PEEK pan head machine screws are non-metallic, machine-thread fasteners fabricated from PEEK (polyetheretherketone). They feature a pan head and standard machine threads and are designed for assembly into pre-tapped internal threaded holes — they cannot be used as self-tapping screws. Primary drive types include Cross Recessed / Phillips and Slotted. They are produced by both CNC machining and injection molding and comply with DIN7985 / ISO7045.
Compared with metal fasteners, PEEK pan head machine screws deliver high-temperature resistance, electrical insulation, non-magnetic performance, chemical inertness, low vacuum outgassing and far lower weight — making them a first choice for PEEK fasteners used in semiconductor, medical and corrosive-chemical equipment.
Cross recessed drive centres the driver automatically, reduces cam-out and is preferred for automated torque-controlled assembly lines, miniature M2 / M2.5 electronics fastening and high-volume production.
Single-slot drive allows the use of a flat-blade screwdriver and permits deeper recess cleaning — suitable for chemical equipment, laboratory instruments and manual maintenance where debris-free recesses matter.
GuangZhou Ideal is a Chinese manufacturer producing PEEK pan head machine screws through a combined process of CNC machining and mold injection molding. With 15 years of industry expertise, we have resolved diverse quality challenges arising from both processes and developed proprietary production standards.
PEEK is a highly elastic polymer. After metal toolpath threading, the thread profile exhibits minor elastic springback of 0.02–0.04 mm. We apply negative compensation to PEEK threading toolpaths to reserve allowance for polymer rebound. The finished 6g-class threads run smoothly without jamming or overtightening, eliminating assembly seizing.
The minimum residual wall thickness at the base of PEEK pan head screw Phillips or slotted recesses is ≥ 0.18 mm. Recess depth is reduced by 12%–15% relative to metal screw parameters. For miniature M2 / M2.5 sizes, recess depth is further optimized to prevent micro-chipping and hidden cracks.
Most manufacturers adopt a single universal shrinkage ratio, which causes defective threads for filled grades. Our proprietary segmented compensation logic: neat PEEK has uniform bulk shrinkage for consistent mold compensation; GF30 glass-filled PEEK shows significant longitudinal shrinkage and low transverse shrinkage requiring asymmetric mold compensation; carbon-filled PEEK suffers uneven density with localized micro-shrinkage, requiring secondary point-by-point fine trimming.
We adopt virgin high-purity Victrex 450G raw material with no mixed regrind. Post-processing includes dust-free ultrasonic degreasing cleaning to remove cutting oil residue and adsorbed particulates. Products are individually vacuum-sealed packed. TVOC low-outgassing test certification is available upon request.
Non-magnetic, insulating, low precipitation, chemically resistant — preferred for high-precision equipment.
High rigidity, high temperature resistance, good dimensional stability — but loses insulating, non-magnetic and vacuum-compatibility properties.
Anti-static, conductive and ultra-wear-resistant — only for ESD applications; completely non-insulating.
Strictly prohibited applications — material blacklist:
Pure PEEK: strictly prohibited for high-load, wear-resistant friction conditions.
GF30 glass fiber: strictly prohibited for semiconductor chambers, NMR equipment, high-voltage insulation and UHV vacuum.
Carbon-filled ESD PEEK: strictly prohibited for high-voltage insulation, NMR and semiconductor cleanrooms.
Unfilled PEEK pan head machine screws have a long-term continuous operating temperature of -196℃ to 250–260℃, with short-term peak temperatures reaching 300℃. The glass transition temperature (Tg) is approximately 143℃; exceeding this temperature under sustained load will result in creep and preload attenuation. GF30 glass fiber reinforcement significantly improves the heat distortion temperature; carbon filling also improves high-temperature rigidity.
Pure PEEK at 23℃ has a tensile strength of 95–110 MPa; its density is only 1.31 g/cm³, making it significantly lighter than stainless steel fasteners. It possesses good toughness. GF30 glass fiber reinforcement enhances rigidity and compressive strength. Carbon-filled PEEK significantly improves rigidity and wear resistance.
Pure PEEK pan head screws are self-lubricating, with a coefficient of friction of 0.3–0.35; they can be used in oil-free conditions. Carbon-filled and graphite-modified PEEK further reduces the coefficient of friction, significantly improving wear resistance.
Extremely low water absorption (< 0.5%), resulting in minimal dimensional change due to moisture. Low residual stress after annealing; unannealed products are prone to warping and cracking during thermal cycling.
