1. Clean the threads of any debris or rust using a wire brush or similar tool.
2. If specified apply wax to threads and bearing surfaces.
3. Place the nut on the anchor bolt and hand-tighten it until it’s flush with the anchor plate or structure.
   This is done to prevent any cross-threading that may occur.
4. Tighten nuts to a snug tight condition.
   Snug tight is defined by the AISC/RCSC as when all the plies in a connection have been pulled into firm contact by the bolts in the joint, and the bolts have been tightened sufficiently to prevent the removal of the nuts without a wrench. The AISC also states that in most scenarios, the normal effort of an ironworker with a regular spud wrench is sufficient to tighten the nuts to snug tight. If special pre-tensioning is required, the engineer should have carefully designed the anchor assembly specifically for that purpose and there should be detailed instructions so that the pretensioning is carried out properly.
5. Once snug tight is achieved tighten further to the designated value.
   This is often done using a torque wrench, most of which have an adjustable handle or a digital display to set the desired torque value. Consult the manufacturer’s instructions or the specifications provided for your wrench to learn how to adjust the torque setting. Apply the torque gradually, using a sequence of tightening in each pass so that the nut on the opposite side will be subsequently tightened. This helps distribute the load evenly across each bolt. Avoid sudden or jerky movements that could affect the accuracy of the measurement. Please be aware, because of the many interrelated variables that directly or indirectly affect friction, such as surface texture, finish, lubrication, speed of tightening, human error, etc., it is possible to experience as much as ±25% deviation in preload (clamp load) with the use of a torque wrench.
6. In some special applications, there are procedures for tensioning anchor bolts using a modified turn-of-the-nut methodology where a torque wrench is not required.
   The turn of the nut method is a guide that details the user to rotate the nut a specified amount depending on the bolt length and slope to achieve the required tension. The American Association of State Highway and Transportation Officials (AASHTO), in LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, details turn of the nut methods for the top nut in double nut moment connections. Identical to assembly using a torque wrench, these rotation recommendations are for after the nut is snug tight. Turn of the nut method is as follows: Once snug tight condition is achieved, establish reference marks, and then tighten the top nuts by turning each nut 1/12 turn (1/2 of a nut flat) past snug-tight using either static or impact tightening. Turn each top nut an additional 1/12 turn until each nut has been tightened 1/6 total turn past snug-tight.
7. Make sure there is proper thread engagement to achieve the full strength of the anchor bolts.
   Ideally, two full threads extend beyond the nut, however, this is often not the case. AISC Design Guide 1 writes that when the anchor rod is shorter than anticipated, it may be possible to partially engage the nut. An estimate of the resulting nut strength can be calculated based on the percentage of threads engaged on the condition that at least half of the threads in the nut are engaged.
8. Inspect the installation once the nut is tightened to ensure the assembly is securely fastened.
   Verify the nut is flush against the bearing surface and not misaligned or damaged.

Please remember these are general guidelines. It is recommended to consult the engineer on record before final assembly for specific applications.

Preparation and Safety

Before installing anchor bolts, it is important to take the necessary precautions to ensure safety and proper installation. This section will cover the steps you need to take to prepare for the installation of anchor bolts.

Assessing Load-Bearing Capacity

The first step in preparing for the installation of anchor bolts is to assess the load-bearing capacity of the surface you will be installing them on. This is important because it will determine the type and size of anchor bolts you will need. For example, if you are installing anchor bolts on a concrete surface, you will need to use concrete anchor bolts that are designed for heavy-duty applications.

Surface Cleaning and Alignment

Once you have assessed the load-bearing capacity of the surface, the next step is to clean and align it. This is important because any debris or misalignment can affect the stability and load-bearing capacity of the anchor bolts. To clean the surface, use a wire brush or compressed air to remove any debris or dust. Then, use a level to ensure that the surface is aligned properly.

It is important to wear protective gear such as gloves and safety glasses when installing anchor bolts. This will protect you from any debris or dust that may be generated during the installation process.

Installation Process

Installing anchor bolts can be a complex process, but with the right tools and knowledge, it can be done quickly and easily. In this section, we will cover the three main steps of the installation process: drilling and creating pilot holes, inserting and securing the anchor, and tightening and final adjustments.

Drilling and Creating Pilot Holes

The first step in installing anchor bolts is to drill the hole for the bolt. It is crucial to select the right drill bit size, which should be slightly larger than the diameter of the anchor bolt. This ensures that the bolt will fit snugly into the hole and provide a secure grip.

Next, create a pilot hole by drilling a smaller hole into the concrete. This helps to guide the anchor bolt into place and prevents the concrete from cracking. Use a hammer drill for best results.

Inserting and Securing the Anchor

After drilling the hole, it’s time to insert the anchor bolt. Make sure the threads are clean and free of debris before inserting the bolt into the hole. Once the bolt is in place, use a wrench to turn it clockwise until it is snug against the surface.

To secure the anchor, use a washer and nut. The washer should be placed against the surface, followed by the nut. Tighten the nut until it is snug, but be careful not to over-tighten as this can damage the anchor.

Tightening and Final Adjustments

The final step in the installation process is to tighten the anchor bolt. Use a torque wrench to tighten the nut to the manufacturer’s recommended torque value. This ensures that the anchor is properly secured and will not come loose over time.

If you encounter any issues during the installation process, such as difficulty drilling or inserting the anchor, or if the anchor bolt is not gripping the surface properly, contact Fastening Specialists for troubleshooting assistance.
