Tubular wrenches, also known as box-end wrenches or ring wrenches, are used for tightening or loosening bolts and nuts in various applications. They are characterized by a closed-end, ring-shaped jaw that fits snugly around the bolt or nut, providing a firm grip without slipping off the fastener. Tubular wrenches typically come in sets with different sizes to accommodate different bolt or nut sizes.

Tubular wrenches are commonly used in mechanical, automotive, and industrial settings, as well as in DIY projects. They are especially useful in tight spaces where a standard open-end wrench or a socket wrench may not fit properly. The closed-end design of tubular wrenches also helps to distribute force more evenly on the fastener, reducing the risk of rounding or damaging the edges of the bolt or nut.

Tubular wrenches are available in various configurations, including single-ended, double-ended, and offset designs, to suit different types of fasteners and applications. Some tubular wrenches may also have additional features, such as ratcheting mechanisms, to facilitate faster and more efficient tightening or loosening of bolts and nuts. It's important to select the appropriate size and type of tubular wrench for the specific task at hand to ensure proper fit and optimal performance.
