Q & A
PEEK Fasteners – Engineering-Grade Performance in Extreme Environments
📄【PEEK Fasteners FAQ】
❓ Q1. What are PEEK fasteners typically used for?
👉 Semiconductor tools, chemical equipment, cleanrooms, electronics, and aerospace components—where high heat, chemical exposure, and metal-free environments are critical.
❓ Q2. How much heat can PEEK fasteners tolerate?
👉 Up to 240°C for continuous use, and short-term spikes above 300°C. They retain mechanical strength under extreme heat.
❓ Q3. Are PEEK fasteners resistant to acids and solvents?
👉 Yes. Excellent resistance to sulfuric acid, nitric acid, sodium hydroxide, acetone, and many organic solvents.
❓ Q4. Do PEEK screws and nuts maintain torque strength at high temperatures?
👉 Yes. PEEK maintains stiffness and creep resistance at elevated temperatures, making it suitable for load-bearing fasteners.
❓ Q5. Are PEEK fasteners suitable for cleanroom or vacuum applications?
👉 Yes. PEEK is low outgassing, halogen-free, and non-metallic—ideal for cleanroom, vacuum, and UHV (ultra-high vacuum) environments.
❓ Q6. Can I replace metal fasteners with PEEK in corrosive systems?
👉 In many cases, yes—especially where metal ions, corrosion, or magnetism are a concern. PEEK offers a non-metallic, inert alternative.
❓ Q7. What PEEK fastener sizes and standards are available?
👉 We offer Metric (M1.4–M16) and Inch (UNC/UNF) sizes. Head types: pan, socket, flat, hex., and more. Custom service available.
❓ Q8. Can PEEK parts be machined or customized?
👉 Absolutely. We support CNC machining, turning, thread cutting, and custom molding based on your drawings or specs.
❓ Q9. Is PEEK flame retardant?
👉 Yes. PEEK has a UL94 V-0 flame rating without additives, and generates low smoke and toxic gas under fire.
❓ Q10. Can PEEK fasteners be sterilized or autoclaved?
👉 Yes. PEEK withstands repeated autoclave cycles, gamma radiation, and chemical sterilants without degradation.
