حلقات قفل داخلية مسننة 5/8 بوصة | فولاذ مقاوم للصدأ 410 (100 / عبوة)

These 410 stainless lock washers held up perfectly when I used them on a wobbly garden cart axle. The material feels solid and corrosion-resistant even in damp conditions. Exactly what I needed to stop those bolts from backing out.

I had to replace some loose fasteners on a shed door that gets a lot of wind vibration, and these lock washers held tight perfectly. The 410 stainless steel feels sturdy and didn't rust during a recent rain. Really glad I grabbed this pack for the price.

Used a few of these on a project that sees constant vibration, and they haven't budged at all. The 410 stainless steel feels sturdy and didn't rust even after being exposed to some moisture. Exactly what I needed for the #5 size fasteners.
