The Micro Internal Lock Washer is created to DIN 6798J standard and are also known as ‘toothed lock washers’.
These washers have teeth or serrations on the inner face of the washer that bite into the surface that it is used on. However, it does not provide as much holding power as a similar external locking washer.
Toothed lock washers are most effective when used on softer materials such as Aluminium or Plastic.
The Micro Internal Lock Washer is manufactured as standard in A2 Stainless Steel and Spring Steel, with some sizes also available in A4 Stainless Steel.
Available from Fastenright in diameters ranging from M2 to M3 as standard.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
