The ultimate temperature resistant polymer
- Temperature resistant up to 300°C (572°F) continuous and 500°C (932°F) intermittent
- Low coefficient of friction and high wear resistance
- Chemically resistant to common solvents including acids, salts, and oils
- Low out gassing, low particle generation and inherent purity
- Unique physical, thermal & eletrical properties
- Vespel flat head screw features and benefits
Polyimide or Vespel® flat head screws are made from an advanced temperature resistant polyimide resin. Vespel flat head screws offer a unique balance of mechanical, thermal, and chemical properties for outstanding performance in a variety of demanding applications such as automotive, machinery, industrial equipment, aerospace, and semiconductor equipment.
Polyimide or Vespel screws also have the unique combination of properties such as excellent mechanical strength and toughness, exceptional radiation resistance, robust chemical resistance to many solvents, a low coefficient of thermal expansion, excellent creep resistance and flame retardance.
Vespel flat head screws are available in both metric and standard sizes. Contact us to learn more about polyimide screws or Vespel screws properties and availability.
Vespel flat head screws are characterized by having a head with a top flat surface (which can feature either a slotted, phillips or allen driver) and bottom that is cone shaped or countersunk. With this design, the head of the screw can align flush or below the surrounding surface having obvious benefits.

For most flat head screw designs the angle of countersink is usually 82° for UNC and UNF applications however other angles ranging from 60° -120° could be specified.
