            I used them to fasten down a headache rack on my semi. The package of assorted washers and nuts came in handy!

            They get the job done nicely
            I purchased these to complete some heavy metal compression plates in order to press mending plates into wood for trusses. Using a jig that I built, I tightened them onto threaded rod using an impact wrench and they worked without the nuts rounding out or any other issues.

            Matches perfectly with the 1/4" threaded rod. Perfect for the job at hand!!

              Bought 4. Returned 3. Return person was flumuxed and brought out a tape measure even though this product is sold individually with yellow painted ends. Got ripped off that way, and received less money than I paid. I do not like HD New Milford CT.

              Great kit, seems very handy BUT it wasn't marked or labeled the size of the thread whether coarse or fine. Bought it, returning it tomorrow. Wrong thread.
