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 PROVIDE 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
C A U T I O N
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 number.
For double dimpled sheets, add countersunk head height to materials
thickness to prevent damage to equipment.
Prior to installing blind rivets, hole must be prepared and parts must be alined
and clamped firmly in place. These steps are the same as for solid riveting
operations (refer to Rivet Hole Drilling, above).
Proper drill sizes for standard and oversize blind rivets are
Countersinking dimensions and minimum sheet gage for
rivets are shown in Tables 3 and 4.
given in Table 2.
Grip lengths are determined as shown in Table 7.
Use rivet installation tool kit, D-100-MIL-1, and puller head adapters, if required,
for all blind rivets.
