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. Powers 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 Powers
Fasteners 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

NOTE
— JUST AS NO ONE CAN MERELY READ A BOOK ABOUT DRIVING AN AUTOMOBILE AND THEN HOPE TO RUN IT SAFELY, NO ONE
SHOULD ATTEMPT TO USE ANY POWDER TOOL WITHOUT ADEQUATE, COMPETENT, PERSONAL INSTRUCTION. AND, JUST AS NO AUTOMOBILE
INSTRUCTION BOOK OR INSTRUCTOR CAN FOREWARN A LEARNER AGAINST ALL CONTINGENCIES AND EMERGENCIES, NEITHER CAN POWERS

PRODUCTS. THE MANUFACTURER DISCLAIMS RESPONSIBILITY FOR INJURIES TO PERSONS OR PROPERTY WHICH MAY RESULT FROM DISREGARD
OF THESE OPERATING INSTRUCTIONS.
Introduction
Thank you for purchasing the Powers PA351 low velocity powder actuated tool. This tool
will provide you with excellent performance provided the steps for proper operation and
maintenance are followed. Powder actuated fastening systems can provide a cost effective
method of attaching fixtures for light duty, static load conditions. The systems provided by
Powers Fasteners consist of specially designed fasteners, installation tools, and powder loads
which are designed to function in combination to provide optimum performance. While powder
actuated tools can provide one of the fastest and economical means of fastening, they can also
be dangerous if they are not operated properly.
Prior to operating the PA351 tool, you must be properly trained in the operation and
maintenance of this tool and be issued a Powers Fasteners Qualified Operator Card. When using
the tool, you must have this card in your possession. As part of the training process, you should
read and understand the contents of this instruction manual especially the safety precautions.
Powder actuated tools may be operated only by properly trained operators as described in ANSI
Standard A 10.3, Safety Requirements for Powder Actuated Fastening Systems. For complete tool
operation details, contact your local Powers Fasteners Branch office or distributor
for training.
Remember, safety begins with you! It is your primary responsibility when operating this tool.
Failure to follow the proper operating, maintenance, and safety procedures can result in serious
injury or death to yourself or bystanders. In addition to the training provided, you should be
familiar with any local, state, and federal regulations. If you have any questions which are not
covered in this manual, contact your local Powers Fasteners Branch office or distributor.
