Nuts , bolts , and threaded pipes are found in fastenings and fittings in everything from small motor to auto and plumbing system . And they ’re outstanding — until their thread are rusted , crushed , or stripped , and then they ’re useless . At least , Ithoughtthey were useless until I tested a simple - looking shaft calledRotary Thread .

Rotary Thread is n’t a standalone tool — it ’s more like an potpourri of bits designed to be used with a drill or a circular tool , like Dremel . The bit are helpful enough that theRotary Thread Standard Restore Kitrecently won a spot in our challenger to discover the bestnew hand tools of 2024 .

I tried out routine from three differentRotary Thread kits : the Starter Restore Kit , the Standard Restore Kit , and the Master Restore Kit . To test their performance , I gain several bolts and Nut with damaged threads and clamp them securely to my workbench . Then , I fittedRotary Thread bitsin my practice session and Dremel and got fussy furbish up the train of thought . The narrowing edges of the spinning bits quickly ground away rusting and reshaped the grooves in the threads .

Rotary Thread take a leak a mixed bag of bits for specialism filing / smoothen employment , and many of those are pitch towardmechanical repairs , such as rebuilding hydraulic cylinders . But the bits in their Standard Restore Kit are game - changers for anyone who ’s ever had to block off mid - project and consort to the hardware stock because they work into a nut or bolt of lightning with damage threads . With Rotary Thread , restoring the threads to a workable condition is quick and easy .
