Hex Cap Screws, Stainless Steel 18-8, 5/16"-24 x 1-3/4", Partial Thread

Diameter - Thread Pitch: 5/16" - 24
  • 5/16"-24

  • Also called hex cap bolts, hex bolts, tap bolts or hex cap screws
  • 18-8 Stainless steel hex cap screws offer protection from weather and corrosive environments

A hex cap screw in smaller sizes may not have a shoulder. When a hex cap screw is fully threaded it can also be referred to as a tap bolt.

Hex Bolts are measured as: Diameter x Thread Pitch x Length from Under Head
FT: Fully Threaded
PT: Partially Threaded

**1/4"-20 Hex Cap Screws listed as PT, usually have a threaded portion of about 3/4".
However, this can vary slightly from manufacturer to manufacturer.
