Bronze Socket Head Screws

Stronger than brass screws and more corrosion resistant. These screws are often used in marine environments, industrial pumps, and valves. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.

Length is measured from under the head.

Silicon Bronze—More resistant to salt water than brass screws. They're also stronger and more resistant to abrasion and wear.
