2. Application Suitability In environments where higher loads or forces are expected, such as in industrial settings or high-rise buildings, 4% anchor bolts are often preferred. Conversely, 3% bolts may be sufficient for lighter applications, such as residential projects.

- Thread Design The thread design can influence the screw’s holding power. Coarse threads often provide better grip in thicker materials, while finer threads may work better in softer materials.

Furthermore, the widespread adoption of self-drilling screws has contributed to the overall improvement of construction and engineering practices. By streamlining the fastening process and reducing the need for additional tools and equipment, self-drilling screws have helped minimize waste and enhance safety on job sites. This has led to more efficient project timelines and reduced construction costs, benefitting both businesses and clients.

1. Strength and Durability Due to the high-strength material used in their production, M20 bolts can bear heavy loads without deforming or failing, making them ideal for critical structural applications.
