1 General Information GENERAL INFORMATION ATOMIC+ UNDERCUT Heavy Duty Undercut PRODUCT DESCRIPTION The Atomic+ Undercut anchor is designed for applications in cracked and uncracked concrete. The anchors are is available in standard ASTM A 3 steel, high strength ASTM A 193 Grade B7 steel and Type 31 stainless steel in Class 1 and Class 2 strength designations. The Type 31 stainless steel version can be considered for exterior use and industrial applications where a high level of corrosion resistance is required. The Atomic+ Undercut anchor is installed into a predrilled hole which has been enlarged at the bottom in the shape of a reversed cone using the undercut drill bit supplied by DEWALT. The result is an anchor which transfers load mainly through bearing, and unlike a typical expansion anchor is not dependent upon friction between the expansion sleeve and the concrete. Due to the use of a thick walled expansion sleeve, the load is distributed to a large area which can provide ductile behavior of the anchor even at relatively shallow embedments.

3 Installation Instructions INSTALLATION INSTRUCTIONS Installation Instructions for Atomic+ Undercut s 1. Using the proper drill bit size, drill a hole into the base material to the required depth. The tolerances of the drill bit used should meet the requirements of ANSI Standard B remove dust and debris from the hole during drilling (e.g. dust extractor, hollow bit) or following drilling (e.g. suction, forced air) to extract loose particles created by drilling. 3. Insert the undercut bit and start the rotohammer. Undercutting is complete when the stopper sleeve is fully compressed (gap closed). remove dust and debris from the hole following drilling (e.g. suction, forced air). Insert anchor into hole. Place setting sleeve over anchor and drive the expansion sleeve over the expansion coupling.. Verify that the setting mark is visible on the theaded rod above the sleeve.

6 Performance Data Mechanical s FACTORED DESIGN STRENGTH (fnn AND fvn) CALCULATED IN ACCORDANCE WITH ACI 311 CHAPTER 17: 1 Tabular values are provided for illustration and are applicable for single anchors installed in normalweight concrete with minimum slab thickness, ha = hmin2, and with the following conditions: ca1 is greater than or equal to the critical edge distance, cac (table values based on ca1 = cac). ca2 is greater than or equal to 1. times ca1. 2 Calculations were performed according to ACI 311 Chapter 17. The load level corresponding to the controlling failure mode is listed. (e.g. For tension: steel, concrete breakout and pullout; For shear: steel, concrete breakout and pryout). Furthermore, the capacities for concrete breakout strength in tension and pryout strength in shear are calculated using the effective embedment values, hef, for the selected anchors as noted in the design information tables. Please also reference the installation specifications for more information. 3 Strength reduction factors (ø) were based on ACI 311 Section.3 for load combinations. Condition B is assumed. Tabular values are permitted for static loads only, seismic loading is not considered with these tables. For designs that include combined tension and shear, the interaction of tension and shear loads must be calculated in accordance with ACI 311 Chapter 17. Interpolation is not permitted to be used with the tabular values. For intermediate base material compressive strengths please see ACI 311 Chapter 17. For other design conditions including seismic considerations please see ACI 311 Chapter 17.

8 Performance Data Mechanical s FACTORED DESIGN STRENGTH (fnn AND fvn) CALCULATED IN ACCORDANCE WITH ACI 311 CHAPTER 17: 1 Tabular values are provided for illustration and are applicable for single anchors installed in normalweight concrete with minimum slab thickness, ha = hmin2, and with the following conditions: ca1 is greater than or equal to the critical edge distance, cac (table values based on ca1 = cac). ca2 is greater than or equal to 1. times ca1. 2 Calculations were performed according to ACI 311 Chapter 17. The load level corresponding to the controlling failure mode is listed. (e.g. For tension: steel, concrete breakout and pullout; For shear: steel, concrete breakout and pryout). Furthermore, the capacities for concrete breakout strength in tension and pryout strength in shear are calculated using the effective embedment values, hef, for the selected anchors as noted in the design information tables. Please also reference the installation specifications for more information. 3 Strength reduction factors (ø) were based on ACI 311 Section.3 for load combinations. Condition B is assumed. Tabular values are permitted for static loads only, seismic loading is not considered with these tables. For designs that include combined tension and shear, the interaction of tension and shear loads must be calculated in accordance with ACI 311 Chapter 17. Interpolation is not permitted to be used with the tabular values. For intermediate base material compressive strengths please see ACI 311 Chapter 17. For other design conditions including seismic considerations please see ACI 311 Chapter 17.
