Tips: Basics of a ratchet
The ratchet is a special hand tool for tightening or loosening screws. The ratchets are generally equipped by a set of sockets of various specifications, as well as flexible rod, extension bar, universal joints, socket bits, etc.
Generally, the models and specifications of ratchet are distinguished by the size of the square drive, the length of the ratchet and the number of internal teeth of the ratchet.
The square drive sizes of ratchet: 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch. As we know, 1 inch equals 25.4mm. According to the metric system, they are 6.3mm, 10mm, 12.5mm, 19mm. When choosing the ratchet, it should firstly consider the drive size of the ratchet. For example, if the ratchet square head is 3/8 inch, a 3/8 inch drive socket should be chosen, and then a suitable socket will be selected according to the specifications of your bolts.
The length of the ratchet also affects the use of the rathet. Of course, the ratchet with a longer arm can provide extra leverage.
For the teeth of ratchet, there are 24 teeth, 36 teeth, 45 teeth, 72 teeth and so on. The number of gears is different, and the rotation angle of each tooth is different. The smaller the number of teeth, the larger the force-bearing area, the larger the area of engagement between the teeth and the clip, and the better its bearing capacity. With more teeth, the angle is more flexible and adapts to tight spaces.
