The design of the Tapcon 174 concrete screw allows them to anchor into concrete and block Tapcon 174 concrete screws tap threads into a predrilled hole in concrete or block The 5 32 quot bit is used for the 3 16 quot Tapcon 174 concrete screw and the 3 16 quot bit is used for the 1 4 quot Tapcon 8 12 2021 nbsp 0183 32 Before a Tapcon masonry screw can be installed a hole must be drilled into the masonry Use a hammer drill to ensure that the hole has the proper tolerance The hammer motion breaks up the masonry material and the rotation removes the dust from the hole 11 7 2007 nbsp 0183 32 Short video on how to use tapcon concrete screws Purchase http www confast com products tapcon concretescrew aspx20 2 2009 nbsp 0183 32 Using a hammer drill we made quick work of the four holes which we drilled to a surface depth of 1 3 4″ This gave us enough depth for the Tapcon to mount flush into the piece of pressure treated wood and also sink a full 1 1 2″ into the concrete with an additional 1 4″ as recommended air gap after the end of the anchor 17 1 1999 nbsp 0183 32 Tapcon Concrete Screws Recently I went to use Tapcon screws to anchor some hangers to a concrete wall I used the 3 16″ by 1 25″ hex head screws in concrete the concrete is good quality and over 30 years old I ve used Tapcons in masonry before and no problems

28 10 2019 nbsp 0183 32 Using The Wrong Drill bit Size for The Fastener The hole needs to be slightly smaller than the diameter of the fastener so that the threads of the Tapcon have something to grab into If the masonry bit you use is too small you won t be able to drive the Tapcon in at all If the masonry bit is too large the Tapcon will not hold 24 5 2020 nbsp 0183 32 The Tapcon 174 concrete screw with the Climaseal 174 coating gives excellent rust resistance when used for indoor applications and outdoor applications The minimum embedment of a Tapcon 174 concrete screw is 1 and the maximum embedment is 1 3 4 The threads on the concrete screws are a maximum length of 1 3 4 Click to see full answer Use a twisting turning and up and down motion with the brush Vacuum the hole and repeat Compressed air can be used to clear the hole of all dust but this creates a lot of dust in the air and may not be suitable for all situations 5 Install the Tapcon Insert the screw through the fixture and into the predrilled hole in the concrete 18 2 2016 nbsp 0183 32 Tapcon screws with the washer are a very good choice if you might be moving things Make sure to use the correct size drill bit some boxes come with the right bit Don t over torque with the screw in the cement it will break or pull out as you have read 30 3 2006 nbsp 0183 32 I use a 18v Bosch hammer drill for that install what I like to do is put it in low range to drive the screw but still in hammer mode The effect is like a impact driver Here is some info on sizing if your using to long a screw it can be a problem Tapcon 175 Concrete Screw

Insert Tapcon concrete screw through hole in the fixture and into the hole in the base material Fasten the Tapcon concrete screw tight against the surface of the fixture being installed I use nut drivers and an impact drill to do this Ensure that the Tapcon concrete screw is not over torqued to avoid stripping the threads and to ensure 2 11 2018 nbsp 0183 32 If you have to attach something to concrete tap cons really work well And this video I go through the techniques I ve learned through the years and how to Builders commonly use Tapcon screws for concrete block and applications The threads in these screws hold firmly in all of these surfaces Inspect the Tapcon screw in the concrete to determine how deep it is impacted and check to see if the head of the screw is still in good shape Press firmly and turn the drill on 31 7 2009 nbsp 0183 32 This will provide the minimum and maximum length of screw that can be used Example A 2x4 needs to be fastened to concrete The 2x4 is 1 1 2 quot thick Adding the 1 1 2 quot of the 2x4 plus a minimum of 1 quot embedment 2 1 2 quot This 30 3 2020 nbsp 0183 32 Thereof how long should Tapcon screws be The maximum length would be 1 1 2 quot 1 3 4 quot 3 1 4 quot the maximum length of screw that can be used The proper length could be either the 2 3 4 quot or the 3 1 4 quot length concrete screw The 3 1 4 quot screw would be right at maximum embedment and depending on the abrasiveness of the base material may be too long

14 6 2020 nbsp 0183 32 Furthermore do I need to pre drill for Tapcon screws Before a Tapcon masonry screw can be installed a hole must be drilled into the masonry Use a hammer drill to ensure that the hole has the proper tolerance The carbide bit diameter required for the 3 16 screw is 5 32 For the 1 4 screw a 3 16 carbide tipped bit must be used Use metal lead anchors when drilling into masonry materials such as To insert screws into walls create holes with a hammer drill equipped with a masonry bit After lead anchors are inserted into the holes screw fasteners will slide into 24 11 2020 nbsp 0183 32 Tapcon 174 Concrete Screw Installation Steps 1 Using a hammer drill and a carbide tipped masonry bit meeting ANSI standards drill a hole the correct diameter required for the diameter of the screw that is being installed Make sure that the depth of the hole will be a minimum of 1 2 deeper than the Tapcon 174 concrete screw will penetrate 2 10 11 2021 nbsp 0183 32 The Tapcon 174 concrete screw with the Climaseal 174 coating gives excellent rust resistance when used for indoor applications and outdoor applications The threads on the concrete screws are a maximum length of 1 3 4 NOTE 3 16 Tapcon requires 5 32 bit 1 4 Tapcon requires 3 16 bit Allowable Edge and Spacing Distances Tapcon 174 Maxi Set Anchors PARAMETER ANCHOR DIA In mm NORMAL WEIGHT CONCRETE CONCRETE MASONRY UNITS CMU FULL CAPACITY Critical Distance Inches REDUCED CAPACITY Minimal Distance Inches LOAD REDUCTION
