DIN 981 download for SOLIDWORKS

About DIN 981

Lock nut

DIN 981 is the standard for lock nuts, to be used with lock washers from DIN 5406.

It consists of 47 unique sizes from size KM0 to KM 40 and KML 24 to KML 40 and comes only as plain steel. The latest revision is from 2009, which you can purchase from DIN here.

47 sizes * 1 material = 47 files

DEMCON has over 100 engineers that make use of the 3D models from CAD Booster and the response has been great. The hodgepodge library from the past is replaced by a consistent set of models, which saves us time and money.

Native SOLIDWORKS models

You receive a ZIP file with a folder for each material, every folder contains all sizes. Each part has one configuration and every part contains mate references, cosmetic threads, custom properties and a material. Download samples below.

ISO replaces DIN

Many DIN standards for fasteners were withdrawn 30 years ago

European engineers love DIN standards, but most DIN standards were withdrawn in 1992.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Lock and spring washers do not work well so their standards are withdrawn without a replacement.

The best fastener library

We create high-quality, high-performance fastener models for SOLIDWORKS.
  • We create our fasteners using battle-tested software
  • Extremely consistent native SOLIDWORKS models
  • All files have mate references and custom properties
  • No more mate errors when you switch between types
  • One configuration per part; the most robust option
  • Dumb files, so fully compatible with PDM and 3DEXPERIENCE

Our 3D models + Lightning = magic

Lightning is the add-in that makes working with fasteners fun again.

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.
