Review on Uxcell Flange Bearing Thickness Bushings by Aaron Thawngzauk

I bought these hoping to use them to repair an accidentally damaged petrol tank. I had to do a bit of sawing and grinding to get the inside diameter from 10mm to 10.2mm for tapping (I'll buy taps from the same shop) and so far so good. The black dots on the piece are holes that have been filled with material (obviously on purpose), but I ended up drilling them out, which is incredibly easy
