Fastener Functioning
Prior to learning the safe operating
procedures for this tool, it is important
to understand how a powder actuated
fastener works. A powder actuated
fastener is considered to be a direct
drive or forced entry type of fastener
because it is driven directly into the
base material. The driving action causes tremendous forces
to be applied to the fastener. D
E
wALT powder actuated
fasteners are specially designed and manufactured using
an austempering process to withstand the forces imposed
during the driving operation. Only fasteners manufactured or
supplied by D
E
wALT should be used in this tool.
Functioning in Concrete
The performance of a powder actuated fastener when
installed into concrete or masonry base materials is based on
the following factors:
1. Strength of the base material
2. Hardness and concentration of the aggregate
3. Shank diameter of the fastener
4. Depth of embedment into the base material
5. fastener spacing and edge distance
In addition to these factors, installation
tool accessories such as a stop
spall which reduces the tendency of
the concrete surface to spall during
the driving action can increase the
performance of the fastener.
when a powder actuated fastener
is driven into concrete, it displaces the
volume of concrete around the embedded
area of the fastener shank. As this
occurs, the concrete directly surrounding
the fastener is compressed and in turn
presses back against the shank of the
fastener. Additionally, the driving action
generates heat which causes particles within the concrete
to fuse to the shank of the fastener. This combination of
compression and fusion holds the fastener in the concrete
base material. A similar action occurs when fastening into
block masonry.
Generally, the performance of the fastener in a given
concrete strength will increase with greater embedment
depths in a certain range. Depending on the fastener style
and base material strength, embedment depths range from
5/8” to 1-1/2”. for depths greater than this range, there is
the possibility of fastener bending or fishhooking which may
decrease expected load capacities and create a safety hazard.
During the driving action, some localized surface spalling
of the
concrete may occur. Normally, this is a surface effect which
does not effect the performance of the fastener. However,
it may pose an aesthetic problem for exposed applications
where a fixture is not used. In cases such as this, two
methods can be used to improve the appearance of the
fastening. A stop spall adapter mounted on the powder
actuated tool can help to reduce surface spalling. Another
method used is to drive the fastener through a steel washer
to improve the appearance of the application.
Functioning in Steel
The load performance of a powder
actuated fastener when installed into
steel base materials is based on the
following factors:
1. Thickness of the steel
2. Tensile strength of the steel
3. Shank diameter of the fastener
4. Depth of point penetration through the steel
5. fastener spacing and edge distance.
when a powder actuated fastener is driven into steel, it
displaces the steel laterally 360˚ around the shank of the
fastener. Since steel is an elastic material, it presses back
against the shank of the fastener to hold it in place. As the
diameter of the fastener shank is increased, the load capacity
obtained will generally increase provided the steel thickness
is sufficient to accept the fastener. To further increase
fastener performance in steel, some fasteners have a knurled
shank which allows the steel to form a key lock into the
grooves to provide higher capacities than those obtained with
a smooth shank. for optimum performance, the fastener
point should completely penetrate the steel. Normally, a
minimum of 1/4” is allowed for the point length. An increase
in performance can be expected until the fastener no longer
completely penetrates through the steel. At this point, the
elastic properties of the steel cause a compression force to
be developed at an angle against the fastener point which
