PEEK Hexagon Socket Screws Overview
PEEK Hexagon Socket Screws are high-performance fasteners manufactured from PEEK (Polyether Ether Ketone), one of the strongest and most chemically resistant engineering polymers available. Designed with a hexagon (Allen) drive recess, these screws are widely used in high-temperature, high-load, and chemically aggressive applications where metal fasteners may corrode, add unnecessary weight, or cause electrical interference.

Key Features
| Characteristic | Detail | Advantage over Metal/Standard Plastic |
| Mechanical Strength | Highest tensile strength, stiffness, and creep resistance of all plastic screws. | Approximates the strength of aluminum while being significantly lighter. Maintains integrity under sustained load and heat. |
| Thermal Resistance | Extreme Stability: Continuous use temperature up to $260^\circ \text{C}$ ($500^\circ \text{F}$). | Will not melt, soften, or creep in high-heat environments where Nylon or PTFE fail. |
| Chemical Resistance | Near-Universal Inertness: Excellent resistance to acids, bases, and organic solvents. | Immune to rust and galvanic corrosion, lasting longer than stainless steel in harsh chemical baths. |
| Drive System | Hexagon Socket (Allen Drive) | Allows for maximum seating torque compared to slotted or Phillips drives, ensuring a more secure, tight fastening. |
| Electrical/Magnetic | Excellent Insulator and Non-Magnetic. | Essential for electrical isolation and use in sensitive equipment like MRI machines or radar systems. |
| Purity | Ultra-High Purity: Non-leaching and non-contaminating. | Required in cleanrooms, pharmaceutical, and ultra-pure water (UPW) systems. |
Applications
PEEK Hexagon Socket Screws are utilized in mission-critical industries where their unique properties justify the high material cost:
Aerospace & Defense: Used for lightweight structures, internal components, and non-flammable assemblies.
Medical Equipment: Securing components in diagnostic instruments and sterilization equipment (autoclaves) due to bio-compatibility and heat resistance.
Semiconductor Manufacturing: Fastening parts in etching and chemical delivery systems due to supreme purity and resistance to aggressive media.
Industrial High Heat: Used in ovens, soldering equipment, and heat exchangers.
Scientific Instrumentation: Ideal for devices requiring non-magnetic, non-conductive, and chemically inert fasteners.
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.
