Title: need door strike mounting help
Post by: David Anderson on April 30, 2012, 03:33:23 PM
My door latch came loose.  The mounting screw wobbled out.  I can't redrill and make it bigger.  The bolt won't fit through the oval mounting holes in the strike mount bracket.

any ideas on fixing the hole?

Had the same problem on my 5A a few years ago....used what i think is called an anchor bolt? Find the right size that fits into the hole and as you tighten it up the sides expand so it can't pull out.

Maybe a nutsert or rivnut will work in the hole if it's not too big - it's like a rivet with threads inside of it. http://www.cardinalcomponents.com/ (http://www.cardinalcomponents.com/)
Can you get behind it - maybe a nut plate will work?  https://www.pegasusautoracing.com/productselection.asp?Product=MS21047 (https://www.pegasusautoracing.com/productselection.asp?Product=MS21047)

Permatex makes a good product for that but I like the Time Sert or Ezlock method myself but the Permatex holds up and is easy to use

The rivnut idea may work.  This is mouted into the square tubing on the frame, so I'm not sure the ezlok would work.  That tubing is pretty thin.  

On the rivnut application, do I have to buy the tool to install it.  That could end up being a $60 screw hole :o

Must be a lot of stress on that strike, but it did last 12 years.

You can easily make a tool to insert and expand the nutsert or rivnut with a grade 8 bolt the same thread size of the insert, a piece of tubing the same diameter of the top of the insert and a flat washer, as a bearing and a grade 8 nut and some light oil. Thread the nut up the bolt as far as you can then install the washer then the tubing. Then thread this assembly into the insert till the tread is near the bottom of the insert and put it all in the hole, holding the bolt head, tighten the nut toward the insert pressing against the washer and tubing as well as adding light oil for lubrication, which will draw the lower threaded part of the insert toward the bolt head expanding the insert against the wall of the hole you are filling, until it is as tight as you can get it, back off the nut, then unthread your bolt assembly and your insert should be installed. I have the whole tool and set up myself, but have had to do just this method when installing one in a space the tool just would not fit........hope this helps!

Did a little web surfing until i found what i used. Not an anchor bolt but a Crown Bolt Hollow Wall Anchor. Home Depot has them in a package, 25 for $8.30.  Any hardware store should have them in different sizes and amounts, all you need to install them is a screwdriver. ;D

Fixed it.  I went to NAPA for a rivnut.  They sold ez-sert? screw sets.  $140 :o  Yikes, I had to find something less expensive, so I took a 5/16" fine thread bolt, drilled a 5/32" hole all the way through the shaft, threaded it for a 10/32" screw.  I then drilled out the messed up hole in the frame to 17/64", threaded it to 5/16x20, cut the head of the bolt off and made a slot for a flat blade screwdriver and screwed it in flush.  I put the strike back on and screwed in the 10/32 screw and we were done. 

Hopefully, I'm good for another 12 years :)  Total cost about $.50 cents ;D
