1/4"-20 Black Oxide Stainless Steel Button Head Socket Cap Screws

Screw Diameter - Thread Pitch: 1/4"-20

1/4"-20 Button Head Socket Cap Screws are bolts or machine screws with a Hex or Allen drive style.

  • Commonly referred to as allen bolts, button heads, or socket head screws
  • Clean and unstamped domed head with a flat bottom that protrudes above the installation surface
  • Cylindrical head and hexagonal drive style
  • Head diameter is nominally 1.5 times or more that of the screw shank (major) diameter
  • Chemically treated to add a mild extra layer of corrosion and abrasion resistance
