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
