حلقات قفل متوسطة مشقوقة مقاس 3/8 بوصة من الفولاذ بأكسيد أسود (200/عبوة)

The black oxide finish made these washers feel really solid and professional during my install, and they sat flat without any twisting. I needed a full 200 count for a project, so getting exactly the right quantity in one pack saved me a second order.

Used a full pack rebuilding an old milling machine and the black oxide finish held up perfectly during installation. The split action sits tight even on well-used threads, so no more worrying about vibration loosening.

Had to replace a bunch of worn-out washers on an old machine and these held up perfectly during reassembly. The black oxide finish gives them a nice consistent look and they fit snug on the bolts without any wobble. I'm stocked on spares now for the next project.
