7.
flange
1/2” diameter
1/4” captive brass nut
fig. 7.4. Well-Nut is inserted
into a pre-drilled hole with
its flange against the outer
surface. There is no need
for access to the
inner side.

ing bracket is placed against
the flange of the Well-Nut
and is secured by the bolt
engaging the captive brass
nut.
flange
1/2” diameter
1/4” captive brass nut
fig. 7.6 . As the bolt is tight-
ened, the neoprene body of
the Well-Nut is compressed
and expanded, forcing it
tightly into the bolt's threads
and against the inner surface
of the thin rV roof material.
flange
1/2” diameter
1/4” captive brass nut
fig. 7.7. Installed in a blind
hole in a solid material,
the body of the Well-Nut
expands tightly against the
walls of the hole, effect-
ing a secure, dependable
fastening.
To install the Well-Nuts, drill holes 1¼” deep at the marked positions using a ½” size drill bit. Make sure
that drilling does not interfere with pre-existing wiring installations.
8. Apply silicone or any appropriate sealant recommended by your rV dealer generously to the drilled holes
for water-proofing.
9. Insert the ¼” Well-Nut into the drilled holes so that only the flange section remains above the roof
surface (fig. 7.4).
10. fasten the mounting brackets to the roof surface by inserting the ¼ x 1¼” serrated flange bolt into the
Well-Nut (fig. 7.5). Tighten using a 3/8” wrench to a recommended torque of 15 lbs. When the serrated
flange bolt is screwed into the Well-Nut, the material surrounding the well nut bulges slightly securing
the structure to the rV roof (fig. 7.6 & 7.8).
11. Make sure all bolts and mounting brackets are covered by good amounts of suitable rV sealant
recommended by your local rV dealer.
