Product Introduction

SM Fastners offers a complete range of high-performance PEEK (Polyether Ether Ketone) fasteners that are ideal for applications where metal fasteners fail due to corrosion, weight constraints, or electrical interference. PEEK is a high-performance engineering thermoplastic known for its extreme chemical resistance, high-temperature endurance (up to 250°C), mechanical strength, and excellent insulation properties.

Our PEEK fasteners are widely used in semiconductor equipment, aerospace components, offshore platforms, nuclear facilities, and high-voltage electrical environments, where reliability and performance are non-negotiable.

We provide standard and custom-machined PEEK fasteners manufactured with tight tolerances and certified for technical and regulatory compliance.

Types of PEEK Fasteners We Offer

Our PEEK fasteners are available in metric and inch dimensions, including:

  • PEEK Bolts (Hex / Socket / Flat Head)
  • PEEK Nuts (Hex, Dome, Wing, Custom)
  • PEEK Screws (Pan Head, Socket Head, Countersunk, etc.)
  • PEEK Washers (Plain, Spring, Insulated)
  • PEEK Threaded Rods
  • PEEK Bushes and Spacers
  • PEEK Custom Machined Components (as per drawing or sample)

  • We support custom CNC machining and precision tolerances down to ±0.01 mm for cleanroom or aerospace-grade parts.

Why Use PEEK Fasteners?

PEEK fasteners are metal-free, non-conductive, and suitable for the harshest industrial conditions:

  • 🔥 High Temperature Resistance: Continuous use up to 250°C (482°F), short-term up to 300°C
  • 🧪 Chemical & Acid Resistance: Tolerant to solvents, acids, seawater, hydrocarbons, and alkalis
  • ⚡ Electrical Insulation: Dielectric strength of 16–20 kV/mm, non-magnetic, non-conductive
  • 🚀 Low Weight: 85% lighter than steel, ideal for aerospace and automotive applications
  • 🌡️ Dimensional Stability: Maintains mechanical strength in steam, cryogenics, or vacuum conditions
  • 🧼 Low Outgassing: Ideal for semiconductor and vacuum chamber usage
  • 🌱 Non-toxic & FDA Compliant: Safe for food and medical-grade environments

Applications

PEEK fasteners are critical where conventional metal bolts and screws corrode, spark, or conduct electricity:

  •  Semiconductor & Cleanroom Equipment – Used in wafer fabrication, ion implantation, and electrostatic-sensitive equipment.
  •  Aerospace & Aviation – Weight-saving structural components in satellites, aircraft interiors, and radar enclosures.
  •  Electrical & Power Transmission – PEEK acts as an insulator in switchgear, transformers, and battery enclosures.
  •  Oil & Gas / Offshore Platforms – High-pressure and corrosion-prone environments benefit from PEEK’s resistance and sealing strength.
  •  Nuclear & Defense – Non-metallic parts used in reactors, submarines, and radiation-exposed systems.
  •  Medical Devices & Labs – Non-reactive fasteners for sterilization equipment, MRI-safe installations, and test rigs.
