ISO 4035 (DIN 439) download for SOLIDWORKS

About ISO 4035

Hexagon thin nut, chamfered

ISO 4035 is the standard for the thin version of normal hexagon nuts. It replaces DIN 439, which has been withdrawn decades ago.

The standard consists of 29 unique sizes from M1.6 to M64 and comes in eight materials. The latest revision is from 2012 and you can purchase the standard document from ISO here.

29 sizes * 8 materials = 232 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Many DIN standards for fasteners were withdrawn 30 years ago

European engineers love DIN standards, but most DIN standards were withdrawn in 1992.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Lock and spring washers do not work well so their standards are withdrawn without a replacement.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

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.
