Stripped one of 3 mirror screws


Recommended Posts

So someone hit my mirror and shattered the glass on July 4th which I posted about.

 

I ordered a new one on eBay for $65 (heated) and took out the old one with ease. I put the new mirror in, hand tightened the screws, then used the Allen wrench to tighten the 3 screws. I went through all again to give it a small turn so it was tight and the last one snapped off inside the mirror. I still have the head.

 

The mirror is a little wobbly and it doesn't form a tight seal to the car, so water can now get in.

 

Now what other than spend another $65?

 

Anyone know if I can pop the thing that holds the screw out from the two mirrors and swap that piece? I posted two pics of what it looks like on the old mirror.

Back the broken screw out with whatever method is most familiar and fruitful to you (drill down center of screw, use ez-out, drill out completely and install thread repair insert, etc.) and replace.

 

Good machine shop can do it for you if you've turned in your man card.

I've never done it but would like to try. I don't know what the easiest way to do it is.

 

Edit: is this all I need to do? What setting do I use for the drill? Has 1 or 2, then 1 through 15 on it.

 

That bit is for drywall, will it work?

Another question, if I can get the piece in there out, and I put a new bolt in, will it likely not hold and have stripped the whole thing the bolt goes into? Meaning will the bolt keep spinning once I get the bad one out and I put the new one in? Dealer new bolts for 56 cents.

No the thread on the piece itself should be fine.

I don't know how tight that bolt is in there but if you don't have a rotary tool lying around, Another trick is to superglue something on the bolt so you can grab it with pliers. ... or you could put an elastic in the tip of a screwdriver and try and use that to grab the broken bolt ...

 

Sry but I've been where you are now and it gets hard to think past the rage and discouragement.. lol

Also look at the top picture in my first post. These are allen bolts, so since I was using an allen wrench to tighten it, even if I drilled a flat head top into the broken piece seen in the picture, wouldn't a screw driver not take it out? Before the head snapped off I felt it turn more than it should have.

 

I tried supergluing the head back on and the superglue didn't even work on metal.

You mean hex bolt and rachet? A simple phillps head screwdriver is more than enough to secure those

Second that, use a Phillips screwdriver.

I'm just going to buy three new bolts. I don't know if they were compromised when my mirror was hit two weeks ago. I could not use a regular screw driver to undo them when I first went to remove the damaged mirror. I needed a ratchet wrench.

You can get reverse drill bits that will drill into the screw when the drill is turning counter-clockwise. Once the drill bit gets a bite into the screw, it should back out. Good idea to get all new screws since those probably were weakened.

Those are hex head/phillips head bolts. I use an 8mm socket to remove/install them.

 

No, it's not easy to replace the nutsert (the threaded insert) in the mirror itself. Generally speaking they're inserted into the plastic while it's still hot from being injection molded. They're knurled so if you successfully pull it out, it will remove enough plastic with it that it will be difficult to secure a replacement. . . although it might be possible to glue it back in.

 

As others have said, cut a slot in it or try a left hand drill bit (they are hard to find--you'd probably have to buy a set from someplace like Northern Tool or Harbor Freight or buy a single bit online. The bit you have pictured is a ti-coated and is probably okay but I don't usually buy bits with hex shanks. For drilling metal I like cobalt bits.

 

EDIT:

 

I'll also mention that if there is enough space behind the nutsert, you can just use a normal bit to twist the broken bolt on down into the cavity behind it. No idea how much room is there, use a probe to determine depth.

I will try what you mentioned in your edit since there really isn't much for it to fall through. I just don't know if I can get it out if it falls through then it would rattle inside. I'll also see if any friends have a different drill bit.
