1.ALWAYS know the thickness and type of base material into which you are
fastening. NEVER GUESS. Test the base material by using the Center Punch
Test. The Center Punch Test is performed by using a hammer to test drive the
particular power fastener to be used into the material. If the point penetrates
easily, the material is too soft. If the point becomes blunt, the material is too
hard. If the material fractures, cracks or shatters, the material is too brittle. Test
fastenings can be made if the material shows a clear fastener impression and
the fastener point is not blunted. Always start with the lowest powder load
(Gray-Level 1) and proceeding with the order shown in the lower right-hand
figure above. ALWAYS wear approved eye protection.

Page 12
Why A Power Fastener Holds
482-65
WHY A POWER FASTENER HOLDS
IN CONCRETE
The compression bond of the concrete to the power
fastener accounts for the majority of the holding power.
The fastener displaces the concrete which tries to return
to its original form causing a squeezing effect.
Maximum holding power is achieved when the
depth of penetration produces a bond on the power
fastener equal to the strength of the concrete. As a
general rule, penetration should be approximately 1"
to 1 1/4" into the base concrete. Make sure the concrete
is at least three times as thick as the intended fastener
penetration. NEVER have the power fastener point protrude thru the concrete.
NOTE: Concrete needs to cure for 28 days before
maximum fastening holding power will be achieved.
WHY A POWER FASTENER HOLDS IN STEEL
Holding power in steel depends on the elasticity of
the steel. The steel pushes back on the shank of the
power fastener.
Drop a marble into water; the water parts, the
marble continues down, the water closes back. This is
similar to the reaction when a power fastener penetrates
steel.
In steel, the point of the power fastener must
penetrate completely through for highest holding power.
If the fastener does not penetrate, the spring action of the
steel pushes back on the point and tends to force the
fastener out.
Recommended applications are between 3/16-3/8"
steel.
482-64
NOTE: When fastening in steel be sure the point goes
thru the steel.
10
Page 13
Selecting Power Fasteners
G 018
and Powder Loads
FASTENING INTO CONCRETE
The proper power fastener length can be determined
by adding the thickness of the material to be fastened and
the amount of fastener that will actually penetrate the
concrete. The concrete must be three times as thick as the
intended fastener penetration. In most cases, penetration
should be approximately 1" to 1 1/4" into the base concrete
material.
FASTENING INTO STEEL
The proper fastener length can be determined by
adding the thickness of the material to be fastened and the
thickness of the steel. The point of the power fastener
must go completely through the steel.
Wood or Non-Metals
To Concrete
Wood or Non-Metals
To Steel
482-85
482-79
POWDER LOADS
Always start with the lowest power level (gray-level
1). If the first test fastener does not penetrate to the
desired depth, move to the next highest power level
(brown-level 2). Increase until a proper fastening is made.
IMPORTANT: Damage to the tool will result if the above
instructions are not followed (see illustrations to right and
lower right).
OVERDRIVEN POWER FASTENERS
AND PISTON
An overdriven power fastener results when too
strong of a powder load is used causing the piston to
extend past the muzzle. Move to the next lightest powder
load. Repeated overdrive will damage your tool. By avoiding overdrive, you can extend the life of your tool considerably and avoid costly repairs.
NOTE: NEVER fire the tool without a power fastener. This
can damage the tool and/or cause possible injury to the
operator.
IMPORTANT: DO NOT use power fasteners longer than
2 1/2". Fasteners longer than 2 1/2" will cause load
ejection problems.

the muzzle against the work surface. Again press the tool firmly against the
work surface and pull the trigger. If the tool still fails to fire, hold the tool firmly
against the work surface for another 30 seconds before unloading and carefully
discarding the misfired powder load into water or oil.
