Torquing involves the process of measuring a force's tendency to produce rotation and torsion about a designated axis. Efficient functioning of a threaded fastener relies upon its objective to clamp parts together with a tension greater than any separating external force. Therefore, the bolt remains under near constant stress, with immunity to fatigue. The necessary tightening torque process is imperative to ensure there is correct initial tension.

Used for reeling and adjusting tension, winches can range from simple mechanical systems to highly sophisticated components. For industrial applications, winches are featured as pneumatic and hydraulic varieties, and are made to be highly enduring and reliable to suit a wide range of operational demands.

Manhattan Island is one of the five New York City Boroughs. Manhattan's utilities, electric, gas, steam, water, sewer, fiberoptic and communication cables are all underground and require specialized equipment to install and service these facilities.
