Lo-Root® Screws
Heat treated for greatest strength.
Sharp thread angle to cut into material to prevent splitting, cracking or bursting.
Optimum thread depth to thread spacing ratio to minimize crumbling between threads.
Thread surface nearly perpendicular to screw axis provides greatest resistance to pull out.
Minimum body diameter causing least material distortion.
Sharp point and rapid rise to provide easy penetration and full thread after first revolution.
