Category: Philips Flat Head Vent Screw WS2 Coated

Tungsten Disulfide, commonly known as WS2, functions as a dry lubricant coating with minimal friction. Applied using pressurized air, it creates a dry metallic coating without the necessity for heat, binders, or adhesives. The coating swiftly adheres to metal or resin, boasting a thickness of only 0.00002″ (1/2 micron).

WS2 coating outperforms other dry lubricants, improving fastener performance and extending service life by reducing friction and noise, enhancing mold release, and addressing potential issues such as excessive wear, seizing, galling, or fretting.


  • Reduced friction enhances fastener performance and extends its lifespan.
  • Prevents galling, fretting, and friction arising from differences in metal types and their varying hardness factors.
  • Provides 100% lubricity throughout its texture.
  • Molecularly bonds to the applied material.
  • Maintains fastener dimensional integrity within a 1/2 micron range, without any accumulation.
  • Withstands loads of up to 100,000 PSI.
  • Requires no bakeout or heat curing.
  • Functions effectively within a temperature range of -460°F to 1,200°F (-273°C to 650°C).
  • The coating is inert, inorganic, non-toxic, non-distortive, and resistant to most solvents.
