ITW Redhead, a division of Illinois Tool Works, has been manufacturing concrete fasteners for the construction industry since 1910. The first anchor that Redhead manufactured was called the self-drilling anchor. Many other innovations have followed throughout the years. Concrete Fasteners carries a complete line of RedHead anchors as well as equivalent types that are ready for shipment from their world headquarters in Cleveland, Ohio.
Includes three categories: adhesive, mechanical and screw-type anchors. The following article will concentrate on the mechanical and the screw-type anchors.
A broad range of mechanical anchors is available for use in different types of base.
Concrete Only – These anchors should only be used in solid concrete and should never be used in other masonry base materials, such as brick or block
- Trubolt Wedge Anchor – comes packaged with the correct number and size of nuts and washers, and has a stainless steel expansion clip permanently attached. Manufactured in zinc plated, carbon steel, hot-dipped galvanized 304 stainless steel or 316 stainless steel. Each stud is stamped with a length identification letter for easy embedment depth inspection after the anchor is installed. The diameter of the hole drilled in the concrete is equal to the diameter of Trubolt being installed. It can be installed through the fixture being installed, thus eliminating hole spotting. The Trubolt does not use the bottom of the hole to expand, which allows the hole depth to exceed the anchor length.
- Trubolt+ Seismic Wedge Anchor – designed specifically for seismic applications, is compliant with IBC (International Building Codes of 2006 and 2009) and listed by ICC-ES and the City of Los Angles. As with all wedge anchors, the diameter of the hole to be drilled in the concrete is equal to the diameter of the Trubolt being installed.
- OVERHEAD Seismic Trubolt+ - Same as above but comes with a rod coupling instead of a nut. Approved for cracked concrete/seismic applications in concrete with a metal deck.
Concrete and Masonry - These anchors can be used in both solid concrete as well as other base materials, such as brick or block.
- Dynabolt Sleeve Anchors – One of the most versatile types of masonry fasteners. Comes in zinc plated carbon steel and stainless steel and is available in an acorn head, hex head, flat head or round head. They are made up of three parts: the split expansion sleeve threaded stud body with expander and nut and washer. They are sold completely assembled. Their anchor diameter is equal to the diameter of the sleeve anchor being installed, and they are manufactured in diameters from 1/4” to 3/4” and lengths of up to 6-1/4”.
- Hammer Set Anchors – are not to be used in overhead applications, have a low profile mushroom head and are not able to be removed once set. They are fast and easy to install, work great in concrete, brick or block, and can be installed through the material being fastened. They anchor bolt and expander drive pin comes preassembled in one piece.
The original Tapcon brand masonry anchor, as well as the large diameter tapcon and the 410 stainless steel tapcon, are designed to provide high performance.
- Large Diameter Tapcon - often just called an LDT, it cuts its own threads into concrete. Made from a grade 5 steel and plated with zinc. The anchors have a finished hex washer head with the washer having anti-rotation serrations to help prevent the anchor from backing out. Each head is stamped with a length identification code for easy inspection after being installed.
- Tapcon Blue Climaseal Masonry Screw – the original masonry anchor that cuts threads into most masonry material and is still manufactured in the United States of America. These high-performance screws are fast and easy to install, with no hole spotting necessary. They come in either a hex washer head or a flat Phillips countersunk head. Installation is as easy as drilling a hole in the masonry with the correct diameter bit and then running the screw in. They are manufactured in two diameters: 3/16” and 1/4” with each diameter having a number of lengths.
- 410 Stainless Steel Tapcon Silver Climaseal – same as the original tapcon manufactured in two diameters with a hex or flat head. The flat head in the stainless steel is only available in the 3/16” diameter. The minimum length of the screw to use for any specific application is determined by adding the thickness of the material being fastened to the minimum embedment of 1”.
