Spring washer for M4 fasteners: what you need to know

The spring washer DIN127B ZN M4 4.1x7.6x0.9 is a galvanised spring washer for bolts and screws with M4 thread. The dimensions are in the name: an inner diameter of 4.1 mm, an outer diameter of 7.6 mm and a thickness of 0.9 mm. This makes the washer fit the shank of an M4 bolt.

Read more

A spring washer is placed under the head of a bolt or under a nut. Because of its spring force, it keeps tension on the connection, so it is less likely to loosen due to vibrations or changing loads. This makes the washer suitable for machines, installations, structures and assembly work where small fasteners must stay in place.

What does DIN127B ZN mean for this spring washer?

DIN127 is the standard for spring washers. Type B is the version with straight, square-cut ends. The letters ZN stand for galvanized: the steel has a zinc layer as protection against rust. For dry indoor spaces this is often sufficient. In case of moisture or outdoor use, a stainless steel variant is the better choice.

Choosing and fitting M4 spring washer 4.1x7.6x0.9

First check the thread of your bolt or screw. The washer is intended for M4, so a different thread diameter requires a different size. Place the spring washer on the shank, directly under the bolt head or under the nut. Then tighten the connection until the washer is pressed flat. A flat washer can be added to protect the surface of the material, for example with soft materials or thin plates.

Frequently asked questions

Which bolt does this spring washer fit?

This spring washer is intended for bolts and screws with M4 thread. The inner diameter of 4.1 mm matches this.

What is a spring washer for?

A spring washer keeps tension on a fastening. As a result, a bolt or nut is less likely to loosen due to vibrations.

Can I use this galvanized spring washer outdoors?

The zinc layer provides basic protection against rust. For prolonged moisture or outdoor use, a stainless steel spring washer is usually the better choice.

What is the difference between DIN127B and a regular lock washer?

A DIN127B spring washer is split and springs, so it keeps the connection secured. A flat washer mainly distributes pressure and does not secure.
