Benefits
- The No. 2 square recess is a precision recess designed for secure bit engagement in light gauge metal to metal applications.
- Under head serrations lock tight in light gauge metal to metal applications.
- Grabber fine thread pan framing head screws begin with the best available materials and conform to strict manufacturing requirements in thread forming. Extra sharp twin lead thread screws drive faster and hold better in light gauge metal.
- Grabber’s extra sharp 23˚ Streaker® point design starts immediately and is much less likely to flop over.
Recommended Application
Cold-formed, light gauge steel framing. HVAC and sheet metal.
