Frequently Asked Questions

What is a DIN 125 washer used for?

DIN 125 washers are used to distribute load under a bolt or nut and prevent damage to the surface being fastened.

What do d1, d2, and s mean?

d1 is the inner diameter, d2 is the outer diameter, and s is the washer thickness.

Are DIN 125 washers metric?

Yes, DIN 125 washers are metric standard washers designed for use with metric fasteners.

What is the difference between DIN 125 and other washer standards?

DIN 125 defines standard flat washers, while other standards may specify different thicknesses, tolerances, or heavy-duty variants.

Why are washers used with bolts?

Washers help distribute load, reduce friction, and prevent loosening or surface damage.


Flat washers such as DIN 125 are commonly used in construction, automotive, and general engineering applications where reliable fastening and load distribution are essential.
