hexagon self drilling screw

One of the key advantages of self-drilling screws for heavy steel is their ability to save time and labor costs. Traditional screws require pre-drilling a hole before fastening, which can be time-consuming, especially when working with heavy steel materials. Self-drilling screws eliminate the need for this extra step, allowing for quick and efficient installation. This is particularly important in industrial settings where production timelines are tight and every minute counts.

The heavy hex head bolt consists of a threaded shank and a large hexagonal head, which provides a larger surface area for better grip and torque transmission. The head design also prevents the bolt from turning during installation, ensuring a secure fit. The thread pitch and diameter of the bolt are crucial factors that determine its mechanical properties, such as tensile strength and shear strength. Generally, heavier bolts have greater strength due to their increased material volume.
