What are PEEK Screws? 

Polyether Ether Ketone (PEEK) Screws are standard fasteners available in both metric and imperial systems that are manufactured using PEEK polymer material.

PEEK is an innovative semicrystalline thermoplastic that was developed to solve issues frequently encountered with other types of polymers, these include high temperature operation while maintaining mechanical strength and dimensional stability, high chemical resistance, Low thermal conductivity and other properties suitable for harsh industrial applications.

Key Properties of PEEK Screws include:

Exceptional chemical resistance
PEEK screws can only be dissolved in high concentrations of Nitric and Sulphuric acids.

Exceptional dimensional stability
Even at high temperatures (260°).

Low Radio Frequency noise 
Comparable to air.

Excellent weight to strength ratio
Specific gravity (1.30).

  • High heat operation (260°C)
  • High tensile strength (97mpa)
  • Ultra low weight 
  • Flame resistance 
  • Abrasion resistance
  • Hydrolysis resistance
  • Highly resistant to radiation
  • Non-Magnetic
  • Very low outgassing
  • Low thermal conductivity
  • Non-Corrosive

Top Industries Utilising PEEK Screws

Aerospace

The exceptional strength to weight ratio properties that PEEK screws contain enables them to be utilised within the aerospace industry. Low weight couldn’t be more essential within the aerospace sector as this allows for more efficient aircraft that are not compromised on strength and have higher fatigue resistance which in turn results in longer service intervals. 

Ultra-high Vacuum

PEEK Screws are commonly found in ultra-high vacuum systems due to low outgassing properties and resistance to extreme temperature; this makes PEEK Screws perfect when assembling ultra-high vacuum systems as it ensures high quality vacuums without risking excessive rates of outgassing.

Radioactive Environments

PEEK screws are highly radiation resistant; this makes the perfect type of fastener when dealing with particle physics. Equipment that is often used within range of neutron scattering can be fastened with PEEK Screws, thus reducing the amount of time the equipment has to ‘cool’ before being handled.

RF Systems

With the advancement of wireless systems, data transmission and networking, PEEK screws are regularly used in the Oil and Gas industry for high specification pipework monitoring devices. They are also used in 5G networking – predominantly within antennas and transceivers, eliminating potential interference caused by other fastener types and ensuring high speed/uninterrupted data transmission.and have higher fatigue resistance which in turn results in longer service intervals. 

Semiconductor Manufacturing

With the rapid growth of technological innovation the semiconductor industry is seeing a steep rise in production. Semiconductor manufacturing requires a lot of chemical processing, this makes PEEK screws the perfect fastener for equipment utilised within this growing industry due to its exceptional chemical resistance properties and ability to remain dimensionally stable at high temperatures.
