Weight Comparison Analysis

The comprehensive weight data demonstrates that even the largest M6 x 35mm Peek screws weigh only 2.28kg per thousand pieces, showcasing remarkable weight savings compared to traditional metal fasteners that would weigh approximately 15-20kg for equivalent quantities.


Important Considerations for Peek Screw Weight Specifications

Key Performance Benefits:


  • Material density of 1.30-1.32 g/cm³ versus 8.0 g/cm³ for stainless steel
  • Excellent chemical resistance, maintaining weight stability in harsh environments
  • Operating temperature range from -40°C to +250°C with minimal thermal expansion
  • Superior fatigue resistance ensuring long-term weight consistency

Critical Selection Factors:


  • Thread pitch variations can affect overall weight by ±5% from standard specifications
  • Head style options (socket cap, button head, countersunk) impact individual piece weight
  • Manufacturing tolerances per ISO 4762 standards ensure ±3% weight accuracy
  • Batch-to-batch consistency maintained through rigorous quality control protocols

Cost-Benefit Analysis:


  • Initial material cost offset by significant weight reduction advantages
  • Reduced shipping costs due to lower overall package weight
  • Enhanced performance in weight-critical applications justifies premium pricing
  • Long service life reduces replacement frequency and associated labor costs

Advanced Weight Calculations for Industrial Applications

Density-Based Weight Formulas

Peek material density ranges from 1.30-1.32 g/cm³, significantly lower than stainless steel's 8.0 g/cm³. This fundamental difference enables precise weight calculations using standard volumetric formulas for cylindrical and threaded components.


Temperature-Dependent Weight Variations

Operating temperatures can affect Peek screw dimensions marginally, with thermal expansion coefficients of approximately 47 x 10⁻⁶/°C. For precision applications requiring exact weight specifications, temperature compensation factors should be applied to base measurements.


Sourcing Peek Screws Through B2B Portal Networks

Professional procurement teams increasingly rely on specialized b2b portal platforms for sourcing high-performance fasteners. Advanced platforms like pipex.ai offer comprehensive product databases with detailed specifications, ensuring engineers access accurate weight charts and technical documentation essential for project success.


Quality Standards and Weight Verification

ISO Compliance Requirements

Peek screws manufactured to ISO 4762 standards maintain consistent weight tolerances within ±3% of specified values. This precision ensures predictable performance characteristics across different manufacturing batches and suppliers.


Testing Protocols for Weight Verification

Standard weight verification procedures involve precision analytical balances capable of measuring to 0.1mg accuracy. Batch sampling protocols typically require testing minimum 10 pieces per production lot to ensure compliance with published specifications.


Applications Where Weight Charts Matter Most

Medical device applications demand precise weight calculations for implantable components, where every milligram affects patient outcomes. Aerospace applications require detailed weight documentation for compliance with stringent weight budgets and center-of-gravity calculations.


Chemical processing equipment benefits from Peek screws' corrosion resistance while maintaining detailed weight records for equipment balance and structural calculations.


Conclusion

This comprehensive weight reference guide provides essential data for engineering professionals working with Peek fasteners. Accurate weight specifications enable precise project planning, cost estimation, and performance optimization across diverse industrial applications. Regular consultation of updated weight charts ensures project success and regulatory compliance in demanding operational environments.
