What is generally the best procedure to use when removing a solid shank rivet?
Drill to the base of the manufacturer rivet head with a drill one size smaller than the rivet shank and remove the rivet with a punch
What is the minimum edge distance allowed for aluminum alloy single lap sheet splices containing a single row of rivets as compared to a joint with multiple rows, all rivets being equal in diameter?
Equal to that for the multiple row
Which rivets should be selected to join two sheets of .032" aluminum?
MS20470AD-3-4
The installation of Cherry Max and Olympic-Lok rivets is accomplished by using
a pulling tool
An MS20426AD-6-5 indicates a countersunk rivet which has
an overall length of 5/16"
Threaded rivets (rivnuts) are commonly used to
attach parts or components with screws to sheet metal
The markings on the heat of a Dzus fastener identify the
body diameter, type of head, length of fastener
Allow 2117 rivets are heat treated
by the manufacturer and doe not require heat treatment before being driven
Rivet pitch is the distance between the
centers of adjacent rivets in the same row
Rivet gauge, or transverse pitch is the distance between the
centers of rivets in adjacent rows
A factor which determines the minimum space between rivets is the
diameter of the rivets being used
Most rivets used in aircraft construction have
dimples
A rivet set used to drive MS20470 rivets should
have a slightly greater radius than the rivet head
The Dzus turnlock fastener consists of a stud, grommet, and receptacle. The stud length is measured in
hundredths of an inch
Under certain condition, type A rivets are not used because of their
low strength characteristics
Which rivet is used for riveting nickel-steel alloys
monel
Heat treated rivets in the D and DD series that are not driven within the prescribed time after heat treatment or removal from refrigeration
must be treated before use
A main difference between lock bolt/huck bolt tension and shear fasteners (other than their application) is the
number of locking collar grooves
When an MS20470 rivet is installed, its full shear strength is obtained
only after a period of age hardening
Hole filling fasteners (for example, MS20470 rivets) should not be used in composite structures primarily because of the
possibility of causing delamination
Which of the following need not to be considered when determining minimum rivet spacing
rivet length
What type of loads cause the most rivet failures
shear
A well designed rivet joint will subject the rivets to
shear loads
The Dzus turnlock fastener consists of a stud, grommet, and receptacle. The stud diameter is measured in
sixteenths of an inch
A DD rivet is heat treated before use to
soften to facilitate riveting
The identifying marks on the heads of aluminum alloy rivets indicate the
specific alloy used in the manufacture of the rivets
Mild steel rivets are used for riveting
steel parts
One of the main advantages of Hi-Lok type fasteners over earlier generations is that
they can be installed with ordinary hand tools
What is one of the determining factors which permits machine countersinking when flush riveting
thickness of the material is greater than the thickness of the rivet head
What is the minimum spacing (pitch) for a single row of aircraft rivets?
three times the diameter of the rivet shank
What is the purpose of refrigerating 2017 and 2024 aluminum alloy rivets after heat treatment
to retard age hardening
What is the minimum edge distance for aircraft rivets?
two times the diameter of the rivet shank
The width of the shop head of a rivet should be
1.5 times the diameter of the rivet shank
The length of a rivet to be used to join a sheet of .032 inch and .064inch aluminum allow should be equal to
1.5 times the rivet diameter plus .096"
A sheet metal repair is to be made using two pieces of 0.04 inch aluminum riveted together. All rivet holes are drilled for 3/32" rivets. The length of the rivets to be used will be
1/4"
The dimensions of an MS20430AD-4-8 rivet are
1/8" in diameter and 1/2" long
The primary allowing agent of 2024-T3 is indicated by the number
2
Which rivet may be used as received without further treatment
2117-T3
The general rule for finding the proper rivet diameter is
3 times the thickness of the thickest sheet
The length of a rivet to be chosen when making a structural repair that involves the joining of 0.032" and 0.064" aluminum sheet, drilled with a No. 30 drill is
5/16
A sheet metal repair is to be made using two pieces of a 0.0625" aluminum riveted together. All rivet holes are drilled for 1/8 in rivets. The length of the rivets used will be
5/16"
which rivet is used for riveting magnesium alloy structures
5056 aluminum
