Box end wrenches are used for turning hard-to-reach nuts and are therefore useful for fine indexing with better speed and access. A box wrench completely surrounds the nut and bolt and is less likely to slip. It also avoids rounding off at the edges. Box wrenches are designed to fit square and hexagonal shaped nuts and bolts and come in different lengths and sizes for ease of access. These products come in both SAE and metric 6- and 12-point variants and are made of alloy steel, aluminium bronze, chrome vanadium steel or nickel aluminium bronze. Raptor Supplies offers a wide range of Wright Tool, Proto, Facom, Westward, Ampco, SK Professional Tools and Knipex wrenches in different sizes.
