DeWalt DW5366 UltraCon Tapcon Installation Kit: A Purpose-Built Way to Set Concrete Fasteners

Introduction

Setting concrete fasteners all day is a different job from occasionally drilling a hole in masonry. The DeWalt DW5366 UltraCon Tapcon Installation Kit is built around that reality. It is designed to pair with DeWalt’s 12V Max Extreme rotary hammer and takes the guesswork out of drilling the hole and driving the screw to the right torque. If your work involves anchoring into concrete block, brick, or similar materials, this kit deserves a close look.

What’s in the Kit

The UltraCon kit ships in a sturdy plastic case and is an SDS Plus system made to set both hex and Phillips fasteners. The case is more than just storage: it can hold the UltraCon bits and accessories as well as a supply of fasteners, and you can reorganize the compartments depending on the size of screws you are carrying. That makes it a genuinely portable solution. The whole kit is light enough to drop into a pouch or apron, though if you are working up high you will want to lanyard it somehow.

Product number DW5366, it is purpose built for rotary hammers rather than adapted from a general-purpose accessory set, and that focus shows in how the system works.

How the Kit Works

The workflow is straightforward. First, choose the correct drill bit size for your fastener, following the fastener manufacturer’s recommendations. Insert the rotary hammer bit into the tool, then set the depth guide slightly deeper than the hole you need. A useful habit is to hold the Tapcon up against the depth gauge and make the setting a little deeper than required, then tighten the gauge down and drill.

After drilling, clear the dust from the hole so it does not fall back in and compromise the anchor. Pulling the bit back evacuates the debris before you set the fastener.

Who This Kit Is For

This is not a kit for drilling oversized holes. It is aimed squarely at technicians, electricians, and plumbers who set Unistrut and Tapcon fasteners all day long: drill the hole, set the screw, repeat. For that crowd, having the bits, drive sleeve, nut setters, and the fasteners themselves organized in one compact case is a real productivity gain.

Why the Hex Boss Matters

One detail to understand before buying: you cannot use just any bits with this system. The bits must have a hex shank or boss on them. DeWalt’s own bits include it, and other brands such as Diablo also make bits in this style. The boss is what allows the UltraCon drive sleeve to slide down over the drill bit.

The reason this matters is torque control. If you over-torque a concrete fastener, one of two things happens: the fastener snaps, or the concrete blows out. DeWalt’s UltraCon drive takes that risk out of the process. Depending on the fastener, you can sometimes drive with the sleeve itself, and if that does not suit the screw, the kit includes multiple nut setters that fit into the end of the sleeve.

The drive is also magnetic, so the fastener stays in place whether you are driving up, out, or down at an awkward angle. There is no fumbling with a separate impact driver, no dropped screws, and no switching between drilling and driving setups. In practice that makes the job faster and safer, and over a full day of anchor installation it adds up to real productivity.

Buying Advice

If you already own a compatible rotary hammer and regularly set concrete fasteners, this kit is an easy recommendation: it consolidates the whole drill-and-drive workflow into one case and one system. If you only have a regular hammer drill rather than a rotary hammer, DeWalt also offers a variant of this installation approach for hammer drills, so you are not locked out if that is the tool you own.

Before buying, confirm your fastener sizes and pick the appropriate bit sizes based on the fastener manufacturer’s recommendations, since bit selection depends on the screws you use.

Conclusion

The DeWalt DW5366 UltraCon kit solves a specific problem well: setting Tapcon-style concrete fasteners quickly, consistently, and at the right torque. For anyone who spends their workday anchoring into block and brick, the combination of a purpose-built drive system, magnetic fastener retention, and a portable, reorganizable case makes it a practical upgrade over improvising with an impact driver.
