Measurement Methods
Ways to Avoid Buying the Wrong Screws
Measure with a standard vernier caliper.
Screws are standard parts. The plus-minus tolerance can be accurate to 0.01 millimeter.
Don’t use tape measures, straight rulers or student rulers for measurement, as this is the most error-prone way. The error range of plus-minus tolerance is 1 to 2 millimeters.
