Perma-Chink's Log Boss Log Fasteners feature patented wings that reduce the friction between the wood and the shank and clear out the splinters created as the fastener pulls down into the wood.

 

This reduces the torque required to set the fastener into place. So if you want a fastener with maximum holding power and superior strength with less work, Log Boss is the answer.

 

These log fasteners were specifically designed by Perma-Chink Systems for the construction of log and timber structures. Their 3” long thread provides the grip necessary for pulling even the most difficult logs into place while the larger shank diameter increases the overall strength and pulling power.

 

The head of the Log Boss screws has been redesigned as well. These screws are now designed for better counter sinking and feature a 5/16” hex head driver.

This product comes in a pail of 250 fasteners. ***For 14" screws, the quantity of the pail drops to 150.***
