Squeeeeek No More Counter Snap *At Joist Only* Starter Pack Kit - Part # 3154 The Counter-Snap package includes 50 scored screws, a snap off fixture, a square headed driver bit and complete instructions. We designed the Counter-Snap screws for between the joist to have thread in both boards at the same time. The joist screw won't work between the joist (try O' Berry's 3236) because the separation of thread is greater than the thichness of the hardwood flooring and the subfloor.
