    HOw often do I need to put screws in my top cap for my deck railing?" I want to make sure it looks nice, so I don't want to put in too many.

    My cap is a 2x4 layed flat. It sits on the top rail which is also a 2x4. If I chose to screw from underneath I would have to toenail each screw. Not sure if that is the best way or not. I read some other sites that said every
    12" , but that seems like an awful lot of screws to have to look at.

    I would stick with 12" but no more than 16 forsure and no, no toenails.

    So if you say no to the toenails, is there another way to attach the cap rail from the bottom?

    To give you a better picture, the cap rail is centered over the top rail.

    Drill a countersink hole through ~2/3 of the 2x4

    Put a washer sized to your countersink hole under the screw head and run them up from underneath.

    I'm sure you already have the railing in place, so you'll get to lie on your back and enjoy staring up at the sky while you do the drilling. If not, just flip it over and pre-drill and countersink every ~12"

    Good idea Kerrylib, This is all I could think of to exept for screwing down from the top and pluging the holes afterwards.

    May I ask what is bad with toenailing from the top rail to the cap rail from underneath?

    I don't know of any specific arguments that toenailing is bad, but just thinking about it:

    1. Pain in the butt factor
    2. Personnaly think it looks bad.
    3. Limited strength if you don't do it well.
    4. Running the screws in at angle is going to want to pull the top cap sideways and probably twist it from sitting flat. Solution would be to clamp it down tightly when installing screws and attach screws from both sides. This would help negate #3 above.
