ND Color Code


ND Industries has developed special processing equipment for applying paint, dye or ink in virtually any color to the heads or tips of fasteners.

How it Works

Color-coding parts makes it easy to identify specific characteristics, such as: • Locking or Non-Locking • Right or Left-Hand Thread • Sealing or Non-Sealing • Unusual Dimensions • Size • Material • And more . . .


Assures Quality Control

Easier identification reduces the chance of improperly installed parts.

Easily identifiable parts speed any assembly process.

ND Patch will not dry, shrink, or lose resiliency when exposed to commercial solvents, alcohol, gasoline, oil, caustic soda, jet fuel, etc.

Versatile Processing

Color-coding can be applied to fasteners of any size, shape, material or finish in any quantity, from small lots to million-part production runs.

Simplifies Inventories

Color-coded parts are easy to identify and inventory.

Multiple Coatings

ND can also dual process color-coded fasteners with other quality ND fastener locking and sealing applications.


  • As with all our pre-applied products, ND Industries can apply ND Color Code onto your fasteners at any one of our regional service centers, or we can supply you with fasteners that contain a pre-applied ND Color Code.
