1.Countersunk Head Design
The countersunk head allows the screw to sit flush with the material surface after installation, providing a clean and smooth finish.Ideal for applications requiring a sleek surface, such as furniture and architectural decoratio |
| 2.Reinforced Ribs Ribs under the head enhance the self-tapping ability, making penetration into materials easier while reducing the risk of thread stripping. Improves locking strength, ensuring a more secure connection. |
|
| 3.Self-Drilling Tip The drill point allows for direct penetration without the need for pre-drilling, significantly increasing installation efficiency. Suitable for fastening metal-to-metal, metal-to-wood, and other material combinations for quick and stable installation. |
