### 1. Material: 304 Stainless Steel Crafted from 304 stainless steel, these fasteners offer remarkable corrosion resistance. Comprising approximately 18% chromium and 8% nickel, the material forms a passive oxide layer on the surface, protecting against rust and oxidation. This makes them suitable for diverse environments, from humid coastal areas to industrial settings with exposure to mild chemicals. Additionally, 304 stainless steel provides a good balance of strength and ductility, ensuring the fasteners can withstand mechanical stress without breaking while allowing for easy installation and adjustment. ### 2. Flat Head Flange Cross Bolts - **Design Features**: The flat head design of these bolts sits flush with the surface of the fastened material, creating a smooth and aesthetically pleasing finish. This is particularly useful in applications where a low - profile appearance is required, such as in furniture manufacturing or decorative installations. The flange beneath the head serves to distribute the clamping force over a larger area, reducing the risk of surface damage and providing a more secure connection. The cross - head (Phillips head) allows for easy engagement with standard screwdrivers or power - driven bits, enabling efficient and precise tightening while minimizing the chances of the tool slipping off during installation. - **Functionality**: These bolts are ideal for applications that demand a clean look and even load distribution. In machinery assembly, they can hold components together firmly while preventing indentation on the surface of parts. Their corrosion - resistant property ensures long - term reliability, even in conditions where moisture or light corrosive substances are present. ### 3. External Hexagonal Concave Head Screws with Washers - **Screw Design**: The external hexagonal shape of these screws provides a large contact area for wrenches or sockets, facilitating high - torque application during tightening and loosening. This makes them suitable for heavy - duty applications where a strong and secure fastening is crucial. The concave head design helps to center the screw more accurately on the mating surface, ensuring an even distribution of the clamping force and reducing the likelihood of misalignment. - **Washer Function**: The inclusion of washers with these screws offers several benefits. Washers act as a cushion, spreading the load across a wider area and preventing the screw head from digging into the surface of the fastened material. They also help to distribute stress more evenly, reducing the risk of damage to the material, especially when dealing with softer substrates. Additionally, washers can fill any irregularities on the surface, providing a more stable base for the screw and enhancing the overall strength of the connection. In environments where vibration is a concern, washers can help dampen vibrations, reducing the chances of the screw loosening over time. - **Application Scope**: These screws with washers are commonly used in construction, automotive, and industrial machinery. In construction, they can be used to fasten metal framing, structural components, or fixtures. In the automotive industry, they are suitable for engine compartment assemblies, chassis connections, and other areas where reliable and strong fastening is necessary. ### 4. Flat Tail Cross Machine Teeth - **Tail Design**: The flat tail design of these machine teeth provides a stable and secure fit within the tapped hole. The flat surface helps to prevent the screw from rotating within the hole during installation and operation, ensuring that the clamping force is maintained effectively. This is especially important in applications where precise positioning and resistance to rotational forces are required. - **Cross - Tooth Feature**: The cross - tooth pattern on the machine teeth offers enhanced engagement with the mating material. It creates a mechanical interlock, providing a stronger grip and reducing the risk of the screw backing out. This feature is particularly useful in applications subject to vibrations, shocks, or repeated loading and unloading cycles. The cross - tooth design allows for better torque transfer, enabling the screw to hold parts together firmly under various operating conditions. - **Versatility**: Flat tail cross machine teeth can be used in a wide range of materials, including metals, plastics, and wood. They are commonly employed in the assembly of small - scale machinery, electronics, and consumer products, where accurate and reliable fastening is essential for the proper functioning and durability of the final product.
