Nycote® thread masking prevents weld spatter, electro-deposited paints, primers or coatings from adhering to the threads.

Nylok’s patented Nycote® coating process provides an affordable and efficient way of protecting fastener threads from weld spatter and electro-deposited paints, primers and coatings. Nycote® is a non-conductive powder thread coating that can be applied to virtually any fastener to add lubricity and reduce torque versus tension scatter.

Nycote® is widely used in industries such as agricultural, automotive, appliance, electronics, HVAC, machinery, marine, outdoor power equipment, recreation equipment and telecommunications manufacturing.


- Eliminates 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 electro-deposited primers and coatings.
- Prevents adhesion of weld spatter.
- Reduces torque versus tension scatter.
- Improves lubricity and reduces installation drive friction.
- Can be coated to external or internal threaded fasteners.
- Achieves known and repeatable clamp load.
- Guarantees good electrical grounding.
- Reduces manufacturing cost by increasing productivity.
- Coating is only on the threads, not grip length or faces.
