Transmission plug hole got stripped or cross-threaded, so I used a piggy back plug to fix it. The smaller plug comes with an o-ring on it that is worthless. Take it off and get a brake washer like the one I used. Just making the small plug hand tight would force the o-ring to deform and push out the side. Not sure why it even comes on there.

High tensile bolts Single Point threading to a reduced size.
I have machined down these 1/2″ diameter long bolts to 3/8 inch. and am cutting the new threads in 3 passes with Kennametal 60 degree threading inserts 2 roughing and one finishing pass @ 460RPM. I couldn’t use my geometric head because I don’t have this size dies.
