WHAT IS A LOG BOSS LOG SCREW?
Log Boss is a log and timber fastener designed to deliver maximum holding power and superior strength with less installation effort. Each Log Boss Fastener has 3 full inches of super aggressive thread that provides the grip necessary for pulling even the most difficult logs into place. The larger shank diameter increases the overall strength and pulling power of the fastener.
Specifically designed for the construction of log and timber structures, Log Boss Fasteners are rust-resistant, require no pre-drilling and come coated with a lubricant for quick and easy driving. Log Boss Fasteners maintain superior pull-down power without having to use a washer. The hexhead design helps prevent driver slippage. The relief wings located just above the threads act as a reamer allowing the shank of the log screw to rotate much easier and with less friction in the top of the log you are screwing down.

WHAT ARE RELIEF WINGS AND WHY DO I NEED THEM?
One of the most outstanding features of the Log Boss Fasteners is the relief wings located just above the threads. The wings act as a reamer allowing the shank of the log screw to rotate much easier with less friction in the top log you are screwing down. Without the wings the wood fibers bind up on the shank to the point it becomes almost impossible to complete driving to the required depth.
WHAT LENGTH LOG BOSS SHOULD I USE?
Select a Log Boss Fastener length that will allow the threads to pass entirely through the first log and thread fully into the second log. In general this means that your Log Boss Fastener should be 3 inches longer than the log being fastened down. The reason for this is simple. In order for the screw to accommodate log movement, it must be anchored only in the bottom log with the head providing pull down pressure on the top log. It is better to use a log fastener which is a little longer than you need to make sure that the threads will pass completely through the first log.
WHAT'S THE BEST WAY TO INSTALL LOG BOSS FASTENERS?
A 1/2 inch electric power drill is recommended. For electric drills with adjustable speeds, use the lowest speed setting. When using rechargeable drills set the drill on the highest torque setting and lowest speed. Always wear eye protection when working with any type fastener and power tool.
