#4 غسالات قفل داخلية | ستانلس ستيل 18-8 (400 / عبوة)

The box of 400 lasted through all the small fasteners on my project, and the stainless finish hasn’t shown a single spot of rust after a humid week. They bite into the surface just right, holding tight even when I ran the drill in reverse to test them.

Used these #4 lock washers on a vibration-prone machine mount and they held tight even after hours of run time. The 18-8 stainless feels durable and corrosion-resistant, which is exactly what I needed.

Had to redo a small electronics project after the original hardware rusted, and these stainless steel washers are perfect—the internal teeth really grip well under vibration. Four hundred washers in one pack means I won't run out anytime soon.
