| Type | Truss Head Self-Tapping Screw | A screw with a truss head that can form its own thread in a pre-drilled hole without tapping. |
| Head Style | Truss (Hollow) Head | A hollow head designed to reduce weight and increase torque efficiency. |
| Drive Type | Phillips, Slotted, Hex Socket, etc. | The type of drive mechanism used for installation, commonly Phillips for self-tapping screws. |
| Material | Carbon Steel, Stainless Steel (e.g., 304, 316), etc. | Material affects the screw's strength, corrosion resistance, and appearance. |
| Grade | Various grades such as 4.8, 8.8, 10.9, etc. | The grade indicates the screw's mechanical properties and load-bearing capacity. |
| Diameter (d) | Common sizes range from M2 to M12 | The nominal diameter of the screw thread. |
| Length (L) | Varies depending on application, typically from 5mm to 200mm | The overall length of the screw, including the threaded and unthreaded portions. |
| Thread Pitch (P) | Coarse, Fine, or Extra-Fine, e.g., 0.5mm, 0.75mm, 1.0mm, etc. | The distance between threads, which affects the fastening grip. |
| Thread Type | Self-Tapping Thread | The type of thread that the screw has, which can be standard or designed for specific materials like wood or metal. |
| Application | Used in various applications such as automotive, machinery, electronics, construction, etc. | The industries and applications where the screw is commonly used. |
| Load Capacity | Rated based on material, grade, and dimensions | The maximum load the screw can withstand before deformation or failure. |
| Temperature Range | Varies by material; e.g., -60°C to 300°C for stainless steel | The temperature range within which the screw can safely operate without loss of strength or corrosion resistance. |
| Finish | Zinc Plated, Black Oxide, Phosphated, etc. | The surface treatment applied to the screw for corrosion protection and aesthetic purposes. |
| Customizability | Available in custom sizes, materials, and finishes | Ability to produce screws to meet specific customer requirements, such as unusual sizes or specialized materials. |
| Standards | Adheres to international standards such as ISO, ASTM, GB, etc. | The manufacturing and testing standards to which the screw is manufactured and tested, ensuring quality and reliability. |
| Special Features | Flat Tail, Plum Blossom Point, Semi-Countersunk Head, etc. | Unique features that may include a flat tail for flush seating, a plum blossom point for easier starting, and a semi-countersunk head for a lower profile. |
