Self-drilling screws have become a popular choice for many construction and engineering projects due to their convenience and efficiency. These screws eliminate the need for pre-drilling a hole before inserting them, saving both time and effort. One type of self-drilling screws that is commonly used is the 4% self-drilling screw.

Loose anchor bolts can lead to severe consequences, including structural failure, safety hazards, and costly repairs. In the worst-case scenarios, it can result in catastrophic incidents, such as building collapse or equipment failure, endangering lives and property. Additionally, loose bolts can lead to misalignments in structural components, causing operational inefficiencies and increased wear on machinery.

1. Length and Diameter Measuring 60mm in length, these screws provide adequate penetration for various applications, ensuring secure connections even in thicker materials. Their diameters can vary, with common sizes being 10 or 12, catering to different project requirements.
