4. Reduced Vibration and Shock Sensitivity Since they engage with the substrate through adhesive rather than mechanical means, they tend to be less sensitive to vibrations and shock loads.

4. Corrosion Resistance Many wafer head reamer self-drilling screws are available with protective coatings, such as zinc plating or galvanized finishes. These coatings increase resistance to rust and corrosion, extending the lifespan of the fastening solution.

3. Aesthetic Appeal The flush finish of countersunk screws provides a clean and professional appearance. This is particularly important in applications where the visual aspect is significant, such as in furniture making or cabinetry.

5. Nut and Washer Compatibility When using M20 bolts, it’s crucial to pair them with corresponding nuts (usually M20 nuts) and washers. This combination ensures a secure fit and distributes the load evenly, minimizing the risk of loosening over time.
