✔✔How many minutes are in a degree? - ✔✔60 minutes
✔✔What is a vernier scale? - ✔✔Compares 2 sets of graduations to magnify the
accuracy of the measuerment
✔✔What does a dial caliper use to move its pointer around the face of a dial - ✔✔Rack
and pinion
✔✔What is the construction of a micrometer? - ✔✔1. Anvil
2. Spindle
3. Sleeve
4. Thimble
5. Ratchet
6. Lock nut
7. Frame
✔✔What method provides most accurate measurement when it comes to a
micrometer? - ✔✔Ratchet method because it releases at the same pressure every time
✔✔Regular micrometer scale level of accuracy is: - ✔✔0.001"
✔✔Vernier micrometer scale level of accuracy is: - ✔✔0.0001"
✔✔What is an Intrimik? - ✔✔Has 3 contact points rather than 2 making it self centering
✔✔What is different about the scale of a depth micrometer from a regular micrometer? -
✔✔The distance measured is covered by the thimble
✔✔What kind of tool is a taper gauge? - ✔✔Direct reading tool
✔✔What is a taper gauge used for ? - ✔✔Determining the width of a slot or diameter of
a hole and amount of angular misalignment
✔✔The difference between a screw and a bolt is the: - ✔✔Application
✔✔Why are thread forming screws used? - ✔✔Convenient in sheet metal assemblies
✔✔The major diameter of a thread is shown on a drawing as 0.748 +/- 0.002. What is
the tolerance on the major diameter? - ✔✔0.004
, ✔✔The pitch diameter of a thread is measured exactly halfway between the major and
minor diameters - ✔✔False. Its APPROXIMATELY halfway between the major and
minor diameter
✔✔On a general purpose ISO metric thread, what character in the designation indicates
a medium tolerance grade? - ✔✔Grade 6
✔✔An ISO metric thread is designated by M14 x 2 - 6g. What is the pitch of this thread?
- ✔✔2MM
✔✔What are 2 types of tapered thread form? - ✔✔NPT and NPTF
✔✔The unified thread class that offers the tightest fit is: - ✔✔3
✔✔The designation that identifies a nut is: - ✔✔B
✔✔Marks on the head of a bolt indicate the: - ✔✔grade and tensile strength
✔✔A thread is designated 5/8 - 11 Class 2A. The thread shown: - ✔✔is an external
thread
✔✔The thread angle from an American National Acme Thread is: - ✔✔29 degress
✔✔A no go ring gauge is easliy identified by: - ✔✔annular ring on the knurled surface
✔✔Thread comparison gauges use __________ as a basis for thread size - ✔✔Pitch
diameter
✔✔Rolled threads are advantageous over machined threads because: - ✔✔They have
increased tensile strength
They produce a burnished thread finish
They have better wear resistance which reduces fatigue and shear problems
✔✔What does API stand for - ✔✔American Petroleum Institue
✔✔What kind of threads do Acme threads have? - ✔✔29 degree angle and the root and
crests are flat
✔✔Hex set screws may sometimes be doubled up - ✔✔True
✔✔What are cap screws made of? - ✔✔High tensile steel
