Name that fastener
Dont ever try and use them in a "blind" hole, you will break the install tool.
Same goes for small gauge inserts, dont use 10-32, 1/4-20 in anything other than sheet metal or you will pop the end off the tool. Even 1/8" is to thick for the small size inserts.
When you snap off then ends order new ones off E bay.
Also make sure to double crush them. Crush once then tighten up the tool and re crush. It sucks when one spins.
Trust me.....
