Fastenmaster LOG004

FastenMaster OlyLog is the original threaded log home fastener engineered to deliver superior performance in log construction. Designed to countersink into the log, OlyLog allows the structure to settle naturally over time-an essential requirement for long-term stability in log homes. Its unique design also draws warped logs down tightly, improving fit and reducing gaps during installation.

Unlike traditional spikes or lag screws, OlyLog eliminates the jarring impact and potential damage caused by sledge-hammer installation. It drives smoothly, requires no predrilling, and provides consistent, professional-grade results in both softwood and hardwood logs.

Perfect for log home builders, timber installers, and contractors, OlyLog delivers a faster, easier, and more reliable fastening solution for modern log construction.
