1.1 Introduction
As we enter the new millennium, Powers Fasteners is proud to
introduce a revolutionary new anchoring product that is so simple
yet so technologically advanced that it will revolutionize the field of
anchoring. Just as the wedge anchor replaced the self-driller, the new
Wedge-Bolt will replace the wedge anchor. Anchors that are simple
and easy to install are better. There is less likelihood of improper
installation, therefore better performance. The Wedge-Bolt is
a universal high strength carbon steel anchor designed for use 
in most base materials such as concrete, block, brick or stone. It
is a versatile,high performance anchor that is vibration resistant and
removable. Available with a finished hex washer head in 1/4", 3/8",
1/2", 5/8", and 3/4" diameters,it is easy to install offering a foolproof
alternative to the most commonly used anchors on the market.
1.2 Product Description

The Wedge-Bolt is a one-piece unit featuring a finished hex head formed
with an integral washer, a patented dual lead thread, and a chamfered
tip. A one piece design eliminates the possibility of lost parts or
improper assembly while the patented dual lead thread design
provides optimum load performance and resistance to vibration. It
is a versatile anchor that can be used in a variety of base materials.
Installation of the Wedge-Bolt anchor is simple and easy. Using a
special matched tolerance Wedge-Bit drill a hole into the base material.
Since the hole size for the Wedge-Bolt is the same as the anchor size,
the need for layout or hole spotting is eliminated. The Wedge-Bolt is
designed to match standard fixture clearance holes that are 1/16" over
nominal. To have a full thread diameter product work with a standard
clearance hole, a special diameter bit is required. Once the hole is
drilled, clean it, then press the chamfered tip of the anchor through
the fixture into the hole, and tighten it using a socket wrench or
impact wrench. It's that easy. The driving or hammering step used
with typical anchors is eliminated along with any requirement for
assembly. This ensures the fastest possible installation.
Optimum performance is obtained through the unique design of the
Wedge-Bolt anchor. On the working end of the anchor, a chamfer is
formed to center it in the anchor hole as it is inserted through the
fixture into hole drilled in the base material. The patented double
lead threads also help center the anchor in the hole and provide
resistance to load once the anchor is installed. Since the Wedge-Bolt
can be used in a variety of base materials, the need to stock assorted
anchor types and learn a variety of installation procedures is eliminated.
As the anchor is tightened into the hole, the reverse parabolic double
lead threads undercut the wall of the hole. The double thread is formed
with a high helix angle for fast entry and advancing. A specially design
relief thread formed in the body of the anchor allows easy tightening at
a reduced torque level and provides a dust relief to prevent jamming of
the anchor. This feature allows the anchor to function at both shallow
and deep embedment depths. Unlike typical expansion anchors, the
double lead threads grip a large portion of the embedment length. This
provides consistent, high load capacities and low slip. The high clamping
force developed combined with the low slip characteristics of the
Wedge-Bolt provide excellent resistance tovibration. High tension load
capacities often allow the Wedge-Bolt to be used at a shallower
embedment than typical anchors which reduces drilling and installation
costs. The high shear load capacities allow use of smaller diameters
when compared to typical anchors further reducing installation costs.
Since there are no expansion forces, the Wedge-Bolt anchor can be
installed closer to the edge than traditional mechanical anchors. Unlike
adhesive anchors, the fixture can be loaded immediately. Once the
anchor is fully seated against the fixture, the ratchet teeth on the
underside of the hex washer head engage the fixture to provide
additional resistance to vibration. Installation is not only fast and easy,
the controlled "screw-in" method is safer than the hammer driving
method used with traditional anchor types. When the installation is
complete, the finished hex washer head provides an attractive
appearance. It is also safer than many traditional mechanical anchors
where exposed thread above the nut creates a tripping hazard. For ease
of identification after installation, the head of the anchor is stamped
with both the diameter and length. In addition to the easy installation
and high performance, the Wedge-Bolt anchor is also removable. Unlike
traditional anchor types, it can be removed to accommodate installation
errors such as improperly drilled or unclean anchor holes. Many fixtures
such as those used in forming applications are temporary requiring a
removable anchor. The Wedge-Bolt anchor is easy to remove, leaving a
neat clean hole with no components remaining in the base material. For
fast, easy, cost effective high performance installations, the Wedge-Bolt
anchor is the one product that does it all.
1.3 Installation Procedures

1 . Using the proper diameter Wedge-Bit, drill

a hole into the base material to a depth of at
least 1/2", or one anchor diameter deeper
than the embedment required. Be sure to use
a Wedge-Bit. Blow the hole clean of dust and
other material. Insert the anchor through
the fixture into the anchor hole.
2. Begin tightening the anchor by applying

for ward pressure when engaging the first few
threads. Continue tightening the anchor until
the head is firmly seated against the fixture. In
extremely dense materials, use of an impact
wrench is recommended.
3. Be sure the anchor is at the required

embedment depth and that the maximum
torque has not been exceeded. The
installation is now complete.
For proper installation, a Wedge-Bolt must be installed with a Wedge-Bit.
1.4 Anchor Sizes
The following tables list the sizes of hex head Wedge-Bolt anchors.
The anchor length published is measured from below the hex washer
head to the end of the anchor. To select the proper length, determine
the embedment depth required to obtain the desired load capacity.
Then add the thickness of the fixture, including any spacers or shims,
to the embedment depth.

Inc. for details on anchor design and Installation.
1.8 Design Criteria
Base Material Thickness
The minimum recommended thickness of base material, BMT, when using
the Wedge-Bolt is 125% of the embedment to be used. For example,
when installing an anchor to a depth of 4", the base material
thickness should be 5".

Spacing Between Anchors
To obtain the maximum load in tension or shear, a spacing, S, of 10
anchor diameters (10d) should be used. The minimum recommended
anchor spacing, S, is 5 anchor diameters (5d) at which point the load
should be reduced by 50%. The following table lists the load reduction
factor. Rs, for each anchor diameter, d, based on the center to center
anchor spacing.
