Review on SZHKM 150PCS M6 Kit Crib Screws Hardware Replacement Kit Hex Socket Head Cap Screws Nuts Zinc Plated M6 Screws Barrel Screws Furniture Screws And Bolts Assortment Kit For Baby Bed With Free Tools by Robert Chandrasekar

The screws seem to be a good quality, I haven't seen any unthreaded nuts or bolts and a neodymium magnet test shows they're only slightly magnetic, which is indicative of stainless steel. However, the nuts were scattered all over the box so I had to take time with a set of tweezers to re-sort them. Annoying, but not much else.
