OlyLog log screws have a patented head style and shank design that 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".
