Olylog Log Home Screws

The OlyLog Log Home Screw is the first heavy-duty log home fastener that requires no predrilling, greatly reducing labor time. The self-countersinking design provides strong pull-down power, allowing logs to settle naturally. OlyLog Screws install more efficiently than lags and spikes, and eliminate the risk of damage caused by sledge hammers. Removable and reusable, OlyLog Screws are the fast and easy way to join logs.
