4" Log & Timber Screws - OlyLog

No pre-drilling required!

OlyLog is the first threaded structural log home fastener to require no predrilling.

Since its introduction, OlyLog has changed the way log homes are constructed.

Features:

• Installs faster and easier than lags & spikes

• Countersinks into log – Allows log to settle naturally

• Draws warped logs down

• Removable and reusable

• Eliminates jarring and damage caused by a sledgehammer

• ACQ approved

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.

Installation: 

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