Description

These 5/16-18 x 1" serrated hex flange screws carry an integral washer face, spreading clamp load over a wider bearing area and removing the need for a separate washer. Case hardened steel with a black oxide finish.

  • Material and finish: Case Hardened Steel Black Oxide
  • Head style: Serrated Hex Washer
  • Surface hardness: Rockwell C40 minimum
  • Core hardness: Rockwell C25-38
  • Thread size: 5/16-18
  • Length: 1"
  • Thread style: Fully Threaded
  • Applications: Structural and chassis assemblies where a wide bearing face is needed

The serrations under the flange bite into the bearing surface and resist loosening under vibration, which is why this style is common in frame, chassis and equipment work. Torque to the specification for the joint rather than to a generic value. Hardness figures are the manufacturer published values and should be verified against the application.
