PEEK Hexagon socket set screw Overview

PEEK Hexagon Socket Set Screws are ultra-high-performance fasteners engineered from PEEK (Polyether Ether Ketone)—one of the most advanced engineering polymers available. Designed with an internal hex socket and a set screw body that contains no external head, these fasteners are used to secure components in place through compression or friction rather than clamping like traditional bolts.

PEEK hexagon socket set screws are chosen specifically when environmental conditions are too extreme for metal alloys (due to corrosion or conductivity) or for other polymers (due to heat or strength loss).

  • Extreme Thermal Resistance: Maintains mechanical integrity and strength up to continuous operating temperatures of 260°C(500°C).3

  • Superior Mechanical Strength: Offers high tensile strength and dimensional stability, crucial for maintaining a tight lock under load and vibration.4

  • Chemical Inertness: Highly resistant to virtually all common industrial chemicals, solvents, and corrosive agents, preventing fastener degradation.5

  • Electrical Isolation: Excellent electrical insulator, making it necessary for securing components near circuitry or high-voltage equipment.6

  • Non-Magnetic: Ideal for use in sensitive instruments like MRI machines and analytical equipment.7

Applications

These specialized set screws are employed in high-end, demanding applications:

  • Aerospace: Used in internal assemblies where lightweight, high-strength, and non-flammable fastening is required.

  • High-Temperature Fixturing: Securing thermocouples, sensors, or heating elements in ovens or processing equipment.

  • Semiconductor Manufacturing: Used in cleanrooms and wet-benches as adjustment stops or internal locking mechanisms due to PEEK’s zero-contamination properties.

  • Medical Equipment: Adjusting optics or securing internal non-magnetic components in diagnostic devices.

Advantages

  • Corrosion-resistant:  eliminates the problem of metal bolt rust.
  • Lightweight: Weighs only 1/5 of stainless steel, reducing load.
  • Insulated and anti-magnetic: Suitable for high-frequency circuits and strong magnetic field environments.
  • Long life: Fatigue resistance surpasses metal, extending maintenance intervals by three times.
  • Flexible customization: Supports custom sizes, colors, and performance enhancements.

Packaging & Delivery

Standard packaging includes PE bag, foam cover, and one double-deck corrugated outer carton for safety during transit. Delivery time is 5-15 working days depending on the quantity.
