    3. T20 bits and screws, what am I doing wrong?

      ~life.home_improvement Ask (advice)
      I am putting a new surface on my Deck. I am using Trex and 2.5" composite specific screws. These are small head screws with a T20 torx bit. [img]https://i.ibb.co/MchtXPx/20230628-175119.jpg[/img]...

      I am 7.5 boards in out of 25 boards and I have destroyed 5 bits, 3 of them brand name impact rated bits. I am making sure to stay cammed in, and weight on top of the screw. I am lining the drill up with the angle of the screw. I am also predrilling every hole.

      I feel like I have to be doing something wrong. I just don't know what else to do.

      Edit - these are the exact screws I am using - https://www.homedepot.com/p/Grip-Rite-9-x-2-1-2-in-Brown-Star-Drive-Pan-Head-Coarse-Composite-Deck-Screw-10-lbs-Pack-N212CSB10BK/207193648

    42. What are the differences between the Autobahnen and the Interstate Highway System?

      I know there are some Germans on Tildes, figure at least one of y’all might know. How does a typical Autobahn differ from a typical Interstate in design and construction? How often is repair work...

      I know there are some Germans on Tildes, figure at least one of y’all might know. How does a typical Autobahn differ from a typical Interstate in design and construction? How often is repair work done and how long does it last? What work would be required to upgrade an Interstate to Autobahn standards?
