Pure Titanium Countersunk Screws

In the field of fasteners that pursue ultimate performance and reliability, Qin Hao brings you "pure titanium countersunk screws". Different from the "titanium alloy" or "straight pure titanium" materials on the market, this product is strictly made of industrial pure titanium (Grade 1 / Grade 2, corresponding to domestic grades TA1 and TA2), which perfectly balances mechanical strength and processing accuracy, and provides the purest "industrial skeleton" for high-end manufacturing.

Many customers have misconceptions about "pure titanium". The industrial pure titanium we use is not unmodified "straight pure titanium", but an optimized material with precise oxygen control:

Enhanced Oxygen Content: By precisely controlling trace amounts of oxygen (rather than adding alloys), the strength and wear resistance of screws are significantly improved while maintaining the purity of titanium.

Superior cold forming capabilities: Industrial pure titanium (TA1/TA2) has better plasticity than straight pure titanium, and can be cold headed to form complex countersunk geometries, ensuring full tooth patterns and no burrs.

Application Orientation: Straight pure titanium is mostly used in laboratories or special scientific research fields, while our industrial pure titanium countersunk screws are specially designed for high-end industrial applications in batches, taking into account performance and supply chain stability.

1. Extremely lightweight

The density is only 4.51 g/cm³, which is about 60% of steel. In weight-sensitive assembly scenarios such as aerospace, racing, and high-end drones, choosing pure titanium countersunk screws means significant weight reduction without sacrificing cross-sectional area.

2. Natural barrier against corrosion

Pure titanium surfaces can instantly form a dense oxide film (passivation film). Whether it is in the marine climate, chemical acid and alkali environment or human sweat erosion, it can maintain zero rust and be maintenance-free for life.

3. Excellent biocompatibility and non-magnetism

As the material of choice for medical implants and precision instruments, pure titanium is non-toxic and completely inert to human tissues. At the same time, pure titanium is a non-magnetic material and is suitable for harsh environments such as MRI equipment and precision electronic equipment.

4. Unique industrial aesthetics (anodized customization)

Pure titanium is a metal that can be colored electrolytically to create artistic effects. We provide anodizing service, which can customize the surface color of the screws (such as gold, blue, purple, rose gold, etc.) according to the Pantone color number. This not only plays a decorative role, but also further improves wear resistance through the thickening of the oxide film.

To ensure the best possible experience, pay attention to the unique mounting characteristics of pure titanium:

1. Grade selection suggestions

TA1 (Grade 1): Superplastic pure titanium with low hardness for thin-walled parts with extremely high forming requirements or extreme cold heading.

TA2 (Grade 2): The main grade of industrial pure titanium, with moderate strength, good plasticity and wear resistance, is recommended as the first choice for standard countersunk screws.

2. Processing and installation warnings

Thread processing: Due to the "sticky knife" characteristics of pure titanium, special taps and cutting fluids are required for thread forming. Our products are precisely rolled to ensure thread finish.

Installing Torque Control: Please note! The coefficient of friction of pure titanium is different from that of steel. It is recommended to set the installation torque at 70% of the same specification steel screws. Over-tightening is the most common cause of slipped teeth.

Anti-electrochemical corrosion: When pure titanium screws are matched with reactive metal sheets such as aluminum and zinc, it is recommended to use them with pure titanium gaskets or apply anti-seizing agents to prevent contact corrosion caused by potential differences.
