- PEEK set screw features and benefits
PEEK set screws or Victrex® set screws are made from polyetheretherketone polymers and offer a unique combination of properties for some of the most extreme applications. PEEK set 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 set 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 set screws are well suited for applications in chemical processing, electronics, transportation, healthcare and other industrial uses.
Set screws made from customer specified PEEK grades are available upon request. See our online store (right side) for common PEEK screws or contact us for specialty or quantity requests.
PEEK set screws are unique in that they have no screw head, meaning that they have no protruding part past the threaded shaft. They are thread only and are available with a socket or slotted driver insert at one end. Set screws are used to secure an object within or against another object. Typically they secure a rotating part such as a gear or shaft. PEEK set screws are driven through a threaded hole in the rotating part until it is tight against the inner object, preventing from moving relative to the outer object. Set screws are available with various points depending on the application.
This is the most commonly used set screw and is identified by a cup-shaped indentation on one end. PEEK cup points are typically used for a quick, semi-permanent or permanent applications where it is acceptable to cut the cup point edge of the screw.
A cone point is easily identifiable by its sharp cone-shaped point – just like an ice cream cone. PEEK cone point set screws deliver the strongest clamping force due to the deep penetration of the point. As a result they are used for permanent assembly.
The cheapest and simplest of the set screw point styles, this screw has a flat surface on the bottom of the screw. This type is used when you need the ability to frequently change parts and require minimal shaft deformation.
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.
