CCU+™ Undercut Mechanical Anchors

The DEWALT Critical Connection Undercut (CCU+™) anchor is a post-installed structural anchor designed for static, dynamic and seismic loading in the tension zone of both cracked and uncracked concrete. The high capacity CCU+™ anchor can be loaded immediately following installation and is available in zinc plated ASTM A36 (F1554 Grade 36) mild carbon steel and ASTM A193 Grade B7 high strength carbon steel.

Critical Connection Undercut Anchors are High Corrosion Resistance

General Applications and Uses

Structural connections (e.g. beam, column)
Safety related fastening and assemblies
Bridge, tunnel and port structure attachments
Water and wastewater treatment facility units
Vessel, tank and containment wall anchorage
Power generation plant / hydro dam anchors
Industrial machine and equipment mounts
Utility system bracing, hangers and supports
Barriers, guards, fencing and railing
Retrofit anchors for cast-in anchor bolts
Tension zone / cracked concrete
Seismic attachments (SDC A - F)cations

Features and Benefits

Load transfers to concrete through bearing not friction (similar to cast-in headed bolts)
Provides positive mechanical interlock into base material +Consistent predictable behavior and exceptional load capacities
Robust design minimizes anchor displacement under load
Anchor bearing area is more than two-and-a-half times the net tensile area of the anchor rod
Anchor rods can be designed for stretch length and ductile steel behavior for seismic loading
Close edge distance, anchor spacing, and slab thickness due to low expansive forces
Thru bolt version provides significant increase in shear capacities and variable fixture thickness
Length ID code and material ID marking stamped on head of each anchor
Undercut cavity is created in seconds with durable undercutting tool

THREADED VERSION
UNC threaded stud (anchor rod)

ANCHOR MATERIALS

Zinc Plated Carbon steel
316 stainless steel

ANCHOR SIZE RANGE (TYP.)
3/8” through 3/4" diameters (anchor rod diameter)

SUITABLE BASE MATERIALS

Normal-weight concrete
Lightweight concrete
