process
Material Selection: The raw materials used for production are typically high-quality carbon steel or stainless steel, chosen for their strength, corrosion resistance, and durability.
Cold Heading: The screw blanks are formed using a cold heading process, which involves pressing metal into the desired shape under high pressure. This ensures uniformity and strength in the body of the screw.
Thread Rolling: The threads are created through a cold rolling process, which enhances the screw's durability and reduces material waste. This method ensures the threads are precise and can effectively grip into the material being fastened.
Heat Treatment: The screws undergo a heat treatment process to improve their hardness and tensile strength, ensuring they maintain their structural integrity under stress.
Surface Coating: A protective coating (such as zinc plating or black oxide) is applied to prevent corrosion and extend the screw's lifespan, making it suitable for outdoor and industrial use.
Assembly & Quality Control: The screws are then assembled with their hexagonal flanges and round heads, followed by thorough inspection to ensure they meet quality standards for size, strength, and thread integrity.

FAQ
What materials are used for these screws?
These screws are commonly made from high-carbon steel, stainless steel, or other materials based on customer requirements. Stainless steel versions offer increased corrosion resistance for outdoor or marine applications.
What sizes do these screws come in?
We offer a wide range of sizes, typically from M3 to M10 in diameter and lengths ranging from 10mm to 100mm. Custom sizes can be produced upon request.
Can these screws be used for outdoor applications?
Yes, these screws can be coated with zinc plating or other corrosion-resistant coatings to make them suitable for outdoor and harsh environmental conditions.
How do I know if the self-tapping screw will work for my application?
The self-tapping design is effective for materials like wood, plastic, and thin metals. If you're working with harder materials or thick metals, we recommend checking the required torque and ensuring that the screw's material and coating are appropriate.
Can I use these screws in electrical applications?
Yes, these screws are commonly used in electrical equipment, but always ensure that the coating and material are appropriate for the specific electrical environment (e.g., non-conductive coating if necessary).
Do these screws require a pre-drilled hole?
No, these screws are self-tapping and can create their own threads in most materials, eliminating the need for pre-drilling in most cases.
Are custom coatings available?
Yes, custom coatings such as black oxide, nickel plating, or other specialty coatings can be applied based on the needs of your project.
How do I install these screws?
These screws are designed for easy installation using a cross-recessed screwdriver or power drill. The cross-recessed drive allows for efficient torque application.
Can I request samples for testing before placing a bulk order?
Yes, samples can be requested for testing and evaluation before committing to a large order. Please contact our sales team for more details.
