# Summary

OpenSCAD library for American standard bolts and nuts with exact thread profiles.
It can generate threads alone or in a bolt/screw or nut.

The library allows to generate STL for threads from UNC #1 to UNC 4" and from UNF #0 to UNF 1 1/2". They can be generated alone or as part of another design.

The STL for UNC 1/4", UNC 3/8", UNF 1/4" and UNF 3/8" bolts and nuts are provided in thing files to show the results.