PEEK pan head machine screws, with their high-temperature resistance, insulating and non-magnetic properties, low precipitation and chemical corrosion resistance, are widely used in precision assembly across multiple industries.
Used for securing components within wafer carriers and coating chambers. High-purity, unbleached PEEK reduces gas precipitation, preventing metal ion contamination of the wafer, and is suitable for plasma cleaning environments.
The non-magnetic nature and resistance to repeated high-temperature sterilization are used for assembling equipment components, eliminating imaging artifacts.
Used for fastening PCB circuit boards, battery pack insulation brackets and high-voltage electronic control components. Excellent insulation and UL94 V0 flame-retardant properties effectively mitigate the risk of short circuits and leakage.
Suitable for corrosive conditions such as acids, alkalis and electrolytes. Used for fastening electroplating tank baffles, filter components and anti-corrosion cabinet panels, replacing easily corroded metal fasteners and reducing equipment downtime for maintenance.
Used for tooling and equipment panel fastening in clean production lines. The dense material is easy to clean, with low leaching and no risk of impurity contamination.
Used in optical light-shielding baffles, analytical instrument clamps and chromatographic fluid components. Low deformation, non-magnetic and lightweight characteristics ensure precise assembly and alignment accuracy.
Carbon-filled PEEK cross recessed Phillips pan head screws are selected for anti-static fixtures and workshop tooling fastening, allowing for controlled static discharge. This material is not suitable for insulation, vacuum chambers or NMR equipment.
PEEK is a polymer: over-torquing causes thread stripping and delayed cracking. Use the recommended safety torque below and always confirm with a calibrated torque driver.
| Specification | Safety Torque (N·m) |
|---|---|
| M2 | 0.15 – 0.25 |
| M2.5 | 0.25 – 0.35 |
| M3 | 0.35 – 0.50 |
| M4 | 0.50 – 0.80 |
| M5 | 0.80 – 1.20 |
Safe disassembly and reassembly times ≤ 5. Reuse is prohibited in vibration, high-temperature and precision vacuum equipment.
Most suppliers only publish basic parameters and general-purpose advantages. As a Chinese manufacturer with fifteen years of experience producing PEEK pan head machine screws, GuangZhou Ideal addresses hidden polymer-material pain points with proprietary internal standards: thread spring-back compensation, anti-chipping slot wall-thickness specification, three-tier gradient annealing, anisotropic injection-mold shrinkage compensation, quantified creep-condition thresholds and standardized assembly torque guidance.
A strict material-grade application blacklist prevents magnetic disturbance, insulation failure and vacuum out-gassing pollution. Full-chain traceability and thermal-expansion-matching assembly advice solve common industry failures: delayed cracking, thread jamming, high-temperature loosening and drive-recess chipping. Reliable supplier for high-end custom orders in semiconductor vacuum, MRI medical-device and corrosive-chemical equipment.
GF30 contains metal oxides, which can cause magnetic interference and vacuum efflorescence contamination; carbon filler is a conductive material, which can cause short circuits and electrostatic runaway, damaging the operating conditions of precision equipment.
Indoors, they are permanently aging-resistant and will not deform; long-term outdoor UV exposure will cause surface powdering, so it is recommended to add a protective structure for outdoor use.
Under normal temperature static conditions, the lifespan is 8–10 years; under continuous high-temperature conditions of 200℃, it can be used for 3–5 years; vibration and frequent disassembly/reassembly conditions shorten the lifespan, so regular replacement is recommended.
Brand new high-purity PEEK has a uniform color, no dark spots, no micropores, low precipitation and good toughness; recycled materials are dark and yellowish in color, have many internal micropores, are brittle and have excessive outgassing. They are strictly prohibited from use in vacuum, medical and semiconductor applications.
Ordinary manufacturers omit precision annealing, leaving residual internal stress in the product. This defect is not visible at room temperature, but after thermal cycling and long-term stress, the stress is released, leading to delayed, latent cracking. Our three-stage gradient annealing completely solves this common industry problem.
Safe disassembly and reassembly times ≤ 5. Reuse is prohibited in vibration, high-temperature and precision vacuum equipment. Repeated disassembly and reassembly will cause micro-wear on the threads, hidden cracks in the grooves and eventual sudden breakage.
It is our exclusive stress-relief process, divided into industrial grade, precision grade and vacuum grade. It can completely eliminate the extrusion stress of the bar stock and machining cutting stress, and prevent delayed cracking and subsequent warping deformation caused by hot and cold cycles. It is a high-level process that ordinary manufacturers cannot achieve with single annealing.
