Fastener Notes

  • On the 12 mm fairlead use metric 6 mm unless using a socket head cap screw; only 6 mm hex heads fit.
  • Only hex-head bolts allow one-person through-deck mounting: the head is held by the sides of the inset.
  • On the 14 mm range only the one- and two-hole models take hex heads, and need a flat-bladed screwdriver wedged between bolt head and pocket.
  • Choosing the correct screws, nuts, washers or threaded plates for the loads is the installer's responsibility.

Mounting

  • Mount on a flat area of deck, reinforced if necessary to take a load equal to the breaking load of the fairlead.
  • Marine epoxy and G10 suppliers are good sources of deck reinforcement techniques; if in doubt, consult the builder.
  • Drill carefully and slightly bevel the top of each hole so the sealant forms a small ring at deck level.
  • Fill the hole and bevel with marine sealant and use every fastener hole.
  • Fasteners in A4 (316) or A2 (18-8) stainless, with large washers or backing plates and locknuts under deck.

Failure to ensure the correct deck strength can result in the fairleads pulling off the deck suddenly and unexpectedly under high load.

Inspection and Maintenance

  • Carefully inspect fairleads and mounting hardware for loosening, cracks or damage.
  • Clean by frequent flushing with fresh water.
  • Teak cleaners and other caustic solutions can discolour the part; this is not covered by the Harken warranty.
