Material/Finish
| SNHS-HTF | |
|---|---|
| Main Body | SUSXM7（S.S. grade：A2）＊＊ Teflon＊Coating（Head Only） |
＊Teflon is a registered trademark of DuPont.
＊＊The baking finish during coating changes the color of the screw thread.
Application
FPD production equipment, semiconductor fabrication wet processes,
printed circuit board etching devices, metallic surface treatment
equipment and facilities, cleaning equipment, and chemical plants
Characteristics
- Only the screw head is coated with Teflon. This increases the chemical resistance of the screw head.
- Chemical Resistance of Teflon Coating⇒Chemical Resistance of Chemical Resistance Screws
- To increase chemical resistance, the coating membrane is thickened (to approximately 50 μm). The screw thread is not coated so thread precision is not affected.
- Use with SWS-TF Sealing Washer – Teflon Coating to prevent chemical liquids from moving from the bearing surface to the thread.SWS-TF
Precautions for Use
- Friction during tightening may remove the coating. Take care not to tighten too much. Apply the recommendation torque or lower for tightening.
- For tightening, use a socket wrench with a hexagonal socket.
