Dewalt Anchors & Fasteners DFM1361350 CCU+ Heavy Duty Undercut Anchor 316 Stainless Steel (6/Box)
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. For exterior applications or where high corrosion resistance is required, the CCU+ is also available in ASTM A193 Grade 8BM, Class 2 high strength 316 stainless steel. CCU+ anchors are installed into a fixed depth hole with a cone-shaped cavity at the bottom which is created in a secondary drilling operation using a specialty undercut drill bit supplied by DEWALT. The result is bottom-bearing post-installed anchor which keys into the base material with minimal expansive forces allowing for close edge distance and anchor spacing, similar to a cast-in-place headed stud. The heavy-wall expansion sleeve contributes to load transfer and improved shear capacities particularly for the thrubolt version.
Features
- 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
- Thrubolt 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
- DEWALT dust removal drilling system (with HEPA dust extractor) can be used for an OSHA 1926.1153 Table 1 compliant solution
- CCU+ undercut anchors made in USA at time of publication; product certifications available by request (anchors@DEWALT.com)
