Bottom of heatbed M3x8r receiver has bad thread

The bottom left (looking at the bottom of the bed when it is upright) M3x8r receiver has a bad thread. I noticed it when I was first assembling the printer, but it still looked "good enough." As I was running the calibration tests, it was clear that the bed isn't level. The nozzle hits the bed as it moves towards the back of the bed. But PINDA probe is in the correct position when auto-ed.

The bad thread means that the M3x8r can't screw in through the Y-carriage for that lone corner. I have verified that without the Y-carriage, the screw is able thread in.

Should I remove the receiver and replace it? Is it safe to do so? Or should I wait for a replacement?

Easy solution was to use an m3x12 screw with a washer instead, as the longer thread was able to go deeper into the receiver.
