Blind Rivet Driving Practices and Precautions.
Rivets should be inspected for proper installation. Grip length of each rivet is marked on top of rivet head to pro-
vide positive identification. Use of proper grip length will produce rivet installation where locking collar is flush
with top surface of rivet head. Tolerance limit on flushness is 0.020 in (0.5 mm).
For proper rivet installation, it is imperative that holes be properly prepared, tools be in good working order, and
rivets be properly applied. When problems occur, source of trouble could be in any of these areas.
Blind Rivet Installation.
Proper length rivet must be selected for each application to prevent damage to equipment. Rivet lengths
are sized by range of material thickness that rivet will grip.
Rivets can tolerate only 1/16-in variation in material thickness for each particular rivet length to prevent
damage to equipment. Rivet grip lengths are called out as dash number at end of manufacturers part
For double dimpled sheets, add countersunk head height to materials thickness to prevent damage to
Prior to installing blind rivets, hole must be prepared and parts must be aligned and clamped firmly in
place. These steps are the same as for solid riveting operations (refer to Rivet Hole Drilling on page
Proper drill sizes for standard and oversize blind rivets are given in Table 2.
Countersinking dimensions and minimum sheet gage for countersunk blind rivets are shown in Tables 3
Grip lengths are determined as shown in Table 7.
Use rivet installation tool kit, D-100-MIL-I, and puller head adapters, if required, for all blind rivets.
