Gearwrench 90-Tooth Ratchets with Standard and Flex Heads:
The Gear Wrench 90-Tooth Ratchets are used to tighten or loosen nuts, bolts, washers, screws and other fasteners. They have a standard size of 1/2″ x 3/4″. These ratcheting tools come in different sizes so that they can be used to tighten or loosen various types of fasteners.
There are two main types of ratcheting tools; those with standard and those with flexible heads.
Standard Ratchets – These ratchets have a fixed jaw and a sliding jaw which allows them to fit into tight spaces such as inside the jaws of a nut, bolt or screw. The teeth are usually made from hardened steel and there is one side that fits into the slot in the head of the fastener while another side slides over it.
Flexible Ratchets – These ratchets have a sliding jaw which allows them to fit into tight spaces such as inside the jaws of a nut, bolt or screw. The teeth are usually made from softer metals like plastic and there is one side that fits into the slot in the head of the fastener while another side slides over it. Some flexible ratchets have a small ball at their end to make sure they don’t slip out when tightening or loosening fasteners.
In addition to the above, there are other features that you can find when you buy ratcheting tools. You can find a ratchet with a built-in magnet that makes it easier to work on older cars or motorcycles. There are also different types of handles such as standard or pistol grip.
On some ratchets, you can switch between the normal and an extended reach position for more flexibility. You can also find ratchets that have a quick release option to help you in fastening or unfastening quickly.
The gearwrench 90-tooth ratchets set is available in different sizes, and the size you should buy will depend on the size of nuts, bolts or other fasteners that you need to work with. The most common ratchet sets come in seven-piece and twelve-piece sizes.
