tripletschiee No, these parts are designed for a use in the suspension area of Technic Lego.
tripletschiee The Crossaxle fits as tight as expected (or as "normal" Lego axles).
The female towball needs some movement on a male towball to loose some of its friction.
This is tighter as normal Lego parts, but is no play at all.
tripletschiee Looks rather rough, but works pretty fine and tight.
