Applications The anchor is made from Carbon Steel, and is Zinc Plated. This anchor is designed for use in Concrete only, and should never be used in block or brick base material.
Environment The anchor is designed for use in a dry environment.
Hole Diameter/Bit Diameter The anchor requires a 3/4" hole to be drilled in the base material (Concrete only). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill.
Diameter of Anchor The diameter of the anchor is 3/4".
Length Anchor The length of the anchor is 8-1/2"
Thread Type The threads on the anchor are national coarse threads that measures 3/4" with 10 threads per inch, commonly referred to as 3/4"-10.
Thread Length The length of the threads on the anchor is 6" in length.
Packaging The anchor is packaged with 10 pieces per box and is packaged with the correct number and diameter of nuts and washers.
Depth of Hole The depth of the hole that is required for the anchor should be a minimum of 1/2" deeper than the anchor will penetrate the concrete. This will allow space for dust created during the installation process to fall, which will prevent the anchor from bottoming out in the hole before full penetration into the concrete.
Fixture Hole Diameter The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 3/4" diameter anchor requires the hole in the fixture to be 7/8".
Wrench Size The size of the wrench required to turn the nut to set the anchor is 1-1/8".
Torque Value To be set properly in the concrete, the anchor must be torqued to between 150 ft./lbs.
Bolt Length When a bolt is used in conjunction with the anchor, the length of the bolt needed is determined by considering these factors:
Flush With Concrete - when the anchor is set flush with the surface of the concrete, add the thickness of the material being fastened to the thread length of 6", and then add the space for any washers used.
Below Surface of Concrete - add the depth below the surface of the concrete to the thickness of the material being fastened, then add the space for the washer, and, finally, add 6" for the thread engagement.
Installing a 3/4" x 8-1/2" Strong-Bolt® 2 Wedge Anchor (ea) STB2-75812
Drill a 3/4" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
Drill the hole a 1/2" deeper than the anchor will penetrate the concrete, making sure the minimum embedment requirements of See PDF is met.
Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
Insert the point of the 3/4" x 8-1/2" Strong-Bolt® 2 Wedge Anchor (ea) STB2-75812 into the hole. Make sure that the screw being installed will penetrate the base material a minimum of 1" but no deeper than 1-3/4".
Turn the screw clockwise, applying slight pressure until the head of the screw is snug against the material being fastened.
Always use proper personal protective equipment per manufacturer's and OSHA instructions.
