Benefits

The Phillips recess is a precision recess designed for better bit engagement resulting in less wobble or cam-out.
The Bugle Head screws are more evenly heat treated and tempered resulting consistent and reliable performance.
Extra sharp alternating or high-low threads are designed to drive quicker and provide better holding power in drywall to light gauge metal or wood applications.
The extra sharp 23˚ Streaker® point design starts immediately and is much less likely to flop over.

Recommended Application

Drywall attachment to light gauge steel or wood.

Installation Guidelines

Use a standard screw gun with a depth-sensitive nose piece. Suggested screw gun specification for optimal performance - Size #6 - #10 up to 4,000 RPM.
The Bugle Head is fully seated when the screw is below the surface of the wallboard in accordance with Section 7.2.2 of ASTM C1002.
The fastener must penetrate beyond the metal three full threads.
Overdriving my result in fastener failure or strip out of the work surface.
