Review on WELLOCKS Self Drilling Screws M4.2 Pan Head 13-50Mm Length Stainless Strong Tek Screws Self Driller Assortment Kit Set With Storage Box For Attaches Sheet Metal Steel 187 Pcs (D136) by Jason Bell

I recently purchased the WELLOCKS Self Drilling Screws Kit and was largely satisfied with its contents. The storage box was a welcome addition, and the variety of screw lengths allowed for versatility in my projects. However, I found the screws themselves to be inconsistent in quality. While some were strong and effective in drilling through sheet metal, others stripped easily or failed to drill through thicker steel. Additionally, the labeling on the storage box was not very clear, making it difficult to quickly locate the correct screw size. I had to spend more time searching through the box than I had anticipated. Overall, while the WELLOCKS Self Drilling Screws Kit is a decent option for those needing a range of screw sizes for sheet metal projects, I wouldn't recommend relying on it for more heavy-duty steel work.
