Serrated lock washers Fasteners provide excellent resistance to loosening. Please note that these washers come in two different types - internal toothed and external toothed. And when it comes to loosening resistance, the externally toothed washer does a better job than an internally toothed washer. But the internally toothed washer comes with greater locking abilities. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant. It can also allow the washers to withstand extremely high stress and force.
