Nordlock Washers - Metric - A4 Stainless Steel

Nord-Lock washers are branded, innovative locking washers that are sold in pairs. In contrast to other types of locking washers, Nord-Lock washers use tension rather than friction to achieve the lock.

Nord-Lock washers have a cam face on one side and radial teeth on the other side. When the matching faces are tightened, the radial teeth grip and lock the mating surfaces, with movement only possible across the cam face. A wedge effect is then created between the cams on the two cam faces that prevent the bolt from rotating loose.

Nord-Lock washers are available in metric or imperial. There are two choices of finishes – choose from A4-316 stainless steel or KL100 zinc flake coating (Delta Protekt).

These impressive fixings outperform all other types of locking washers under strict test conditions. As a result, they are commonly used in a wide range of industries including engineering, construction, manufacturing and rail.

The most common thread type in production today. Usually specified as M then a number x another number. This signifies the thread diameter and the length of the fastener.

For example M4 x 30 means that the major thread diameter (the external distance across the outside of the thread) is 4mm and the length is 30mm. Length is usually measured from the underside of the fastener head.

About A4 Stainless Steel

A4 Stainless is often referred to as 316 or 18/10 stainless. As in A2 above, the numbers 18/10 refer to the chromium and nickel content- 18% chromium and 10% nickel.

A4 stainless is often used in marine or chemical environments as it has greater corrosion resistance than A2.

The chemical composition of both A2 and A4 stainless steel are almost identical with the most notable differences being the higher nickel content and the addition of Molybdenum in A4. Molybdenum is a silvery white metal that is highly corrosion resistant, very ductile and has an extremely high melting point.

There can also be Titanium present in A4 stainless at the option of the manufacturer.

Typically, A4 grade stainless steel costs slightly more than A2 because of its enhanced chemical and production properties. The extra cost can be justified, however, because hardware made of A4 stainless steel is extra resistant to tarnish and corrosion, enabling it to last a very long time.
