Received a package each of the 10/32 and 12/24 rack screws (Quantity per pack 50). The price was right but it turned out that the screws are not functional.
PROS: Attractive low price.
CONS: The heads on the screws are way too small. They are the size of a regular phillips screw. Normal typical rack screws have an over sized phillips head in order to support and stabilize heavy items on the rack, such as a power amplifier. It would be acceptable if the screws had enclosed black washers, but black washers are not included or available.
I've used about 100 of these screws so far. Rest assured, they are great screws. A little on the soft side but use the right size screw driver (P2 with a dull tip) and you won't have any issues. All the negative reviews are from people who bought the wrong thread screw. Don't give one star because YOU bought the wrong product.
Regarding the user Chris...that dude definitely was using the wrong threaded screw. I once broke off a couple heads because the rack was threaded for 10/32 and I didn't notice. In my defense, the guy before me used 12/24 for all the other gear (what an idiot) and I went off the existing 12/24 screws. Chris most certainly was trying to use the wrong type of screw in the wrong type of rack.
PROS: Cheap Good finish Reusable if you want to Good for aluminum 2 post racks and with cage nuts in 4 post racks
CONS: A bit soft...if you use a sharp screw driver that barely hits then they'll strip a bit
