Sigma KEE - MechanicalNut
MechanicalNut

appearance as argument number 1
-------------------------


(documentation MechanicalNut EnglishLanguage "Any object with threads designed to mate with those of a Bolt. This includes any large object with a region that functions as a nut. However, it does not include regions of objects where a screw has created a threaded area and where typically therefore the material is soft enough that retracting and reinserting a screw may create a different thread pattern. This can also be contrasted with regions that are created to be nuts by the use of a MechanicalTap and MechanicalDie set.") Cars.kif 4200-4205
