It consists of 88 unique sizes from 8 to 300mm and comes in three materials. The latest revision is from 2017. You can purchase the standard from DIN here.
One-time investment. No maintenance fees.
88 sizes * 3 materials

European engineers are fond of DIN standards, buy many DIN standards for fasteners were withdrawn in 1992. Most of them have an ISO replacement.
We only offer fasteners for active standards because we purchase the standard document and use it as a source for our fastener models.
Lock and spring washers like DIN 125 and DIN 6798 have been withdrawn without an ISO replacement, most likely because they don't work well.
We were tired of scrolling through endless lists of fasteners in SOLIDWORKS, so we built Lightning. Lightning makes it easy to add, edit and replace fasteners.
Just open the filter, pick a type, size and material, then drag the file into your assembly. Lightning will add a washer and/or a pattern for you.
