Fig.
1 For checking threads
-
Find a hole with a similar size to the object
(a bolt, stud or
screw to be checked) (Fig 1).
- Connect the object to the hole to see if the hole matches the
object.
- Note: When the
object threads match holesˇ¦ threads, the object can be
rotated smoothly. If any un-smoothness occurs, it is an
indication that the threads do not match. Connection with force
may cause holesˇ¦ threads damaged.
Fig
2: For checking diameter
- Position the object against the innermost part of the
V-shape
groove.
- Find the point
where the edges of the object and the gauge touch each other
(see the arrows on Fig 2), and read the marking.
Fig
3: For checking length
- Place the object on both sides of the
gauge
(SAE on the right and metrics on the left).
- One end of the object should align the
upper line
of the gauge (Fig. 3 and 4) and read the marking.
