Hex Cap Screws, Stainless Steel 18-8, 1/4"-20 x 1-3/8", Partial Thread

Diameter - Thread Pitch: 1/4" - 20
  • 1/4"-20
  • Hexagon head designed to be driven by a wrench or socket
  • 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
  • Rust resistant in freshwater environments
  • For saltwater environments use the 316 stainless steel version

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.
