3. Job Set-up
Subtask 20-21-11-911-058-A
A. Standard Threaded Fasteners - General
   (1) The threaded fasteners are identified with a standard number written on the head (example: ABS, AN, ASNA, NAS, ASN, NSA, MS). They are installed in standard conditions and lubricated.
   (2) Before you apply a tightening torque to a fastener, make sure that you know its correct part number.
To find the correct part number of a fastener (screw, washer, nut), refer to the installation figure of the IPC.
NOTE: It is necessary to know the fastener standard and diameter to know the correct tightening torque.
   (3) The tightening torques of the TAPERLOK, HI-LOK, and HI-LITE screws are specified in the given procedures SRM 514900.
   (4) The torque values of the nuts and the screws are given with their initial lubricants.
   (5) These torque values are available for the different screw/nut diameters:
  • The minimum value
  • The nominal value
  • The maximum value.
   (6) Make sure that you get the correct part mating before you apply the maximum torque value.
Subtask 20-21-11-911-059-A
B. Used Fasteners:
   (1) General
Before you use a threaded fastener again, make sure that:
  • There is no deterioration of the thread of the screw and of the nut, of the mating surface of the nut and of the recess of the screw.
  • The protection of the screw and of the nut is not damaged.
NOTE: If the protection is damaged, corrosion or seizure can occur.
  • The condition of the standard lubricant is correct. Apply a new layer of standard lubricant if necessary.
NOTE: Deterioration of the lubricant decreases the preload values and can:
  • Cause damage to the mating surfaces
  • Decrease the torque for self-locking nuts.

  • The screws and nuts are serviceable (get approval from your quality department or a qualified mechanic).
   (2) Do not use aluminum, titanium and Inconel nuts again.
   (3) Do not use self-sealing nuts again.
   (4) Self-locking nut (this includes castellated nuts with a nylon ring)
  • Airbus does not recommend that you can use a self-locking nut again,
  • If you use a self-locking nut again, make sure that the breakaway torque value is more than the minimum breakaway-torque value.
NOTE: Refer to the nut standard to know the minimum breakaway-torque value.
NOTE: To measure the breakaway torque value, the screw end must come out of the nut.
   (5) Limits for captive nuts
     (a) When you install a screw in a captive nut, make sure that you feel the breakaway torque resistance of the nut.
NOTE: After some screw removal/installation cycles, the breakaway torque value of the captive nut can decrease and cause the screw to become loose or missing.
       1 If you think that the resistance is not sufficient, Airbus recommends that you replace the nut.
       2 If you are not sure that the resistance is sufficient:
  • Refer to the captive nut standard to know the minimum breakaway torque value.
NOTE: If there is no minimum breakaway torque value in the standard, refer to the procurement specification applicable to the captive nut.
  • Make sure that the breakaway torque value is equal to or more than the specified value.
       3 Replace the captive nut if necessary.
Subtask 20-21-11-911-064-A
C. Fasteners Installed on Uncured Interfay Sealant
   (1) General
When the fasteners (for example, screws/nuts or TAPER-LOK fasteners) are installed on uncured interfay sealant, their preload can decrease after curing because the sealant does not flow immediately.
This is why it is necessary to tighten them again. Do this 30 minutes after installation of the fasteners.
If there are more than two parts assembled together, tighten again at 30-minute intervals until the torque value stays correct.
Subtask 20-21-11-911-060-A
D. Tightening - Tools:
   (1) General
     (a) Before you use a tightening tool, make sure that the calibration of this tool is correct.
     (b) Make sure that the torque is applied correctly.
You can apply unwanted torsion or flexion to the component if:
  • The position of the wrench (or the screwdriver) is incorrect.
  • You apply the tightening torque incorrectly: this can change the tightening torque and thus the preload.
   (2) Torque wrench
     (a) Torque wrench range
For a given torque value, we recommend that you use a torque wrench that has a value in the range of 30% to 80% of the full range.
NOTE: Example for a torque wrench of maximum 10 m.daN:
  • Torque wrench range from 2 m.daN to 10 m.daN
  • Recommended range 3 m.daN to 8 m.daN.
In the recommended range:
  • only moderate force is necessary to get the correct torque,
  • you can feel the force increase while you apply the torque.
     (b) Torque wrench hold
The torque wrench axes must be perpendicular to the fastener axis.
Put your hand on the handle and pull it along the axis.
