A washer is a small component, but one that helps determine the connection. On this page you can read what the washer is for and what to look for when choosing, so you can be sure you order the right size.
What do you use a DIN125A M8 washer for?
A flat washer is placed under the head of a bolt or under a nut. The washer spreads the clamping pressure over a larger surface, so that the material underneath is less likely to be pressed in or damaged. This is especially useful with softer materials and with connections that you loosen and retighten regularly. A flat washer does not secure the connection itself against loosening; separate locking devices exist for that.
Meaning of DIN125A, ZN and 140HV
DIN125A is the standard that defines the dimensions of this flat washer. ZN stands for zinc plated, a zinc layer that protects the steel against corrosion. 140HV indicates the hardness according to the Vickers scale. Zinc plated steel is intended for use in a dry or sheltered environment. For outdoor use or a damp environment, it is better to look at a stainless steel version.
How to choose the right washer size
The washer must match the bolt diameter. For an M8 bolt, an inner diameter of 8.4 mm is needed so that the bolt passes through easily. Also check whether the outer diameter of 16 mm and the thickness of 1.6 mm fit the space you have. Preferably combine the washer with bolts and nuts of the same material and finish, for example the M8 hex bolts listed below under related products.
Frequently asked questions
Which bolt does this washer fit?
This washer is intended for bolts and threaded rods with M8 thread. The inner diameter of 8.4 mm leaves just enough clearance for the shank.
Is a galvanised washer suitable for outdoor use?
The zinc layer offers basic protection against corrosion, but is mainly suitable for dry or sheltered locations. In a damp or outdoor environment, stainless steel is usually the better choice.
What does 140HV mean?
HV stands for Vickers, a scale used to indicate the hardness of a material. 140HV is the hardness class of this washer.
