Plastic Screw (PFA:Socket Head Cap Screw)

SPFA-C

PFA is a plastic that is excellent for its heat-resistance, electrical properties, chemical-resistance, and special friction-wear characteristics. It is also impenetrable by most chemicals.
Excellent nonviscous and lubricating properties.
Heat-resistant Temperature: 260°C (UL Approved Temperature)
Excellent flame resistance: Meets UL 94 V-0 Standard.
Useful for chemical-resistant applications such as FPD (Flat Panel Display) and semiconductor production equipment/ devices, printed circuit board etching devices, metal plating equipment, and chemical plants.
Use with a nut to compensate for thread molding pitch errors. When a nut is not used, it is recommended that the overlap of mating screw threads be shorter than 20mm.
Please refer to Plastic Screw Characteristics for more information on the special properties of plastic screws and cautions concerning their use.
Screw Length Adjustment is available on request.
Material/Finish:
PFA (Perfluoroalkoxy) (Translucent white)
