What is the main advantage of using solid shank rivets in primary aircraft structures?
Easy installation from one side only
High strength and reliability under shear loads
Reusable for multiple assemblies
Designed for temporary joints
The part of the rivet that expands to form a second head during installation is called the:
Mandrel
Shank
Collar
Grip
Which type of bolt is used when alignment of components through a pivot or hinge is required?
Clevis bolt
Eye bolt
Tapered bolt
Shoulder bolt
What is the primary purpose of using washers under bolt heads and nuts in aircraft assemblies?
To prevent corrosion
To provide electrical grounding
To distribute load and prevent surface damage
To ensure proper torque readings
When inspecting a riveted joint, which defect indicates improper installation?
Uniform head shape and diameter
Slightly expanded tail forming a perfect dome
Offset or slanted rivet head
Smooth shank with no deformation
Which of the following materials provides the best corrosion resistance for aircraft bolts?
Carbon steel
Cadmium-plated steel
Titanium alloy
Aluminum alloy
In the bolt designation AN4-15A, the “A” suffix indicates that the bolt:
Is drilled for a cotter pin
Has an undrilled shank
Is made of corrosion-resistant steel
Has a self-locking feature
What tool is primarily used to measure the correct grip length of a rivet before installation?
Micrometer
Rivet gauge
Feeler gauge
Depth micrometer
Locknuts with nylon inserts are generally not used:
On non-structural components
In areas subject to vibration
In high-temperature zones
With aluminum fasteners
Which statement best describes the purpose of torque loading in aircraft bolt installation?
To prevent damage to threads
To stretch the bolt slightly for proper preload
To increase the friction of the washer
To loosen the nut for periodic inspection
