Nut Runner tool for threaded rod

this is designed to be used with a drill and is used to spin nuts up and down on threaded rod much quicker than by hand.it has openings for M12, M10, M8 and M6 threaded rod using an ordinary M8 hex bolt will require some grinding as to round it out for it to fit into the centre spinner as seen in the photos all materials needed are in the photos the tpu cover for the centre spinner can be found on my page UPDATE:the tpu cover does help with slipping when using the nut spinner but after some experimenting and further use ive found that double sided tape and rubber grip tape are a better choice as they offer more grip and less slippage the only downside so far is eventually they need replacing as they will wear down. if theres anything youve found that works well for you please drop a comment and let me know. see how it works by checking out my instagram linked on my homepage please consider rating if you do print this model and check out my page for my other models.
