Enerjet by Aerotech, Astrobee D Build, Part 11, Forward Lug Rail Fastener

Here's the bolt placement pattern.

The arrow points to the outside. The bolt rows aren't at the center but are a little closer to the inside vertical bar.

I've extended the center lines with pencil.

Set the pattern inside the fastener and to the side to make pencil placement marks.

Extend the pencil marks across the base.

Mark the vertical center lines.

A drop of medium CA glue was set on scrap cardboard.

Use tweezers to hold and position the bolts.

Dip the flat bottom in the CA glue, touch the bottom on the cardboard to remove the excess glue.

Set and center the three inside bolts first.

To make a CA glue fillet,

Dip a toothpick into the drop of CA. Wipe off the excess.

Run the glued tip around the sides of the bolt already in place. Don't use much glue.

Set the two outer bolt heads and fillet.

Here's how the bolts sit, three inside in one line,

Two outside bolts in a line.

Repeat on the other side.
