[DeTomaso] Fw: Re: Stripped bolt hole

[B Hower]

I like the Keen-Sert brand solid insert which has tabs that are at the outer edge of the thing. After it is threaded into position the tabs still protrude outward and are driven in along side of insert, locking the insert so that it can not turn out of the threads.  
 
When I was in the semiconductor industry ( field service ), we used S.S. Keen-serts in phenolic material and aluminum with great success. In this application screws were threaded into the inserts several times a shift.
 
An advantage to Heli-coil is you don't need to over size the original hole as much --- which can allow use where a solid oversize hole would bust out of edge of material.
 
Just another option -------- the last inserts I installed were Heli-coil ( in 351C header location ).
 
IMHO they all have their place.

I'm not a big fan of heli-coils.  I know many people like them, but I don't.

I've used solid inserts with success.  There are many brands.  The kind I
like the most are called Rockmount inserts.  The only place I've found them
are Gessford Machine.  Ask for George.

Timeserts are easier to find, as are other brands.  I recently found a very
good hardware store in Dallas that has all kinds of hardware.  They have
several drawers of solid inserts.

I use Heli-coils, but only because I don't know what a Time-Sert is.  
Can you help me on that one?
