Benefits
- Grabber’s Pro-Fit™ # 2 Phillips recess is a precision recess designed for better bit engagement resulting in less wobble or strip-out.
- The modified truss head design provides a larger load bearing surface for better holding power. Under head serrations lock tight in metal to metal applications.
- Grabber fine thread modified truss head screws begin with the best available materials and conform to strict manufacturing requirements in thread forming.
- Grabber's extra sharp Streaker® point design starts immediately and is much less likely to flop over.
Recommended Application
Light gauge 18-30 mil (25-20ga) steel framing. K-lath installation.
Installation Guidelines
- Use a standard screwgun with a depth sensitive nose piece. Suggested screwgun specification for optimal performance – Size #6 - #10, up to 4,000 RPM.
- The Modified Truss Head is fully seated when the bearing surface of the head is flush with the work surface.
- The fastener must penetrate beyond the metal three full thread pitches.
- Overdriving may result in failure of the fastener or stripout within the substrate.
