The Dagger-Lo LOPROT17GPCT1010 is a #10-13 x 1" Square Phillips Type 17 Clip Screw designed for fastening panel clips to wood and light-gauge metal in roofing, siding, and structural panel installations. Supplied in a bulk carton of 5,000 screws, this fastener is ideal for professional contractors and large-scale construction projects. Featuring a low-profile pancake head, the LOPROT17GPCT1010 provides increased bearing surface for secure fastening while maintaining a clean, low-profile finish. The Square/Phillips combo drive improves driver engagement and reduces cam-out during installation. Its Type 17 point helps eliminate pre-drilling and promotes faster penetration into wood and light metal substrates. Manufactured from carbon steel and protected with Dagger-Guard® coating, these clip screws provide excellent corrosion resistance, including up to 1,000-hour salt spray protection, making them suitable for demanding exterior applications.
