Hex head is held
by sides of inset.

Hex head* bolts are ideal for one-person though-deck fastening.
The hexagonal head is held by the sides of the inset when being tightened.
Note: In the 12 mm version, only 6 mm hex head bolts will fit.

Choose fasteners that are made from A4 (316) or A2 (18-8) stainless steel. Make
sure to use large washers or backing plates and lock washers or locknuts under
deck. It is installer's responsibility to choose correct screws, nuts, washers, or
threaded plates, taking account materials and loads they will have to bear. Harken
assumes no responsibility for incorrect installation of fairleads or for an incorrect
choice of mounting fasteners.

Deck Strength

Fairleads must be installed on a flat area of deck, reinforced if necessary to bear a load equal to the
breaking load of fairlead to be used. Marine epoxy suppliers are a good source of deck reinforcement
techniques. Also contact suppliers of G10 reinforcement. It is installer's responsibility to carry out all
structural tests needed to ensure that deck can bear load. Consult the yard that built the boat in case of
doubt over the suitability of mounting location and deck strength. Harken

®

assumes no responsibility

for incorrect installation of fairlead or for an incorrect choice of mounting screws.

WARNING! Failure to ensure the correct deck strength type can result in the fairleads pulling off the
deck suddenly and unexpectedly during high loads.

Mounting Fairleads

Carefully drill holes. Slightly bevel the top of the hole to allow sealant to
form a small ring at deck level. Use marine sealant, making sure sealant
fills hole and beveled area. Secure fairlead using all fastener holes. Secure
under the deck using large washers or backing plate and washers and
locknuts.

Slight bevel allows
sealant to form a
ring at deck level.

Inspect

Carefully inspect fairleads and mounting hardware for any signs of loosening, cracks or damage.

WARNING! Failure to inspect fairleads and mounting hardware can result in fairleads pulling
off deck suddenly and unexpectedly during high load.

Maintenance

Clean by frequently flushing with fresh water.

IMPORTANT! Exposure to some teak cleaners and other caustic solutions can
result in discoloration of part and is not covered under the Harken warranty.
