Rivets & Riveting
A well-designed rivet joint will subject the rivets to
Shear loads
The identifying marks on the heads of aluminum alloy rivets indicate the
Specific alloy used in the manufacture of the rivet
T/F best to match alloy parts if possible
True
MS20426AD-6-5 indicates a countersunk rivet which has
an overall length of 5/16
Alloy 2117 rivets are heat treated
by the manufacturer and do not require heat treatment before being driven.
Rivet gauge, or transverse pitch is the distance between the
center of 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
Most rivets used in aircraft construction have
dimples
Under certain condition, 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 re-heat treated before use
The shop head of a rivet should be...
one and one-half times the diameter of the rivet shank.
When an MS20470D rivet is installed, its full shear strength is obtained
only after a period of age hardening
A DD rivet is heat treated before use to
soften to facilitate riveting
Mild steel rivets are used for riveting...
steel parts
What is the purpose of refrigerating 2017 and 2024 aluminum alloy...
to retard age hardening
Bucktail should be
1 1/2 shank diameter
The dimensions of an MS20430AD-4-8 rivet are
1/8 inch in diameter and 1/2 inch long.
What is the minimum edge distance for aircraft rivets
2 times the diameter of the rivet shank
Which rivet may be used as received without further treatment?
2117-T3
What is the minimum spacing for a single row of aircraft rivets
3 times the diameter of the rivet shank
The general rule for finding the proper rivet diameter is
3 times the thickness of the thickest sheet
