fasteners

A Cadova library providing customizable threads, screws, bolts, nuts and related parts.

A quick way to create nutcatches, screw holes and countersinks in CadQuery, according to fastener standards.

Utility for creating, organizing and sharing standard parts for your Solid Edge project

Generate print-ready labels for your Gridfinity storage — fasteners (screws, nuts, washers) with 200+ ISO/DIN standards, plus custom labels. SvelteKit web app.

Suzuki Fasteners Registry

This project allows you to download CAD files in `.STEP` format. Currently, the app supports various types of gears, bearings, and fasteners.

Clean-room, MIT, printable OpenSCAD screw threads (ISO metric + Unified): bolts/nuts/washers, tapped/clearance/countersunk holes, augers, Phillips & hex drives, custom flank angle, taper, standoffs, couplers.

Preload based fastener torque analysis for bolted joints, in a single HTML file. Derives installation torque from a target preload instead of a lookup table, checks margins against fastener yield, thread strip, head bearing, joint slip and self loosening, and prints a paginated schedule. No build, no dependencies.

GUI for designing nonpermanent assemblies

Web-based parametric CAD generator for rapid hardware prototyping. Interactively configure mechanical parts (fasteners, bearings, springs, linear motion) and export 3D models or FreeCAD Python scripts directly in your browser.

This project promotes the concept of Design as an API: a mechanical design toolkit using JSON-driven solvers to automate textbook machine design calculations.

Support and documentation for DRH - Mechanical Component Builder, a Blender hard-surface hardware toolkit currently in development.
