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
