PEEK Screws

PEEK screws are superior kinds of industrial fasteners produced from poly ether ketone which is a brittle and powerful kind of polymer.
Owing to these different fine mechanical properties they can subsequently withstand high temperature; be attacked or corrosive environment and possess low coefficients of friction.
PEEK screws can be used for a variety of different specialist engineering applications.

Characteristic advantages of PEEK screws

6 major advantages tell you why you choose injection molded peek screws

Process characteristics: PEEK screws are directly cured by single injection molding (molding temperature: 380-400°C, mold temperature: 160-180°C), without the need for secondary heat treatment (such as tempering).
Shrinkage rate: only 0.1-0.3% (much lower than ordinary engineering plastics), ensuring dimensional accuracy (in compliance with ASTM D955 standards).

After immersion in strong acids such as 20% hydrochloric acid and 50% sulfuric acid for 1000 hours, the mass loss is less than 0.1%;
Salt spray test (ASTM B117) 5000 hours without rust, better than 316 stainless steel (only 2000 hours).

Density: 1.3 g/cm³ (vs. 7.9–8.0 g/cm³ for stainless steel, 4.5 g/cm³ for titanium).
Weight Reduction: 1/6 the weight of stainless steel screws, enabling 15–20% payload optimization in aerospace systems.

Short-Term: Retains >80% tensile strength (90–100 MPa initial, ASTM D638) after 1,000 hours at 260°C.
Thermal Limits: 160°C HDT (1.8 MPa, ISO 75), 343°C melting point (ISO 11357).

Permittivity (ε): 3.2–3.3 at 1 MHz, with <5% variation from -50°C to 250°C.
Dissipation Factor (tanδ): 0.001–0.003 at 1 MHz, stable across frequencies.

Durability: Maintains >90% mechanical properties after 10⁶ Gy gamma irradiation (ASTM D1879).
Nuclear Applications: 10+ years service life in reactor cooling systems, doubling corrosion resistance vs. metal fasteners.

BWPEEK screws are commonly employed in wet processing equipment to secure components.

Within photovoltaic wet processing, PEEK screws help ensure reliable equipment operation under demanding conditions, supporting efficient solar cell production.

Chemical resistance: Resists acids (such as HF, HNO₃), alkalis and solvents, preventing equipment failure or product contamination caused by corrosion of metal screws.
High-temperature stability: Retains physical properties in high-temperature steam or aqueous environments, suitable for continuous wet processes.
Non-conductive and low contamination: Prevents metal ion contamination of sensitive semiconductor or photovoltaic materials, ensuring high-purity production.
Lightweight and high strength: Reduces equipment weight, enhances fatigue resistance, and extends service life.

Yes, PEEK (Polyether Ether Ketone) fasteners are quite appropriate in most industrial applications especially where other metal or nylon fasteners might fail because of corrosion, high temperature, or exposure to chemicals. This thermoplastic substance has an outstanding mechanical strength, thermal stability up to 260 °C (500 °F), low friction and wear resistance that make it suitable in aerospace, oil and gas, semiconductor manufacture and chemical processing industries. These also have good insulation properties that shield against electrical shocks in electronic systems and they are non-conductive, which is advantageous in an electromagnetic-sensitive environment.
