what are the two classes of rivets
solid and hollow rivets
what is the most common way of identifying a hollow rivet
identification details is labeled on the packaging.
are the material and specification of American and British rivets the same
if you want to make a change to a rivet specification you must seek a permission form whom
aircraft manufacturer
wrt location, what is a pitch
horizontal distance between two rivets (centre to centre) it should at least 4 times the diameter of the rivet (4D)

wrt rivet location, what is spacing

vertical distance between two rivets, it must be at least 3D or 4D
wrt location, what is a land
distance (horizontal or vertical) between rivet and the adjacent edge, it should be no less than 2D
what is a rivet allowance
the amount of shank that protrudes from the hole, it should be 1.5D (for normal tail) and 0.5D (for countersunk tail)
what is rivet clearance
the internal clearance between the rivet shank and the hole, should be about 0.1mm
one of the surfaces that are in contact at a joint is called?

what can you read from the following part


ms = military starndard

20 = catalogue number

470 = universal head

AD = aluminium alloy (field rivet)

4 = 4/32" diameter

-4 = 4/16" length

what can you read from the following part


ms = military starndard

20 = catalogue number

476 = countersunk head

DD = icebox rivet

4 = 4/32" diameter

-4 (dash 4) = 4/16" length

name two of the most jointed compounds used
PRC and zinc chromate
the type of rivet joint is dictated by what

the location of the riveting

i.e. laminar boundary layer area should have a single strap butt joint

name four different rivet joints

lap joint

single strap butt joint

double strap but joint

joggled lap joint

what type of joint is used where aerodynamic finish and strength is essential

single strap butt joint
what type of rivet joint would you use if an aerodynamic finish is necessary but strength could be less than that of single strap butt joint
jogled lap joint (faying may be filled with jointing compound)
what type of rivet joint Is used where a strength alone is essential (no aerodynamic finish required)
double strap butt joint
what should the rivet diameter be wrt to the thickness of a single sheet of the material that is being joined

three times the thickness of a single sheet that is being joined

state a three items that would make a complete tool which could then be used to close a rivet

rivet snap ( correct shape for the rivet head)

reaction block AKA dolly

pneumatic hammer (rivet gun plier)

describe the process that may be used to close a solid rivet
put the rivet in the hole. while holding a dolly at the tail, apply pneumatic hammer at the head
describe how to close a hollow rivet using lazy tong plier
insert the rivet in to the chuck and then to the hole and pressure down the handle
where a bit more strength is needed an avdel rivet Is used, how does and avdel rivet provide more strength than that of a head break tucker pop rivet
because the mandrel is left in the rivet, the mandrel in the rivet provides some strength
cherry max rivet consist of four components, what are those four components

driving anvil

locking collor



what should be the allowance of normal tail rivet an that of countersunk tail rivet.

normal tail rivet = 1.5D

countersunk tail = 0.75D

how would you rivets a thin sheets, and what is the process

by double dimpling (double countersunk)

a special dolly is used at first to form a mid stem countersunk

why is pre dimpling used
where the material is too thick
why should you use a cherry max rivet
after removing an unserviceable rivet (solid rivet) after which access is restricted to one side only
a rivet (pin) has a manufactured head on one end and a partially threaded shank with a recessed wrench hexagonal shape end on the other end, what is the name of the rivet
what is a rivnut
it is a blind rivet type which can be used as an anchor nut
how is rivnut installed
the rivet which ha an internal thread is inserted in to the hole, a threaded screw Is then inserted in to the rivnut and tightened until rivet forms (belches at the back)
