Our lags provide virtually no end load reducing worker fatigue by the ease of drive, deep sharp threads, no pre-drilling and more! Great for ledger boards, heavy timber construction, rigid foam insulation panels, post to beam and more!
- Triple SKT11 Exterior Bronze Coating on a high quality heat treated hardened steel. Rated for excellent corrosion resistance. Compatible with chemically-treated materials.
- Deepest Star Drive on the market! Star Drive Recess reduces camout and end load. Twice the torque of Phillips or square drive. Eliminates spinning and fastener damage. Two recess sizes (20 & 25) to match the torque requirements of the screw size. Gives better bit life.
- Type 17 Notched Extra Sharp Point starts quickly without walking, reduces need for pre-drilling, cuts through composite materials on first rotation.
- Tiny cuts on threads cut through fibrous materials and greatly reduces the torque needed to drive the screw without affecting holding power.
- Knurled shoulder reams hole in board being fastened, reducing drag on shank and driving tool.
- High quality heat treated hardened steel. True flat head with 16 cutting nibs self countersinks and prevents spinout.
