How to remove what I think is a screw head caught in a waste disposal

Question

I have a waste disposal, and what looks like a screw head, which is jammed in the waste disposal unit (an Insinkerator 55 if it matters).

This means as the machine is turned on, it makes a banging noise as the 'blades' hit it. I'd like to remove this obstacle but it's jammed tight.

The problem is, the angle. As per this image (red X shows where the screw is)

You can see, the sink is at the top and then insinkerator is below, but the angle of the hole means I'm limited to what I can get in. The screw head is fairly flush, I can't really 'grip' it with pliers and when I do, it doesn't really budge.

I have been whacking at it with a chisel and hammer, and it won't move (hoping to snap the metal) !

I've tried using a dremel tool and attempting to 'sand' or 'file' it away, but are there any other options for situations like this (other than replacing the entire unit).

I also don't seem to be able to take the unit apart so it appears as if my only option is from going in from the top!

Answer 1

In the end, I kept on sanding it down (sanding and cutting with a dremel) until it eventually became thin enough I could crack it (snap it) with a chisel.

Answer 2

In case this happens to anyone else. I used a flathead to loosen around the screw just prying. Then I got a Phillips drill bit and put my hand in and unscrewed the screw.

Answer 3

Get yourself a flexible claw gripper to fish it out. It'll work wonders.
