Tribological Dry Coatings for Fasteners
Tribological dry coatings are engineered to reduce friction, prevent galling, and extend the lifespan of threaded fasteners used in demanding applications. By applying a precisely formulated solid lubricant or composite layer, these coatings improve assembly consistency, long-term reliability, and corrosion resistance — without the need for additional oils or greases.
What Are Tribological Dry Coatings?
The term tribological refers to the science of friction, wear, and lubrication. In fastener technology, tribological dry coatings are thin, dry-film layers designed to optimize the interface between mating threads or contact surfaces. These coatings often include solid lubricants such as molybdenum disulfide (MoSâ‚‚), graphite, or PTFE, combined with resin or inorganic binders to create a durable, low-friction surface. Unlike conventional liquid lubricants, dry tribological coatings remain stable over time, resist contamination, and maintain consistent torque-tension relationships.
Key Benefits
- Reduced Friction and Galling – Lowers coefficient of friction for smoother tightening and controlled preload.
- Improved Wear Resistance – Minimizes metal-to-metal contact and surface degradation under high load or vibration.
- Stable Torque-Tension Relationship – Enables predictable clamping forces, critical for joint integrity.
- Corrosion Protection – Many tribological coatings incorporate anti-corrosion elements for long-term durability.
- Clean, Dry Surface – Eliminates the need for oil-based lubricants, reducing contamination and simplifying assembly.
- High Temperature Stability – Performs reliably in environments where liquid lubricants would degrade or evaporate.
