Post installed inspection of the Titen HD® heavy-duty screw anchor is simple because the length of the anchor is stamped on the head of the anchor. During an inspection, the embedment depth of any particular anchor can be determined by subtracting the length of the Titen HD® heavy-duty screw anchor above the surface of the base material from the total length of the anchor. Drill Bit Requirements Post-installed concrete fasteners need to be placed a minimum distance from an unsupported edge. The rule of thumb for expansion anchors is five times the diameter. The Titen HD® heavy-duty screw anchor’s minimum distance from an unsupported edge is 1-3/4” for all diameters. Titen HD® Inspection The anchor includes a hex-washer head for a cleaner installed appearance. No separate washer is necessary unless it is required by code. The hole in the fixture needs to be larger in diameter than the diameter of the Titen HD® heavy-duty screw anchor being installed. It is very important to make sure that the Titen HD® heavy-duty screw anchor being installed will fit through the fixture hole before the hole in the base material is drilled. See the chart below for the dimensions of the recommended hole diameter in the fixture: Titen HD® Diameter The drill bit used to drill the hole for the anchor must meet ANSI standards. Hole size is equal to anchor size. The diameter of the anchor being installed is equal to the hold diameter that is drilled into the base material. For example, if the Titen HD anchor is 3/8-inch, then the hole must be 3/8-inch.

All Titen HD® heavy-duty screw anchors come with a hex washer head that does not require the use of a separate washer. The hex head leaves a very clean look once installed with no stud or nut protruding above the fixture. The hex washer head is serrated, giving the Titen HD® heavy-duty screw anchors very good vibration resistance once the head of the Titen If the Titen HD® heavy-duty screw anchor will not install completely, remove the anchor from the hole. Ensure that all dust is removed from the hole or drill the hole deeper. Then reinstall the Titen HD® heavy-duty screw anchor by hand to prevent any cross threading from occurring. Titen HD® Product Information Corrosion Resistant— For dry, interior applications, carbon-steel corrosion is not a risk, but in any kind of exterior, coastal or chemical environment the anchor would be susceptible to corrosion. With the introduction of the THDSS, there is finally a state-of-the-art anchor solution that combines the corrosion resistance of Type 300 Series stainless steel with the undercutting ability of sacrificial heat-treated carbon-steel cutting threads. Many of these products are approved for installation with Strong-Drive® SD Connector screws. Model No.Mechanical galvanizing meets ASTM B695, Class 65, Type 1. Intended for some pressure-treated wood sill plate applications. Not for use in other corrosive or outdoor environments. See Supplemental Topics for Anchors or visit www.strongtie.com/info for more corrosion information.

Post-installed inspection of the anchor can be performed in a snap because the length is stamped on the anchor’s head. Embedment depth of any particular anchor has to be calculated. To determine the depth, simply subtract the length of the anchor above the surface of the base material from the total length of the anchor. These models do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. – lb. using a torque wrench, driver drill or cordless 1/4" impact driver with a maximum permitted torque rating of 100 ft. – lb. With a hammer drill and a carbide bit that meets ANSI standards and the same diameter as the Titen HD® heavy-duty screw anchor being installed, drill a hole in the base material. Drill the hole a minimum of 1/2” deeper than the Titen HD® heavy-duty screw anchors will penetrate. Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified embedment depth plus minimum hole depth overdrill (see table below) to allow the thread tapping dust to settle, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping.

Type 300 Series stainless-steel screw anchors have different corrosion-resistant properties for different environments. When matched to the appropriate environment and application, anchors made from Type 300 Series stainless steel will resist the effects of corrosion and maintain their strength and integrity. Each anchor bolt requires a standard-cut washer. The Simpson Strong-Tie® Titen HD® heavy-duty screw anchor does not require a washer. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern. Spacing requirements for the Titen HD® heavy-duty screw anchor are less between anchors and an unsupported edge because the Titen HD® heavy-duty screw anchor is not an expansion anchor and does not exert force against the base material. The minimum spacing requirements for all diameters of the Titen HD® heavy-duty screw anchors is 3” Titen HD® Minimum Edge Distance

Models THDC25238CS6SS, THD37212CS and THD37212CS6SS do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. – lb. using a torque wrench, driver drill or cordless 1/4" impact driver with a maximum permitted torque rating of 100 ft. – lb. From testing to service to availability, everything we do is engineered to ensure your project's success. With every product, you know you are getting the quality, value, service and on-time delivery that we have built our reputation on for the past 60 years. For design in accordance with the IEBC Chapter A3, the URFP may be used as a one-for-one replacement for the alternative connections shown in Figures.Align the hole in the fixture with the hole in the base material and insert Titen HD® heavy-duty screw anchors through the fixture hole and into the hole in the base material. Patented Torque Reduction Channel that traps dust where it can’t obstruct the thread action, reducing the likelihood of binding in the hole

Mechanical galvanizing meets ASTM B695, Class 65, Type 1. Intended for exterior application and some interior pressure-treated wood sill plate applications. See Supplemental Topics for Anchors.It is easy to remove, so it’s ideal for temporary anchoring of formwork, bracing, or for applications where fixtures may be moved. The Titen HD® heavy-duty screw anchor is manufactured in carbon steel that is heat treated, and is available in zinc plating or a mechanically galvanized finish. Codes and Approvals Spacing between the anchor and an unsupported edge is less than other types of anchors because the Titen HD anchor is not an expansion anchor and does not apply energy against the base material. As a result, the minimum spacing required for all diameters of the Titen anchor is 3-inches. Availability with either a hex head or, for a smoother installed profile, a T30 6-lobe-drive countersunk head Prescriptive" denotes spacing requirements per the IEBC and designs per the IRC and conventional provisions of the IBC.
