  • Removable and reusable
  • Eliminates jarring and damage caused by a sledgehammer
  • ACQ approved

OlyLog log screws have a patented head style and shank design makes these screws self-tapping and self-countersinking. OlyLog log screws are made of heat-treated steel for dramatically increased strength and durability. Each screw is "ultra coated" for unmatched corrosion resistance.



Use a 1/2", high torque, low RPM drill. Install OlyLog perpendicular to the log. Countersink a minimum of 1/4".
