Impact Wrenches are used for fastening nuts and bolts. Impact wrenches are known for their super - fast speed which allows the user to get jobs done faster. Cordless impact wrenches are light-weight, easy to operate and offer better manoeuvrability. Rechargeable batteries are used to power cordless impact wrenches. These wrenches have an inbuilt LED light to enhance visibility for the user in lower light conditions. Shear wrenches come with anti-slipping mechanism.
