PEEK (POLYETHER ETHER KETONE)

Grub/Set Screws

PEEK ‘Grub’, also known as set screws have many applications due to their high temperature and chemical resistance.

HPP stock grub/set screws that feature a hexagonal drive-type for use with a hex key (sizes are given in the dimensions table above).

An application in which our PEEK grub/set screws have been used is within scientific research. A rotating stage with an aluminium holder designed to house a polished silicon block needed grub/set screws to ensure that the block was pressing against the face of the holder which coincided with the centre of rotation within the rotating stage. PEEK grub screws were enlisted for this application due to their radiation resistance while also maintaining a high tensile strength and not damaging the polished block while clamping.

Key Properties of PEEK Grub/Set 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
  • Food safe (FSA/FDA Approved)
