Powers wedge anchors are mechanical fasteners used to attach an item to solid concrete.  Powers Fasteners sells their wedge anchors under the brand name of Power-Stud™.  All Powers Fasteners brand wedge anchors can be purchased from Concrete Fasteners, Inc.

Description
A Power-Stud™ is a fully threaded wedge anchor with torque-controlled expansion designed for consistent performance in concrete.

Different Types
There are five types of the Power-Stud™:

• SD1 – provides standard performance; the anchor body and the expansion clip are made from carbon steel that is zinc plated.  This anchor provides consistent performance in cracked and uncracked concrete and is ICC listed ESR 2818 report.
• SD2 - provides premium performance because it is made from carbon steel that is zinc plated with a permanently installed expansion clip made from stainless steel.  Designed for consistent performance on cracked and uncracked concrete, and is ICC listed ESR 2502 report.
• HD5 – the body of the anchor is manufactured from carbon steel and then hot-dipped galvanized with the clip made from stainless steel; for use in solid concrete. These anchors do not have an ICC report and have not been tested for use in cracked concrete.
• SD4 - manufactured with a 304 stainless steel body and the expansion clip from 316 stainless steel, with a 300 stainless steel washer and a 316 stainless steel nut; designed for use in solid concrete.  These anchors do not have an ICC report and have not been tested for use in cracked concrete.
• SD6 - the anchor body, expansion clip, nut, and washer are all manufactured from 316 stainless steel. These anchors do not have an ICC report and have not been tested for use in cracked concrete.

Features and Benefits
All anchors listed above provide consistent performance in low strength as well as in high strength concrete.  The drill bit diameter used to drill the hole in the concrete is equal to the diameter of the anchor being installed.  The anchor can be installed through a hole in the item being fastened but the hole must be slightly larger than the diameter of the anchor being installed.  Each anchor is stamped on the head to allow for length identification once the anchor is installed in the concrete.

Installation
These installation instructions are an exact copy as posted by the manufacturer:

1. Using the proper drill bit size, drill a hole into the base material to the required depth.  The tolerance of the drill bit used should meet ANSI Standard B212.15.
2. Remove dust and debris from the hole using a hand pump, compressed air or a vacuum.
3. Position the washer on the anchor and thread on the nut.  If installing through a fixture into the hole, be sure that the anchor is driven to the minimum required embedment depth.
4. Tighten the anchor with a torque wrench by applying the required installation torque.
