  2. Distorted thread locknut - Wikipedia

    en.wikipedia.org/wiki/Distorted_thread_locknut

    A distorted thread locknut, [1] is a type of locknut that uses a deformed section of thread to keep the nut from loosening due to vibrations, or rotation of the clamped item. There are four types: elliptical offset nuts, centerlock nuts, toplock nuts and partially depitched (Philidas) nuts.

  3. Locknut - Wikipedia

    en.wikipedia.org/wiki/Locknut

    A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, [1] stiff nut [1] or elastic stop nut, [2] is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. [ 2 ]

  4. List of screw and bolt types - Wikipedia

    en.wikipedia.org/wiki/List_of_screw_and_bolt_types

    A fastener comprising a mated pair of screw and post (binding barrel), which are a machine screw and a nut that is barrel-shaped. The nut has a flange and a protruding boss that is internally threaded. The bolt (mated pair, screw and post) sits within the components being fastened, and the flange provides the bearing surface.

  5. SKF - Wikipedia

    en.wikipedia.org/wiki/SKF

    The startup and growth of SKF depends not only on technical inventions but also on industrial and corporate management strategies and power. Axel Carlander was a co-founder of SKF as a co-owner and member of the board of Gamlestadens Fabriker AB, which corporate policy provided conditions for experimenting with the new bearing models and the startup of SKF, and also he was the first chairman ...

  6. Bolted joint - Wikipedia

    en.wikipedia.org/wiki/Bolted_joint

    Chemical locking methods create friction after the breakaway torque. The prevail torque is usually higher than zero since the cured polymer still creates friction when rotating the nut. [citation needed] Safety wire (lockwire) Holes are drilled in nuts and bolt heads, and wire is threaded through the holes to prevent back-rotation.

  7. Wrench size - Wikipedia

    en.wikipedia.org/wiki/Wrench_size

    spanner (wrench) size and thread diameter of a hex nut. Width across flats is the distance between two parallel surfaces on the head of a screw or bolt, or a nut, mostly for torque transmission by positive locking. The term width across flats (AF) is used for the following forms: 2-socket = round material with two surfaces

  8. Pillow block bearing - Wikipedia

    en.wikipedia.org/wiki/Pillow_block_bearing

    The block is mounted to a foundation, and a shaft is inserted, allowing the inner part of the bearing/shaft to rotate. [1] The inside of the bearing is typically 0.025 millimetres (0.001 in) larger diameter than the shaft to ensure a tight fit. [2] Set screws, locking collars, or set collars are commonly used to secure the shaft. [2]

  9. Split beam nut - Wikipedia

    en.wikipedia.org/wiki/Split_beam_nut

    A split beam nut, also known as a split hex nut [1] or slotted beam nut, [2] is a locknut with slots cut in the top that separate the outside end into two [3] or more sections that are bent slightly inward, making the thread diameter undersized in the slotted portion.
