The hole must also be drilled into the base material a minimum of 1/2” deeper than the screw will penetrate the base material. The 3/16” diameter concrete screws require a 5/32” hole and the 1/4” diameter require a 3/16” hole diameter. When installing a concrete screw it is very important to use the correct bit size because the hole size and screw size tolerance are critical.

The 3/16” diameter screw requires a 1/4” driver and the 1/4” diameter requires a 5/16” driver. This might be a consideration when choosing the most appropriate fastener. The head size on the 3/16” diameter Tapcon® is smaller than on the 1/4”.

The screw length that is used most frequently for this application is the 1-1/4” and the 1-3/4”, either in the 3/16” diameter or the 1/4” diameter. The Tapcon concrete screw requires a minimum embedment depth of 1” and a maximum embedment depth of 1-3/4”. Tapcons are easily removed if needed and have excellent holding values both in the 3/16” diameter and the 1/4” diameter head style. The hex head anchor works best because of its positive drive when installing and the smaller head does not protrude into the junction box. They are the most versatile type of concrete fastener for this type of application because they work equally well regardless of the material, have consistent holding values and have a high installation success rate. Tapcon® concrete screws are commonly used for fastening a junction box to concrete, brick or block base material. Most electrical junction box applications require that the concrete fastener does not protrude into the box and have a finished or smaller head to allow more space in the junction box as well as to eliminate a snag point for the electrical wires.

Different types of anchors are available, the anchor chosen will depend on the specific application and user preference. Electrical junction boxes need to be attached to a variety of base materials such as concrete, brick or block. Boxes that measure 2” x 3” x 2-1/2” typically have three wires, while the boxes that measure 2” x 3” x 3-1/2” usually have 5 wires. The most common junction boxes measure 2-1/2” to 3-1/2” deep and are used according to the number of wires being joined together. Electrical junction boxes are metal or plastic enclosures in which electric wires meet and join together.
