- jfengel 5y agoI don't get NASA's reasoning. When the bolt is fully tightened, a helical washer is equivalent to a regular one. But if it's even the tiniest bit out, the spring comes into play. Are they saying that it's not really truly locked under that circumstance? That is, compared to adhesives, which really truly don't allow any movement, except perhaps at an atomic scale.
