Rivet Exam block 5
Rivet gauge or transverse pitch is the distance between the
Center of the rivets in adjacent rows
Rivet pitch is the distance between the
Centers of adjacent rivets in the same row
A factor which determines the minimum space between rivets is the
Diameter of the rivets being used
What is generally the best procedure to use when removing a solid shank rivet?
Drill to the base of the manufactured rivet head with a drill one size smaller than the rivet shank and remove the rivet with a punch
Which rivets should be selected to join two sheets of .032" aluminum
MS20370AD-4-4
When riveting dissimilar metals together, what precautions must be taken to prevent an electrolytic action?
Place a protective separator between areas of potential electrical difference.
Which of the following need not be considered when determining minimum rivet spacing?
Rivet length
What types of loads cause the most rivet failures?
Shear
Joggles I'm removed rivet shanks would indicate partial
Shear failure
The identifying marks on the head of aluminum alloy rivets indicate the
Specific alloy used in the manufacture of the rivets
The dimensions of an MS20430AD-4-8 rivet are
1/8 inch in diameter and 1/2 inch long.
Single lap sheet splice is to be used to repair a section of damaged aluminum skin. If a double row of 1/8" rivets is used, the minimum allowable overlap will be
13/16"
Which rivet may be used as received without further treatment?
2117-T3
Which is the grip length of the flush rivet
3 (middle one)
A sheet metal repair is to be made using two pieces of 0.0625" aluminum riveted together. All rivet holes are drilled for 1/8" rivets. The length of the rivets to be used will be
5/16"
The length of 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"
Which rivet is used for riveting magnesium alloy structures?
5056 aluminum
How many MS20470 AD-4-6 rivets required to attach 10"x5" plate using a single row of rivets, minimum edge distance and 4D spacing?
56
What is the minimum edge distance allowed or aluminum alloy single lap sheet splices containing a single rivets being equal in diameter?
The minimum edge distance for the single row is equal to that for the multiple row
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 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
MS20426AD-6-5 indicates a countersunk rivet which has
an overall length of 5/16 inch
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.
Under certain conditions, type A rivets are not used because of their
low strength characteristics
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 reheat treated before use.
The length of a rivet to be used to join a sheet of .032-inch and .064-inch aluminum alloy should be equal to
one and one-half times the rivet diameter plus .096 inch.
When an MS20470D rivet is installed, its full shear strength is obtained
only after a period of age hardening
Aircraft structural units, such as spars, engine supports, etc., which have been built up from sheet metal, are normally
repairable, using approved methods
Mild steel rivets are used for riveting
steel parts
Which rivet is used for riveting nickel-steel alloys?
Monel
