ISO 8673 (DIN 934) download for SOLIDWORKS

About ISO 8673

Hexagon regular nut

ISO 8673 is the standard hexagon nut, but with fine threads. It replaces DIN 934, which has been withdrawn. ISO 4032 has coarse threads.

The standard consists of 24 unique sizes from M8x1 to M64x4 and comes in eight materials. The latest revision is from 2012, which you can purchase at ISO here.

24 sizes * 8 materials = 192 files

Properties: Fine pitch, ISO, Nuts

Materials in this download: Stainless steel A2-70, Stainless steel A4-70, Steel 10 plain, Steel 10 zinc, Steel 6 plain, Steel 6 zinc, Steel 8 plain, Steel 8 zinc

SOLIDWORKS version:

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Many DIN standards for fasteners were withdrawn 30 years ago

European engineers love DIN standards, but most DIN standards were withdrawn in 1992.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Lock and spring washers do not work well so their standards are withdrawn without a replacement.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