Material/Finish
SNHS-HTF | |
---|---|
Main Body | SUSXM7 (Equivalent to SUS304)*1 PFA Coating (Head Only) |
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 PFA (Perfluoroalkoxy Alkane). This increases the chemical resistance of the screw head.
- Chemical Resistance of PFA ⇒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-HTF Sealing Washer ( coating) to prevent chemical liquids from moving from the bearing surface to the thread. SWS-HTF
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.
