- Excellent strength, and stiffness up to 500°F (260°C)
- Low coefficient of friction and high wear resistance
- Chemically resistant to common chemicals including acids, salts, solvents, oils and steam
- Low out gassing, low particle generation and inherent purity
- Unique physical, thermal & electrical properties
- PEEK flat head screw features and benefits
PEEK or Victrex® flat head screws are made from polyetheretherketone polymers and offer a unique combination of properties for some of the most extreme applications. PEEK screws are known for their excellent wear resistance, best in class fatigue resistance, high purity and excellent chemical resistance to organics, acids and bases.
Depending on the application, PEEK flat head screws can be reinforced with glass fibers for improved strength and stiffness properties. Reinforced PEEK screws offer greater mechanical robustness especially in applications beyond 350°F (175°C).
PEEK flat head screws are well suited for applications in chemical processing, electronics, transportation, healthcare and other industrial uses.
Screws made from customer specified PEEK grades are available upon request. See our online store (right side) for common PEEK flat head screws or contact us for specialty or quantity requests.
PEEK 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.
PEEK Slotted vs. Phillips Driver
|Slotted Head Advantages||Phillips Head Advantages|
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.
|Thread Type||Normal Flat Head Countersink Angle|
UNC / UNF
|ISO Metric / Imperial||90°|
Common PEEK Screw Grades
PEEK 100% / Unfilled
PEEK, with no fillers is unreinforced and 100% polymer. Even without glass or carbon fiber reinforcement, this one of the strongest polymers we offer and well suited for a variety of applications including FDA food contact and other applications requireing high purity.
PEEK Glass Fiber Reinforced
PEEK 30% Glass Fiber Reinforced provide the same chemical resistance and natural PEEK but nearly doubles in tensile strength.
PEEK Carbon Fiber Reinforced
PEEK 20% Carbon Fiber Reinforced provides approximately 2.5 times the strength of pure PEEK.
PEEK Extreme is our proprietary receipe for the highest strength PEEK utilizing carbon fiber reinforcement. This version of PEEK over 3 times stronger than standard unreinforced PEEK.
