Description

These 5/16-18 x 7/8" frame bolts carry an integral indented hex flange flange head, which spreads clamp load over a wider bearing area and removes the need for a separate washer. Built from Grade 8 Steel with a black phosphate finish.

  • Material and finish: Grade 8 Steel Black Phosphate
  • Head style: Indented Hex Flange
  • Grade: Grade 8
  • Thread size: 5/16-18
  • Length: 7/8"
  • Applications: Structural and chassis assemblies where a wide bearing face is needed

The serrations or flange face resist loosening under vibration, which is why this style is common in frame, chassis and equipment work. Torque to the specification for the grade and joint rather than to a generic value.
