Wedge anchor1/8/2023 ![]() This is what enables them to fasten the object to the concrete. Tapcons are self-tapping screws that tap their own holes when being driven into a material. Another difference between them is in their fastening method. ![]() However, the wedge anchor suits heavier-duty applications, vs the Tapcon anchor that typically serve lighter deployments. The anchor should be embedded to the minimum embedment depth recommended in data sheets available on the internet.Tapcon and wedge anchors are pre-installed mechanical anchors that attach structural objects to concrete structures. Strike the end of the anchor’s nut with a hammer to make sure that the attachment is firm. Tightly fix the nut and washer to the concrete’s surface. Use the hole in the fixture to insert the anchor’s clipped end and attach it to the concrete. Some measures need to be taken, which depend on the material of the surface being drilled. This video on using an anchor wedge will help you understand the process better. Make sure you have the drill bit of appropriate size before you proceed further. The drill bit size needed for a 3/8″ concrete wedge is 3/8th of an inch. You can install it on the concrete directly as well. Place the fixture on the anchor after installing it through a hole in the fixture.Thread a nut in a clockwise direction onto the anchor body to flush the top of the nut with the top of the anchor body to preserve the anchor’s thread during installation.Place one washer over the threaded end of the anchor body.The anchor wedge comes with the exact number of nuts and washers needed. Now that the hole is cleaned, you are ready to install the anchor wedge.Repeat this process multiple times to ensure that all the dirt has been removed. Use the wire brush to initially clean the hole and then use a vacuum cleaner.A vacuum cleaner or a wire brush can be used for cleaning the hole. Remove all dust and debris from the hole you have drilled, as this helps to enhance the holding value of the wedge anchor. ![]() Step 4: Clean The Hole And Install The EdgeĬlean the hole properly after it had been successfully drilled. The bit is retracted when it is in its most inward position inside the chuck of the drill.The bit should be in a retracted position when you set the depth gauge on the hammer drill or when you place the tap.You can also set a depth gauge on the hammer drill. Place a tape on the bit at the required depth to check the depth of the hole made.The minimum depth for a 3/8″ wedge anchor is one and a half inches. The minimum depth embedment for the anchor diameter must be met for the process to be completed seamlessly.Drill a hole in the concrete that is deeper than the minimum depth required.If you have doubts regarding the measurements, it is best to repeat the process. Step 3: Drill The Hole And Check Its DepthĪfter you have taken the necessary measurements, it is time to proceed with the actual drilling. This article has more information on wedge anchors. The minimum holding value will be determined by the hole tolerance and needs to be properly measured. This is needed to have an appropriate hole and anchor diameter. ANSI standard bits should be used to maintain proper hole tolerance.Chuck an ANSI standard carbide-tipped masonry bit into the hammer drill.The diameter of the bit must be the same as the anchor to be installed.To have more holding value, installing the wedge anchors at a much deeper depth than the minimum value calculated.The sum of the above two quantities determines the minimum length of the wedge anchor that is needed. Take the space required for nuts and washers into consideration. The sum of the thickness of the material to be attached and the diameter of the anchor to be installed needs to be calculated.
