* USE TYPE I MINIMUM VALUES WHEN YOU MUST ALIGN THE LOCK HOLES (COTTER PINS AND LOCKWIRE)
AT THE ASSEMBLY. USE TYPE II MINIMUM VALUES WHEN IT IS NOT NECESSARY TO ALIGN THE LOCK
HOLES AT THE ASSEMBLY.
** FOR THE SCREWS WITH A THREAD DIMENSION THAT IS LARGER THAN 0.164, AND WITH ONLY A SCREWDRIVER SLOT (NO EXTERNAL WRENCH SHAPE) 22 POUND-INCHES (2.486 NEWTON-METERS) MINIMUM IS PERMITTED.

(2) Thin nuts, nuts with slots, and bolts that are not solid
(a)
The torque limits in the Figure 202 apply to the thin nuts and nuts with slots.
(b)
The height of the nut must be larger than 75 percent of the large diameter of the thread.
(c)
When the nut height is 40 to 75 percent of the large diameter, decrease the torque by 50 percent.
(d)
The height of nuts with slots is measured from the bottom of the nut to the bottom of the slots.
(e)
Values do not apply to bolts and screws that are not solid.
