Description

Socket Countersunk (Csk) Head Screws - Product Information

Socket Countersunk (Csk) Screws are heat treated to give a 12.9 strength grade level, although service load ability in application is equivalent to strength grade 10.9 due to the geometry of the fastener.

The head angle for metric countersunk socket screws is 90 degrees up to & including M20 and 60 degrees over M20. The head angle for Imperial is different – Unified is 80 degrees and British threadforms are 90 degrees.

  • Metric range from M3 to M24 diameter
  • Imperial range from No. 0 to 1.1/4″ diameter
  • Stainless Steel available – including A2, A4, B8, B8M
  • Lot traceability available
  • Various finishes available
