I'm working on strengthening the base of the summer kitchen. Always replace old, damaged rollers with new leveling feet; I need a total of 48 M6-1 metric screws to fit the existing threads on the unit frame. I couldn't find that many "specialty screws" at my local hardware store (and the few I could find were overpriced), so I ordered two packs of flat head steel, zinc plated, JIS B1111 compliant, #3. Phillips Actuator, Thread Size M6-1, Length 50mm, Fully Threaded, Imported (Pack of 10). The screws arrived quickly and correspond to the seller's description. Yesterday I managed to assemble a large kitchen unit using 16 of these screws that are just the right size and thread. I wanted; I damaged the Phillips on one of the first screws I tried with the cordless screwdriver, and for the rest I had to be more careful and use a hand screwdriver. I hope I can use my power tools on them.
