(b) Back up the flush or nonflush rivet with a block of wood or a bucking bar, and center punch the center of the
manufactured head.
(c) Using a drill 0.031 of an inch (0.8 mm) smaller than the rivet shank, drill through the head of the rivet so that the
drill does not damage the skin or cut the sides of the rivet hole.
NOTE:
(d) Insert a drift punch into the hole drilled in the rivet and tilt the punch to break off the rivet head.
(e) With a drift punch and hammer, drive out the rivet shank while you support the opposite side of the structure.
3. Blind Rivets
A. General.
(1) Blind rivets are intended for use where access is only available to one side of the work. Refer to Fasteners - General,
for the limitations on the use of blind rivets.
B. Installation.
(1) Blind rivets are installed with special tools, in the holes specified in Hole Size and Edge Distance. After insertion,
check the rivet for correct installation.
C. Checking.
(1) After installation, if the rivet stem and collar are flush within the limits described in Figure 2, the rivet is correctly
installed with a satisfactory blind head and lock formed.
D. Removal.
(1) Obtain a drill bit of the correct size for the blind fastener to be removed. Refer to Figure 3.
(2) Place a drill bushing over the stem so that it rests squarely on the lock collar.
(3) Using a drill of 1250 RPM maximum, drill to collar depth.
(4) Drive the stem from the sleeve with a pin punch of correct diameter.
(5) Remove any remaining portion of the lock collar.
(6) Adjust micro-limit tool to within 0.005 to 0.015 inch (0.13 to 0.38 mm) less than dimension X.
(7) Press anti-rotation cap of tool firmly against head of fastener sleeve.
(8) Counterbore stem to necessary depth.
(9) Drive sleeve out using punch having same diameter as fastener's nominal diameter.
(10) If the fastener was countersunk-head type, remove head from countersink.
4. Hi-Lok Fasteners
A. General.
(1) The Hi-Lok fastener has a threaded pin and collar. The pin contains a hexagonal shaped recess allowing installation
from one side of the work.
B. Installation (Refer to Figure 4).
(1) Hi-Lok fasteners are usually installed with special tools. When these tools are not available, Allen hex keys and open-
end or ratchet-type wrenches can be used. The collar must be tightened until the collar's wrenching device has been
torqued off.
C. Removal (Refer to Figure 4).
(1) Installed Hi-Lok fasteners can be removed with special tools or common hand tools. In non-interference fit holes, an
Allen hex wrench is used to prevent pin rotation while the collar is unscrewed with pliers. In interference fit holes,
installed fasteners are more easily removed with special tools. If the pin was not damaged during collar removal, it
can be used again.
5. Swage Lock Pins
A. The swage lock pin fastener system uses a high strength pin and a collar of a softer metal to form a high strength structural
fastener. The collar is swaged into annular locking grooves in the pin to produce a permanent, tight, vibration resistant
fastener which cannot loosen or back off under vibration.
B. The swage lock pin is removed by splitting the collar either manually with a cutting chisel or with a powered splitting tool
and then driving the pin from the hole. Refer to Figure 5.
