    A:  If you are using the metal handrail the posts slide into a groove at bottom of rail and clamp on. If you are using wood handrail the posts come with wood screws in the package. Look for them in bedded in the foam at base of post (If I remember correctly).

      Q:What tool do I need to screw this type of screw?

      Answer This Question

      A:  You will need a drill to pre drill the holes. Do not make hole too large or screw won't hold. Make sure there is plenty of secure wood (thick) to screw into or the post will be loose and unsafe. Use a socket and ratcheting socket wrench to turn in screws. Plastic cap presses on by hand after screw is in.

        A:  You need a hex bolt to screw this in.

            A:  No. The cap is a gray plastic material that matches the color of the mount that holds the railing post.

            Recommend using the Prova anchors with the Prova system so that the heads fit the openings in the attachment, It can be hard to find equivalents in the average hardware store. You can configure your system on the Prova website with their project designer - a good way to make sure you have all the pieces you will need. http://alu.provasystem.com/en/
