5. Low Maintenance Due to their corrosion-resistant properties, brass self-drilling screws require minimal maintenance over time. This can be particularly beneficial for installations that are difficult to access once completed.

2. Drill a Hole Using a hammer drill or masonry drill bit, create a hole in the concrete or masonry surface. The diameter of the hole should match the specifications of the anchor.

Another advantage of using galvanised hex head bolts is their cost-effectiveness. While they may be slightly more expensive than regular steel bolts, their long lifespan and resistance to corrosion make them a smart investment in the long run. By using galvanised hex head bolts in your construction projects, you can save money on costly repairs and replacements down the line.
