      thread too short

      Posted by Rick on 10th Nov 2021

      20mm of thread isn't enough, I would usually expect 38mm. As a result I am $20 out of pocket for a useless bolt. Ed: British Standard bolts have quite a short thread length i.e. 2x the diameter. Our bolts are manufactured to the BS standards and our web site specifies the thread length to try to avoid surprises.
