Hi Dave,
Unless there is physical damage to the pin I see no need to replace it.
There's an old version and a newer version, one being 1/4" longer than the other.
Neither has adequate buried depth length IMO.
What they don't do at the time of installation and that I will now share with you is,
mill, cut, grind or whatever, a relief-slot the length of the buried depth of the pin.
This acts as a key-way for the cured epoxy (being the key).
I do this with all my inserts as well.
The Uni-QR, I slot two sides of the barrel.
1/4" of 7/16x20 thrds holding the insert, especially in wood,
does not overwhelm me with confidence.
Without modification, this insert comes loose more often than any other I'm aware of.
HTHs, KJ
