High quality metal

The heads don't strip easily when using a standard Phillips screwdriver. Very satisfied with the durability of these fasteners.

Good value, missing a few M6 nuts

Overall a great set with clear labeling. I noticed the count for M6 nuts was slightly lower than expected, but the screws and washers were plentiful.

Perfect assortment for my workshop

This kit has everything I needed for various small projects. The 304 stainless steel quality is evident, and nothing rusted after being left in the garage for a few weeks.

Case latch broke on arrival

The screws themselves are fine, but the plastic storage case arrived with a broken latch. Still usable, just less convenient to organize.

Great for electronics repair

I use the M2 and M3 sizes frequently for repairing computer cases and small appliances. The countersunk head sits perfectly flush.
