CD grain screws, also known as cross-directional grain screws, are specialized fasteners designed with a unique thread pattern that provides enhanced holding power and visual appeal. These screws feature a diagonal thread orientation, which sets them apart from regular screws.

One notable characteristic of CD grain screws is their eye-catching appearance. The surface of these screws exhibits a bright and glossy finish, often emitting colorful hues when exposed to sunlight. This stunning visual effect is achieved through the circular grooves engraved during the screw manufacturing process.

To meet the specific requirements of CD grain screws, they are typically fabricated using high-quality materials such as stainless steel. Variants like stainless steel 302, stainless steel 304, and stainless steel 410 are commonly chosen for their strength and durability. Additionally, a careful balance of plasticity is crucial in selecting the appropriate material. This ensures that the screws exhibit optimal performance without the risk of brittleness or excessive adhesion.

Manufacturing CD grain screws involves a combination of precision machining and advanced techniques. Vacuum heat treatment is often applied to modify the material properties and enhance the overall performance of the screws.

CD grain screws find application in various industries, particularly where both functional and aesthetic aspects are important. These screws are valued for their ability to securely fasten materials together while adding a visually appealing element to the finished product. It can be used for mobile phones, three-proof watches, robots, drones, electronic medical equipment, electrical equipment and so on.
