Screw sizes are written in an alphanumeric code that can be difficult to decipher if you're not familiar with the system. Sequences like "4-30 x .10," "1/8-10 x 4/6" and "M5-.4 x 15" may seem meaningless, but they say a lot, and you need the right screw to do the job....
Tip:If the half mm increment is showing on the primary scale, add 0.5mm to the total reading. There are a variety of micrometers in the market from simple ones like theMitutoyoon above to ones with a digital readout and many sizes both in inch and metric. Be sure to check outMISUMI...
Measuring tape reading might seem like a no-brainer at first glance, but all those marks, symbols, and fractions can make your head spin when you try to use one in a pinch – just ask me. I grew up in the metric system, so any measurement under a 1/4″ has me cross-eyed and co...

Calibrate the micrometer you will use to measure the bearing. Open the micrometer and fit the gauge block between the measuring tips. Turn the thimble to close the micrometer until the measuring tips contact the block. Read the measurement to ensure a margin of error that is no more than ...

The tool is as universally important as the hammer and the wheel. Here’s how to pick (and use) the right one.

the designated pitch and shape of the thread, and designated diameter sizes. In 1966, the International Standards Organization (ISO) suggested a universal restriction on threads to ISO metric and inch size ranges with coarse and fine pitches. Compliance with the ISO suggested standards has been glo...
Another useful metric for gauging efficiency is “grams per amp” (thrust/current). Generally, as thrust increases, so does the current required to produce it. Therefore, motors with high thrust and low current draw are preferable. Inefficient motors may generate insufficient thrust or draw excessi...
