2. Micrometer adjustment nut - Wikipedia

   en.wikipedia.org/wiki/Micrometer_adjustment_nut

   The nut is located on a threaded rod on the mill head. The machine operator moves it up or down by rotating it clockwise (to move it down) or counter-clockwise (to move it up). Moving the nut down increases the depth to which the cutting tool may plunge into the workpiece. Moving the nut up reduces the depth to which the cutting tool may plunge ...

3. Micrometer (device) - Wikipedia

   en.wikipedia.org/wiki/Micrometer_(device)

   Lock nut, lock-ring, or thimble lock: The knurled component (or lever) that one can tighten to hold the spindle stationary, such as when momentarily holding a measurement. Thimble: The component that one's thumb turns. Screw: (Not visible) The heart of the micrometer, as explained under "Operating principles". It is inside the barrel.

4. 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 ]

5. Differential screw - Wikipedia

   en.wikipedia.org/wiki/Differential_screw

   Many differential screw configurations are possible. The micrometer adjuster pictured uses a nut sleeve with different inner and outer thread pitches to connect a screw on the adjusting rod end with threads inside the main barrel; as the thimble rotates the nut sleeve, the rod and barrel move relative to each other based on the differential between the threads.

6. Positive locking device - Wikipedia

   en.wikipedia.org/wiki/Positive_locking_device

   A positive locking device is a device used in conjunction with a fastener in order to positively lock the fastener. This means that the fastener cannot work loose from vibrations. The following is a list of positive locking devices: [1] A split beam nut; A castellated nut and a split pin; A hex nut or cap screw and a tab washer

7. Jam nut - Wikipedia

   en.wikipedia.org/wiki/Jam_nut

   Standard nut employed as a jam nut against another standard nut. A jam nut is a low profile type of nut, typically half as tall as a standard nut. It is commonly used as a type of locknut, where it is "jammed" up against a standard nut to lock the two in place. It is also used in situations where a standard nut would not fit.

8. Micrometer - Wikipedia

   en.wikipedia.org/wiki/Micrometer

   Micrometer can mean: Micrometer (device), used for accurate measurements by means of a calibrated screw; Micrometre, a millionth of a metre

9. Micrometre - Wikipedia

   en.wikipedia.org/wiki/Micrometre

   The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10 −6 metre (SI standard prefix "micro-" = 10 −6); that is, one millionth of a metre (or one thousandth of a ...
