1. Working mode and convenience
The ordinary wrench is used to tighten the fastener manually. It is necessary to select a suitable opening size, and the wrench must be picked up from the fastener when screwing, so the adjustment speed is slow. The ratchet wrench is equipped with a one-way engagement device, which can quickly rotate back and forth without picking up the wrench. It is fast and convenient without breaking away from the fastener.
2. Different degrees of protection for bolts and nuts
Because the ordinary wrench is adjusted manually, the error is large, and the corners of the nut are easy to be worn; The ratchet ratcheting wrench has the ability to strictly bite the nut, which can protect the nut edges from being rounded.
