Guaranteed protection against thread contamination from electrodeposited paints, primers, coatings and adhesion of weld spatter on Drawn Arc Weld Studs.


Nylok's patented NYCOTE® NYCREST™ coating provides all of the advantages of our NYCOTE® product while also eliminating material buildup on collets. Our unique patented process (U.S. #5685680) coats the root and flank of the thread without coating the crest. The resulting fastener provides solid metal to metal contact between the thread and collet, which eliminates material buildup on the collet thereby eliminating the costs associated with collet replacement and lost production.

NYCOTE® NYCREST™ is Nylok's WHITE® PFA Fluorocarbon powder thread coating that:
  • Eliminates expensive masking, plugging or capping of threads
  • Eliminates the need for "slave" bolts
  • Eliminates re-tapping which can compromise quality and safety
  • Prevents the adhesion of electrodeposited primers and coatings
  • Prevents adhesion of weld spatter
  • Reduces torque vs. tension scatter
  • Improves lubricity and reduces installation drive friction
  • Coats external or internal threaded fasteners
  • Achieves known and repeatable clamp load
  • Guarantees good electrical grounding
  • Reduces manufacturing cost by increasing productivity
  • Coats only the threads - not grip length or faces

Today, NYCOTE NYCREST™ is widely used by manufacturers in the agricultural, automotive, appliance, electronics, HVAC, machinery, marine, outdoor power equipment, recreation equipment and telecommunications industries.
