RIVETS (AHE)

Question 1

also known as solid rivets; are used widely during assembly and repair work. They are identified by the material of which they are made, the head type, size of shank, length, and temper condition.

Answer 1

SOLID SHANK RIVETS

Question 2

are used under certain conditions when there is access to only one side of the structure. Typically, the locking characteristics of a blind rivet are not as good as a driven rivet.

Answer 2

SPECIAL RIVETS

Question 3

The material used for the majority of solid shank rivets

Answer 3

aluminum alloy

Question 4

Rivets made of US material 1100 are used in the ‘as fabricated’ condition. They are used to attach aluminum alloy components where a low−strength rivet is sufficient to hold the load.

Answer 4

Aluminum Alloy Rivets

Question 5

without heat treatment before use, are used in steel, titanium or aluminum alloy riveted assemblies.

Answer 5

Monel Rivets

Question 6

are rivets with a cylindrical or a partially tapered shank. No heat treatment is necessary for this type of rivet.

Answer 6

Titanium Rivets

Question 7

This is commercially pure aluminum, and a rivet made of this material is too soft and does not have the strength required for structural applications on aircraft. These rivets are designated by the letter A, and there is no identifying mark on their head.

Answer 7

1100 Aluminum (A)

Question 8

these rivets have sufficient strength for structural use. Since they do not need to be heat− treated (as do some of the other types of structural rivets) they can be driven in the condition they are received from the supplier. AD rivets are identified by a small dimple in the centre of their head.

Answer 8

2117 Aluminum Alloy (AD)

Question 9

D−rivets are identified by a raised dot in the centre of their head. They are the most often used rivet in Boeing airplanes. D−rivets are available as standard rivets and as shear head rivets. Shear head rivets have smaller heads than ordinary 100−degree countersink rivets. They are generally used to attach the fuselage skin to the stringers.

Answer 9

2017 Aluminum Alloy (D)

Question 10

DD−rivets are made of heat−treated aluminum alloy and they are so called icebox rivets. They are identified by two raised dashes on their heads. They are placed in cold storage (−10o F or lower) immediately after the heat-treating operation to prevent them from becoming too hard to drive. This type of rivet is used where high strength is required. Icebox rivets must be completely driven within 15 minutes after removal from the freezer or dry ice; they are not to be returned to cold storage once they have been removed.

Answer 10

2024 Aluminum Alloy (DD)

Question 11

Rivets of this material are used for fastening corrosion−resistant steel sheets for such applications as fire−walls and exhaust shrouds. They do not have any marking on their head.

Answer 11

Corrosion−Resistant Steel (F)

Question 12

are identified with two recessed dimples or a raised r in their head and are used in some instances in place of corrosion-resistant steel rivets, where their somewhat lower shear strength is not detrimental.

Answer 12

Monel (M) (Nickel Alloy)

Question 13

also referred as rivet pitch, is the distance between the rivets in the same row,and is measured from the rivet center to the rivet center.

Answer 13

Rivet spacing

Question 14

the distance between the rows of rivets, and is measured from the rivet center to rivet center.

Answer 14

Transverse pitch

Question 15

is the distance from the center of the rivet to the edge of the material being riveted.

Answer 15

Edge distance

Question 16

is the distance from the center of the rivet to the edge of the material being riveted.

Answer 16

Edge distance
