Re: How to Remove a Broken Screw from Mailbox?
Are you about to grab it with needle-nose pliers and then turn it using the pliers?

I tried to use the needle nose but now there is nothing left to grab.

Was the head on the inside and it broke off? Does the threaded hole extend all the way through or does it stop so there isn't access from the other side?
Re: How to Remove a Broken Screw from Mailbox?
Can you use a small file or a rotary Dremel tool to grind a slot on the face of broken screw? Then take a small flat head screw driver and carefully back the screw out?

Re: How to Remove a Broken Screw from Mailbox?
I like onmyway's suggestion about trying to make a slot. That could work well if it isn't too corroded into place. Some people recommend getting a drill bit that bits the opposite direction of normal bits and drilling. They apparently back it out but I have never done this. I have an assortment of screw extractors from Sears that I use with similar problems. Which type to use would depend on accessability of the broken screw and what there is to get grab on to. These tools aren't cheap and usually come in sets so it may not be worth buying a set depending on the cost of your mailbox.

Re: How to Remove a Broken Screw from Mailbox?
3 $teps.
1. Remove entire box from post.
2. Place box in a firm and unforgettable place.
3. Put new box on post.
4. Work on old box until screw is out.
5. Repair. Probably best to replace other hinge so that they wear evenly.
6. Remove temporary new box.
7. Reattach repaired box to post.
8. Garage sale temp box or keep as spare.
Sorry, it was 8 steps. On a tablet and correcting errors is like removing screws.

Drill it out. Use cobalt drill bits, starting with a small diameter ( no more than 1/8 inch). Go slow and use oil. Make sure you are in the center of the old bolt. I don't like screw extractors because the may break, and then you may as well buy a new mailbox. If the end is threaded, then you reach the proper diameter, tap new threads.
Re: How to Remove a Broken Screw from Mailbox?
it is really difficult to suggest a resolution with just one picture...if you had shown a couple of more if may have helped. Is it possible to drill through from the opposite side?....It looks like the box is aluminum...if you drill it out slightly larger you could use a stainless steel bolt with long threads and possibly put a nut on each side to hold it in place...Again, hard to say without better pictures or of the other side that is still not broken....Also, agree with itstoomuch suggestion of removing from post and working on it at a better position.
Re: How to Remove a Broken Screw from Mailbox?
The gainsdirect web site has more pics. But a user pic taken from the right side (as shown in the first photo of this thread) should show the end of the screw in the aluminum (?) threaded hole. Drill the screw out from this right side as described in the previous post. Any handyman could do this for you, too.

Replace with a Fort Knox mailbox. Expensive, but will last generations...
Re: How to Remove a Broken Screw from Mailbox?
I used one of those extrators that hooks to a drill to remove a screw from a door recently and it worked fine. You might also need a flexible adapter if it won't line up.

File a slot. That is the answer.
If you think it is bound, treat it with penetrating oil before trying to unscrew and let soak, with occasional hammer rapping, for several days.
An impact driver is a tool legitimized by this crysis.

An alternative to filing a slot to emulate the most useless screwhead design in history (edit: slotted head) would be to grind two sides, parallel, and then take your pair of 6" Knipex pliers-wrench which everyone surely has (or a small adjustable wrench if that's all you have) and twist it out and hope it doesn't snap. If you have a small butane torch, heat it up before trying to extract it.
Manually grinding a slot might not work here because the screw seems to need a lot of torque to break it loose, and even a precision, factory ground slot for a slotted screw head is not very good at accepting a lot of torque. Grinding the sides so it becomes more like the head of a bolt might allow more torque to be applied. As someone suggested, a few shots of WD40 (or PB Blaster, which I've had better luck with than WD40) and maybe even letting it soak for an hour, might help too. The general problem seems to be the small size of the screw.

Have a plan, stay the course and simplify, but most importantly....Ignore the Noise!

BTW,
You have used WD40 or similar in preparation for extraction?

Re: How to Remove a Broken Screw from Mailbox?
If I had to guess that's a stainless steel screw in aluminum.
In that case heat is your friend. Al expands more than steel. After you've soaked with penetrating oil and filed a pair of flats for grip, apply heat to the outside of the box adjacent to the screw (the right side on your original photo), then try to twist the screw out.
Depending on climate, just bringing it into the house might help. But i'd use a hair drier or heat gun.
Note that it's possible to melt aluminum with a blow torch, so take care if you use one.
Note that most penetrating oils are flammable. Really only a problem if you use a blow torch, but it wouldn't hurt to wipe off any excess before you apply heat.

This post is screwy
What a screwed up situation
If he doesn't fix the mailbox, he'll be screwed
