1. Dimensions The M20 foundation bolt has a diameter of 20 mm and typically comes in various lengths, depending on the required application. The length can range from 50 mm to over 200 mm, and it’s essential to choose a length that suits the thickness of the material being anchored.

The self-drilling tip, which distinguishes these screws from standard screws, allows them to penetrate through various materials, including metal and wood, without pre-drilling. This feature is particularly advantageous when working with thinner gauge metals or materials where traditional drilling would be cumbersome or time-consuming. As a result, projects can proceed more smoothly, with fewer tools and less disruption.

3. Longevity and Durability The robustness of stainless steel foundation bolts means they require less frequent replacement and maintenance compared to their carbon steel counterparts. This longevity translates to cost savings over time, as less money needs to be spent on repairs and replacements.

Moreover, DIY enthusiasts use self-drilling screws in home repairs and renovations due to their user-friendly nature. Whether it's installing a shelf or building a garden shed, these screws are invaluable for ensuring a reliable and robust assembly.

Self-drilling galvanized screws are widely used in various sectors, including construction, automotive, and manufacturing. In the building industry, they are commonly employed for securing metal roofing panels, fastening siding, and assembling metal framing systems. The screws are also ideal for use in HVAC systems, where durable and reliable fasteners are crucial for maintaining system integrity.
