Ah, it is an Allen head.
But from the second pic that I posted, it looks like there’s a cap or something missing??

if you want to put a cap on it, a large diameter vacuum cap cut short would probably work, but there is no reason to cap it.

@TotalyHucked @75gmck25 give you good advice. That is the last screw touched when adjusting the box,it shouldn't need adjustment after initial setup,if it's sloppy something is wrong,worn or the box wasn't setup right to begin with. I posted the factory procedure somewhere in this thread.

If you read the GM shop manual, it is definitely an adjustment point. However, there is at least one other adjustment you do before you touch that allen screw. It’s all explained in the repair manual.

And when you adjust the Allen screw the steering box should be disconnected from the steering linkage, and you should measure the drag with a spring scale to ensure you do not get it too tight.

I have also seen multiple posts where someone adjusted the play without following the manual, and they all seem to have survived. However, you need to be very cautious because in the worst case it could cause the steering box to unexpectedly bind, and possible lock up.
Exactly. That's why I just typically tell people it's not an adjustment at all. 99.9% of people will not do that or even know what a spring scale is lol

That sets the pre-load on the worm gear. It can only be adjusted properly when the box is not hooked up. Did you touch it? You're screwed. Shut the damn hood.
