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.

Having nuts and washers included saves so much time. No need to run to the hardware store for matching components. Highly recommend.

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.
