M4-0.7 X 55mm 機械螺絲 | 圓頭一字驅動 | 18/8 不鏽鋼 (300 / 包)

The 55mm length is perfect for the thicker brackets I was bolting down, and the 18/8 stainless steel threads threaded cleanly without any binding. I've got a whole tin of these left for future projects since the 300 count is plenty.

Had to replace some old corroded fasteners on a saltwater dock, and these stainless M4s threaded in cleanly without binding. The pan head sits flush enough for what I needed, and the bag had no damaged threads out of the 300 count.

The 55mm length was perfect for the stainless bracket I was mounting, and the 18/8 steel feels solidly built. I've used other screws that strip out easily, but these cut clean threads into the metal without any fuss.
