The Bolted closed puzzle came from Puzzle Master. It is manufactured by Bits and Pieces.

It consists of a wooden base with two wooden uprights attached to it through which a bolt is loosely fed (it is not threaded through the uprights and can slide left and right freely). A nut is threaded roughly centrally on the bolt and is glued or welded into place (it cannot be moved at all). Half way between the uprights are two copper or dowels and lying freely within this contraption is a very large steel ball bearing. No matter how you place the ball and the bolt the ball is firmly trapped. The aim, obviously, is to release the ball.

This is rated as an 8 out of 10 by Puzzle Master (Demanding) which I completely disagree with - I think it is more of a 6 for experienced puzzlers (bearing in mind that their scores begin at 5) and a 7 at a push for novices. A video review of this on YouTube had a kid stating that this was a difficult puzzle but I suspect he was only 10 or 12 years old! If a solution is included I threw it out with the box and doubt you will need it.
