  2. Bolted joint - Wikipedia

    en.wikipedia.org/wiki/Bolted_joint

    The applied torque causes the bolt to "climb" the thread causing a tensioning of the bolt and an equivalent compression in the components being fastened by the bolt. The preload developed in a bolt is due to the applied torque and is a function of the bolt diameter, the geometry of the threads, and the coefficients of friction that exist in the ...

  3. Torque-to-yield fastener - Wikipedia

    en.wikipedia.org/wiki/Torque-to-yield_fastener

    The torque applied to the fastener must be determined such that it does not contribute to a service condition where the fastener enters a low-cycle fatigue regime. In general, the use of torque-to-yield fasteners is deprecated except in cases where the materials and structures comprising the entire assembly are certified to be within tolerances ...

  4. Preload control - Wikipedia

    en.wikipedia.org/wiki/Preload_control

    Preload control. Amount of the no-load tension in the bolted joint (preload) greatly affects the reliability of the joint. Multiple techniques exist for preload control to ensure that the tension in the bolt is close to the one specified in the design (some bolt-to-bolt statistical variations are inevitable): [1] torque-controlled tightening is ...

  5. Torque wrench - Wikipedia

    en.wikipedia.org/wiki/Torque_wrench

    A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...

  6. Direct tension indicator - Wikipedia

    en.wikipedia.org/wiki/Direct_tension_indicator

    Functioning. DTIs are a function of induced tension. As a fastener assembly is tightened, the arch-like protrusions are compressed, and the change in distance between the base of the protrusions of the DTI washer and the protrusion apex correlates to a value of tensile force induced into the fastener. This distance can be verified by insertion ...

  7. Torque - Wikipedia

    en.wikipedia.org/wiki/Torque

    t. e. In physics and mechanics, torque is the rotational analogue of linear force. [1] It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.

  8. Pound-foot (torque) - Wikipedia

    en.wikipedia.org/wiki/Pound-foot_(torque)

    Gravitational metric system. ≈ 0.1382550 kgf⋅m. A pound-foot (lb⋅ft), abbreviated from pound-force foot (lbf · ft), is a unit of torque representing one pound of force acting at a perpendicular distance of one foot from a pivot point. [2] Conversely one foot pound-force (ft · lbf) is the moment about an axis that applies one pound-force ...

  9. Screw thread - Wikipedia

    en.wikipedia.org/wiki/Screw_thread

    A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a threaded fastener. The mechanical advantage of a screw thread depends on its lead, which ...
