what is the difference between a flare nut wrench and a standard box wrench

by Prof. Rory Grady Published 2 years ago Updated 2 years ago

Both the flare-nut wrench and regular wrench are going to have a head and handle. Generally, regular wrenches have longer handles than flare-nut models, but that can depend on the exact model. As for the head, a flare-nut wrench is 5-sided. A regular wrench, on the other hand, will have a 2-sided head that looks like a U.

Flare-nut wrenches tend to have more gripping power. Since the models are more fitted, they can more snugly grip small nuts and other fitted hoses. The U-shaped design of regular wrenches, on the other hand, means they don't fit or grip as tightly as flare-nut wrenches.Jul 18, 2022
