Typical Installation of a Well-Nut
7. 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.

tightened, the neoprene
body of the Well-Nut
is compressed and ex-
panded, forcing it tightly
into the bolt's threads
and against the inner
surface of the thin RV
roof material.
