RAK toilet seat coming loose

[Aliplumbingonabudget]

I have a RAK toilet and seat, the seat keeps coming loose on one side, I tighten the screw but it doesn't last long. My question is will a replacement screw cure the problem or will I need to get a new seat?

There’s not enough information here, but if it’s a top fix seat it is more likely to be the “plug” that the screw tightens into which needs replacing

Is it the type with 2 grub screws that wind in horizontally?
