Wedge-Bolt™ |
| 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. | |

| NOTE: The values listed above are ultimate load capacities in pounds which should be |
| reduced by a minimum safety factor of four or greater to determine the allowable working |
| load. Refer to the Fastening Systems Design Manual as published by Powers Fasteners, |
| 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. |

| Rs | 1.00 | 0.90 | 0.80 | 0.70 | 0.60 | 0.50 |
| Edge Distance - Tension |
| An edge distance, E, of 12 anchor diameters (12d) should be used to |
| obtain the maximum tension load. The minimum recommended edge |
| distance, E, is 5 anchor diameters (5d) at which point the tension load |
| should be reduced by 20%. The following table lists the load reduction |
| factor, Re, for each anchor diameter, d, based on the anchor center |
| to edge distance. |

| Edge Distance - Shear |
| For shear, an edge distance, E, of 12 anchor diameters (12d) should be |
| used to obtain the maximum shear load. The minimum recommended |
| edge distance, E, is 5 anchor diameters (5d) at which point the shear |
| load should be reduced by 50%. The following table lists the load |
