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.
DeWALT powder actuated fasteners are specially designed and manufactured to
withstand the forces imposed during the driving operation. Only fasteners manufactured
or supplied by DeWALT 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
Washer
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

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.
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" (6.35mm) 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 reduces load
