Custom Torx Tapping Screw Manufacturer

What is Torx Tapping Screw?

Torx Tapping Screw is a self-tapping screw with a hexagonal star-shaped groove (Torx), mainly used for fixing materials such as metal and plastic. The Torx screw design has a unique hexagonal star-shaped head, which provides higher torque transmission capacity through the contact points of the six corners, reduces slippage, and therefore has better performance than ordinary cross screws (Phillips screw) or slotted screws. This type of screw is often used in fields that require high torque transmission, such as mechanical manufacturing, electronic equipment, construction, etc.

Processing machines and processes for Torx Tapping Screw

1. Processing machines:

CNC Machines: Used to accurately process the shape of the Torx head. CNC machines ensure that the head design of the screw is accurate and flawless, meeting the six-corner shape requirements of Torx.

Automated Screw Tapping Machine: This equipment is used for the self-tapping function of the screw. Through high-precision cutting tools, the screw can freely enter the material being fixed.

Surface treatment equipment: including sandblasting machine, electroplating equipment, blue zinc coating machine, etc., to ensure the uniformity and quality of surface treatment.

2. Processing technology:

Cold stamping: The initial forming of the screw usually uses cold stamping technology. This process can quickly mass-produce high-precision Torx Tapping Screw, especially suitable for standard specifications of screws.

Heat treatment: In order to enhance the hardness and durability of the screw, Torx Tapping Screw usually needs to undergo a heat treatment process. Through the heating and cooling process, the strength and corrosion resistance of the screw are enhanced.

Surface treatment: In order to improve the corrosion resistance and wear resistance of the screw, Torx Tapping Screw needs to be surface treated. Common treatment methods include blue zinc coating, nickel plating, black oxidation, etc.

Torx Tapping Screw Material

Torx Tapping Screw often uses low carbon steel as the main material. Low carbon steel has good processing properties, is suitable for cold stamping and other forming processes, and exhibits sufficient strength in most industrial applications. The advantages of low carbon steel include:

Good ductility: It can be easily cold-worked, reducing cracking problems during the forming process.

Suitable for surface treatment: Low carbon steel can be well treated with surface coating to enhance the corrosion resistance of the screw.

Cost-effectiveness: Low carbon steel material cost is relatively low and suitable for mass production.

Precision and surface treatment

1. Precision:

Torx Tapping Screw has very strict precision requirements. According to different standards, such as JIS, ANSI, DIN, BSI, etc., the dimensional tolerance of the screw needs to be controlled within an extremely precise range. Specifically for this screw, the standard specifications include:

Nominal length: L12mm±0.1, L4mm±0.1

Nominal diameter: 3mm±0.05

This precision requirement ensures the compatibility of the screw on different equipment and the reliability of application.

2. Surface treatment:

Torx Tapping Screw is surface treated with Blue Zinc Plating. The main advantages of this treatment include:

Corrosion resistance: Blue Zinc Plating effectively prevents the screw from rusting due to contact with air or moisture, and is particularly suitable for humid or highly corrosive environments.

Aesthetics: Blue Zinc Plating not only provides protection, but also has a good appearance, making the product more visually attractive.

Good wear resistance: The plating increases the surface hardness of the screw and extends its service life.

3. Salt Spray Time:

After surface treatment, Torx Tapping Screw also needs to undergo a 48-hour salt spray test (Salt Spray Time: 48 hours). The salt spray test simulates the corrosion resistance of the screw in a high humidity and salt environment. This test ensures the long-term stability of the screw in actual application, and is particularly suitable for applications in marine, coastal areas or highly corrosive environments.

Torx Tapping Screw performs well in many fields, especially in the following aspects:

Enhanced torque transmission: Due to the hexagonal star design of the Torx head, it can better transmit torque and avoid damage to the traditional screw head due to excessive torque. Such a design is very important in high-precision and high-load applications, such as fixing parts in the automotive industry.

Self-tapping function: Self-tapping screws can directly enter the material without pre-drilling, reducing processing time and improving production efficiency.

Wide material compatibility: Suitable for a variety of materials such as metal, plastic, wood, etc., especially suitable for use in hard materials such as aluminum alloy, steel, ABS plastic, etc.
