![]() ![]() FW fasteners are created without user-selectable pitch, except for the "Threaded Rod" object. TM has none of this, generating only Ext thread shafts and mating Int thread inserts. FW is rich with standardized bolt styles, nuts, washers which are threaded. ![]() Wide variety of bolt heads, washers, nut profiles. using "coarse" pitch standards not available in the FW objects).īut I still wanted to come back to FW to discover all of it's functionality, and made note of 4 basic differences between ThreadMaker (TM) and FW. I've found 0.1 - 0.2 mm radial clearance between mating thread surfaces gives a tight fit at first, but after one run-in fit, they tighten normally and survive lots of re-tightening afterwards (esp. ![]() This clearance is needed in 3d printed threads, because without it, after the curing process, mating printed threads will generate a mean interference fit during tightening, which turns much of the surface material into powder.
