For many customers who need to buy a screw caster wheel, how to determine the diameter of the screw is a headache. Because there are several screw diameters for screw wheels of the same specification, the commonly used screw sizes are M8, M10, and M12, and some customers do not have professional measuring tools or even rulers for stationery.
Today, I will share with you the method of confirming the size of the screw caster wheel with the 1 yuan people's banknotes. First of all, we took out a 1 yuan people's banknote, as shown below:
Then we put the screw up and compared with the numbers in the lower left corner. Note that there is no "1" among the numbers to be compared, because if there is a number "1", it will cause an error in the comparison result.
First, the screw can't cover 3 numbers, it is the M8 screw caster wheel, as shown below:
Second, the screw can completely cover the 3 digits, which is the M10 screw caster wheel, as shown below:
Third, the screw can completely cover 4 digits, it is the M12 screw caster wheel.
