Product Description
Imperial A2 stainless steel internal serrated shakeproof washers to ASME B18.21.1, also known as internal tooth lock washers.
These washers feature serrated teeth around the internal diameter, helping to grip the fastener and mating surface when tightened. They are commonly used to help resist loosening caused by vibration or movement while giving a neater appearance than external tooth shakeproof washers.
Manufactured from A2 stainless steel, also known as 304 stainless steel, they offer good corrosion resistance for general engineering, maintenance, automotive, restoration and outdoor fastening applications.
