What should I do if the torx flat head screws head is large?

Household appliances used at home have a lot of screws on them for fastening. Generally, the screws on the top are made according to the standard for replacement. When a certain part of the appliance is loosened, it is found that the torx flat head screws is broken and cannot be tightened.

After inquiring about the customer’s use of this screw on the electrical appliance, according to the standard number given by the customer to buy online, the torx flat head screws bought back is found to be larger than the original screw head size. After the screwing, it was found to be very uneven from the surface, and there was a place that was convex. Then find out a grinding wheel to grind the head. After assembly, it is flat from the surface.

Why is this happening? One is the tolerance problem at the time of production. It may be that some of the torx flat head screws are moved according to the upper tolerance and some are taken according to the lower tolerance. Another one is buying fakes.
