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.
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. The wide flat-head design
counter-sinks below the log
surface. Log Boss
Fasteners maintain superior
pull-down power without
having to use a washer. The
six-lobe star head 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.

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.
