Weak screws, snapped tapping into aluminum. Terrible 'self drilling'.

These screws are really weak. The 'drill' end struggled to get through thin aluminum panel. Once threads caught, the screw snapped in half. Managed to only use them when drilling a pilot hole.

Pros
  • Assortment Kit
Cons
  • Rusting Possibility: While the screws are made from stainless steel, there is still a possibility of rusting over time if they are exposed to moisture or harsh weather conditions. This could diminish their strength and effectiveness over time

Additionally, the labeling on the storage box was not very clear, making it…
