Threadning...

At the time of the idea and design, the artist must have
felt pretty screwed...

But it's still a good idea, when you nailed something and it won't stick
to think of another way to keep it in its' place...
Why don't you screw it...?They come in all shapes and sizes.
Bold headed, flat headed even with a cross or do I say Philip shead.
Notice the thread running down its' side, allll the way down...

So if nailing isn't good enough, you have to screw it...!!!
