Product Description

Product Description

The 90° cup washer is a machined steel part available for ASSY countersunk head screws ASSY Ecofast and ASSY VG CSK. The washer provides a proper bearing for the screw head in steel to wood connections without reaming out a steel plate.

Features

  • 1/4″ [6 mm]
  • 5/16” [8 mm]
  • 3/8” [10 mm]
