To prevent bottoming of the nut—ANSWER Why should the grip length of a bolt
be a few thousandths of an inch shorter than the material?
thickness?
Overall length, including grip length and threaded components - What
considerations do you consider when determining the length of a bolt?
(1) Bolt head markings.
(2) Part number designation - ANSWER: What are the two ways to identify bolts?
TO 1-1A-8 - ANSWER Where do you look if you can't recognize the code on the
head of a bolt?
The type of bolt, its diameter, length, grip length, and whether the head or shank is
drilled. - ANSWER: What information does the component number identification
provide about a bolt?
The bolt will be unable to carry its shear stress, causing the item to distort.
ANSWER: Why must bolt holes not be large or elongated?
If the larger hole does not weaken the component. - ANSWER: When may you
drill or ream a hole to accommodate an enlarged diameter or a larger bolt?
Torque all nuts to the right specifications - ANSWER How can you avoid stripping

(3) The maximum temperature for CRES nuts is 800 degrees Fahrenheit. -
ANSWER: What temperature limits should you consider when installing nuts?
,How can you prevent fatigue failure in bolted assemblies? By properly tightening
the bolt and delivering suitable preload or clamping force.
By adhering to the right torque parameters - How can you limit the tendency of
parts to creep or shift when installing bolts?
Thread roughness, painting, lubrication (oil, grease), hardness, and plating. -
ANSWER: What factors can affect standard torque chart values?
What are the three major components of a camloc fastener?
Disassemble it. - ANSWER: What should you never do with a camloc stud?
How can you determine the grip length of a camloc stud based on the number
inscribed on its head?
A floating receptacle - What should you use to replace a stiff receptacle?
What should you do after punching the grommet hole? Deburr and sand the edges
smooth.
When the stud is put in the grommet, do you attach a stud retaining ring?
Check the grip length of the stud - What is the final step in Camloc installation?
, ANSWER: What are the three primary pieces of an airlock fastener?
ANSWER: How can you determine the grip length of an airloc stud?
Refer to TO 1-1A-8 and the aircraft-specific TO - How do you calculate the
necessary stud lengths for floating and rigid receptacles?
The final step in airlock installation is to check alignment and fasten the airloc stud.
(1) Fastening the studs in a different sequence.
(2) Install a longer stud (0.010 to 0.020 inch longer).
(3) make the stud hole slightly larger.
(4) Replace the rigid receptacle with a floating kind.
