WHAT IS A LOG BOSS FASTENER?

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.

• Pre-drilling is not required
• No washer needed
• Drive it one time and forget it
• Flat head design easily countersinks to maximize pulling power
• Replaces the need for spikes or lag bolts
• Lubrication coating speeds installation time
• Relief wings prevent shaft binding
• 6 lobe star drive keeps driver from slipping
• Tru-Kote coating exceeds FM4470 corrosion standards

WHY DO LOG BOSS FASTENERS HAVE A FLAT HEAD?

The design of a log screw is very critical to overall performance and ease of use. Unlike other fasteners the Log Boss has a 6 Lobe Recessed Drive with flathead rather than a socket head drive. The 6 lobe T 40 Drive provides for the most positive engagement of the drive bit to prevent cam out of the driver. The large flathead easily countersinks to just below the log’s surface to reduce driving torque on the drill. Reducing the torque decreases the strain around the wood fibers, which increases the holding power of the wood fibers between the threads. This design eliminates thread strip out.

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.

HOW FAR SHOULD YOU DRIVE A LOG BOSS IN?

Unlike socket head fasteners, Log Boss Fasteners need only to be driven down slightly below the surface. Due to the high amount of pull down with the flathead design it is important not to overdrive the fastener.

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.
