These drilling screws feature a countersunk head with cross recess and a drilling tail design. Compared to ordinary screws, they offer superior hardness, better retention, and firmer connections. The drilling tail allows direct installation without pre-drilling, significantly improving work efficiency.
| Automotive | High-strength applications including automotive engines, heavy-duty machinery, and bridge construction, preferred for their larger support area and better anti-loosening performance. |
| Mechanical | Used in mechanical, electronic, automotive, and construction fields to connect various mechanical parts, circuit boards, engines, transmissions, and building structures. |
| Energy | For connecting power generation equipment and transmission lines in the energy industry. |
| Architectural | Used in construction engineering, shipbuilding, and petrochemical industry to connect building structures, improve ship navigation safety and stability, and ensure petrochemical equipment safety. |
Screws are indispensable in daily life and industrial manufacturing, often called "industrial rice." Their applications include electronic products, mechanical products, digital products, power equipment, ships, vehicles, water conservancy projects, and chemical experiments.
| Aluminum | Excellent thermal and electrical conductivity but naturally soft. May produce gelatinous buildup after processing. |
| Titanium | EDM machining is well suited for titanium. Requires deionized water as a medium to control heat during processing. |
| Steel | Very strong metal. Generates significant heat during processing requiring precautions. |
| Brass | High tensile strength and easy to machine, but requires slow cutting speed due to softness. |
