NOTE

When replacing rivets during repair, use same rivet size and type, if possible. If hole has been damaged, it

will be necessary to drill hole oversize and use next larger rivet or oversize blind rivet.

After drilling and prior to driving rivets, parts to be joined must be secured to prevent slipping during riveting. C-

clamps may be used, or any of several varieties of skin fasteners may be inserted in previously drilled holes.

CAUTION

When riveting thin gage materials, be careful handling rivet tools to avoid damaging material.

Solid rivets are available in various lengths. Correct length rivet must be chosen so bucked head is not too small or

too large to form tight fit. Use Table 5 to determine proper rivet length.

Three common methods of driving or setting rivets are: hand, squeeze, and pneumatic gun. All three methods use

principle of upsetting or heading rivet shank against bucking bar.