Apply the torque value gradually and perpendicularly to the wrench.
Stop the movement when the wrench releases (or on the signal).
Do not use a torque wrench to loosen a fastener.
   (3) Torque wrench adapter
     (a) When you use an adapter:
F Torque Wrench and Adapter Combination
  • The value shown on the dial of the torque wrench is not the applied value.
  • Make sure that the length of the torque wrench is more than the length of the adapter.
NOTE: Airbus recommends to have the torque wrench and the adapter aligned.
If you cannot align the torque wrench and the adapter (because of the fastener location), you can use the torque wrench and the adapter not aligned.
     (b) Torque-value correction applicable when the adapter is used:
NOTE: This procedure is applicable when the adapter and the torque wrench are aligned or not aligned
F Torque Wrench and Adapter Combination
       1 To pre-calibrate the torque wrench, you can use this formula to get the torque-wrench dial-reading:
T1 x A
T2 = --------
A + B
T1: Value that you must apply on the fastener
A : Length of the torque wrench
B : Length of the adapter
T2: Torque-wrench dial-reading.

       2 Calibrate the torque wrench and the adapter assembly on the torque meter.
  • Adjust the T2 value until you get the T1 value on the torque meter.
  • Do the tightening operations five times, one after the other to make sure that the torque wrench and the adapter are calibrated correctly.
       3 Tighten the fastener to the corrected value.
   (4) Screwing machine:
When you use a screwing machine, make sure that the speed is correct to prevent too much heat on the fasteners.
NOTE: This can cause damage to the protection and the lubricant and can cause seizing of the fastener.
4. Procedure
Subtask 20-21-11-911-061-A
A. General
   (1) Tightening for fasteners without a captive nut
     (a) Install the nut manually to make sure that a minimum of one thread is engaged.
     (b) In relation to the nut and screw standards and diameter, get the correct torque value.
     (c) Apply the torque value on the nut:
  • If you cannot tighten with the nut, apply the screw torque value.
  • It is recommended to apply the nominal torque value.
  • Do not apply more than the maximum torque value.
     (d) Castellated nuts
       1 If the torque value tolerance does not let you put a slot opposite a hole for a cotter pin, you can do this in the sequence that follows (successively):
  • Decrease the minimum torque by 10%
  • Install a washer below the nut
  • Replace the nut.
       2 You can drill the hole during installation. If you do this:
  • Make sure that you do not decrease the strength of the screw (specially for offset drilling, the diameter of the bore must be correct, deburr lightly).
  • You must prevent corrosion (put grease in the hole of the nut when you install steel bolts).
NOTE: It is recommended to use screws with their initial drill holes.
     (e) Shoulder screws
       1 Tighten with the nut.
The minimum torque you must apply is to between .2 and .1 m.daN (17.70 and 8.85 lbf.in ) T.
       2 If you install a castellated nut, the tightening torque tolerance does not always let you align the castellated nut with the hole for the cotter pin. If you cannot align the castellated nut with the hole for the cotter pin, install a steel teflon washer NSA5325 .
       3 For maximum torque values
F Maximum Torque Values for Shoulder Bolts
   (2) Tightening for fasteners with captive nut
     (a) Make sure that the length of the screw is correct.
     (b) Install the screw manually to make sure that a minimum of one thread is engaged.
     (c) In relation to the nut and screw standards and diameter, get the correct torque value.
     (d) Apply the tightening torque on the screw.
Subtask 20-21-11-910-050-A
B. Nut or Screw Assembly Table Instruction
   (1) Get the nut and screw standards and diameter.
   (2) Find the correct nut/screw assembly table.
The nut and the screw standards are given with a space between the reference standard and the last letter.
   (3) The illustrations above the related paragraph tables give the torque value for the nut/screw assembly, for each diameter.
NOTE: To find the screw or nut standard easily in the table, you can use the Airnav "SEARCH" function as follows:
  • Enter the screw and/or nut standard (with a space as separation) in the "Full text search" line of the Airnav "Word Search" tool. If there is a letter at the end of the standard, you can replace it with the star (*) character.
  • Start the search and find the screw or nut standard in the table.
  • If the search shows no result, you can replace the last one or two digit(s) of the standard with the star (*) character and start the search again.
   (4) Refer to the correct table that gives the screw-and-nut assembly. Then, refer to the related illustration to get the related torque value.
