    Default Scuttle Removal again and again

    I am in the middle of rewiring the car with a an M-Unit and remote wheel buttons so it means constantly removing and putting the scuttle back on. (She is also my daily driver more on that experience on another post)

    After reading how some members replaced the rivets holding the scuttle to the firewall with screws I did the same and used m3 rivnuts with SS torx screws, the trouble was M3's are tiny, its was time consuming using an Allen wrench on each one.
    With the the constant tightening, removing the socket head started to round out in some so I had to cut a slot and use a screwdriver to remove them.

    My solution was to use a larger M4 knurled thumb screw and it makes things a little easier.
    Still a PIA removing the other bolts this is makes things less time consuming.

    You have such good access that I would consider using M4 or M5 Allen heads. You could then remove them with a cordless drill in 2-3 minutes.

    I used M3 with a nice button head allen bolt on my Locost scuttle. But I also had problems with the rounding as there is so little tool engagement. So I swapped to SS Phillips button heads. Much better and I can remove them with a power tools in seconds. From McMaster Carr you get 100 for $5.

    Another option is to use Torx or Torx Plus head fasteners. They take more torque and repetitive fastening without rounding than hex or Phillips head alternatives.
