GENERAL INFORMATION

SMART DI™
Internally threaded expansion anchor

PRODUCT DESCRIPTION
The smart DI is an all-steel, machine bolt anchor available in carbon steel. It can be used in solid concrete, hard stone, and solid block base materials. The smart DI is specifically designed to be easier to fully set into the base material during installation as a benefit to the user.

GENERAL APPLICATIONS AND USES

• suspending Conduit
• Fire sprinkler
• Cable Trays and strut
• Concrete Formwork
• Pipe supports
• suspended Lighting

FEATURES AND BENEFITS

• Installs with reduced effort compared to traditional drop-in style anchors
• Can be installed using the manual setting tool or smart DI system with a hammer-drill
• setting indicator makes identification of properly set anchors easy (when installed using the smart tool and smart bit)
• Internally threaded anchor for easy bolt removability and service work

TESTING, APPROVALS AND LISTINGS

• FM Global (Factory Mutual) – File No. 3059197 (3/8″ and 1/2″ diameters)
• Underwriters Laboratory (UL Listed) – File No. EX1289 (N) (3/8″ and 1/2″ diameters)

INSTALLATION INSTRUCTIONS

Manual Installation

1. Using the proper drill bit size, drill a hole into the base material to the depth of embedment required. The tolerances of the drill bit used must meet the requirements of  ANSI standard B212.15. Use any ANSI standard carbide drill bit.

2. 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. Insert the anchor into the hole and, if necessary tap flush with the surface.

3. Using a DEWALT manual setting tool specifically, set the anchor by driving the tool with a sufficient number of hammer blows until the shoulder of the tool is seated against the anchor. The anchor will not hold the allowable loads required if the shoulder of the DEWALT manual setting tool does not seat against the anchor. Proper manual installation may not remove blue indicator paint.

4. If using a fixture, position it, insert the bolt and tighten so as not to exceed the maximum tightening torque. Most overhead applications utilize threaded rods. Minimum thread engagement should be at least one anchor diameter.

Smart DI System Installation

1. Using the proper drill bit size, drill a hole into the base material to the depth of embedment required using the appropriate DEWALT DI stop Drill Bit. The tolerances of the drill bit used must meet the requirements of ANSI standard B212.15. standard installation with a DI stop Drill Bit may result in the anchor being slightly subset from the surface.
   Minimum published embedment depths must be achieved by using the shoulder of the DI stop Drill Bit as a guide.

2. 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. Insert the anchor into the hole and, if necessary, tap flush with the surface.

3. slide the appropriate DEWALT DI setting Tool over the DI stop Drill Bit used to drill the hole and twist counterclockwise to lock the setting tool onto the bit. If the tool does not fit snug onto the bit it may be necessary to replace the internal rubber spring plug in the tool (see ordering information). replacement kit sold separately.

4. once attached, insert the tip of the setting tool into the smart DI anchor and drive the internal plug fully using the rotation with hammer mode of the sDs+ drill (see table below for suggested tools).

5. For proper installation, the shoulder of the setting tool must come briefly in full contact with the smart DI resulting in the blue indicator paint being removed from the raised top of the anchor. The paint will remain in the recessed portion of the top indicating full expansion.

6. If using a fixture, position it, insert the bolt and tighten so as not to exceed the maximum tightening torque. Most overhead applications utilize threaded rods. Minimum thread engagement should be at least one anchor diameter.

1. Tabula ed load values are for anchors ins ailed in uncracked concrete. Concrete compressive strength must be at the specified minimum at the time o installation.
2. Ultimate load capacities must be reduced by a minimum safety factor of 4.0 or greater to determine allowable working load. The allowable load capacities listed are calculated using and applied
a safety factor of 4.0.
3. Allowable loads for lightweight concrete may be determined by multiplying the tabulated allowable load capacities for normal-weight concrete by 0.60.
4. Linear interpolation may be used to determine allowable loads for intermediate compressive strengths.
5. The tabulated capacities are for the steel drop-in anchors which must be checked against the steel strength of the corresponding threaded rod or bolt size and type, the lowest load level controls.

DESIGN CRITERIA (ALLOWABLE STRESS DESIGN)

Combined Loading
For anchors loaded in both shear and tension, the combination of loads should be proportioned as follows:

Load Adjustment Factors for Spacing and Edge Distances
Note: Allowable load values found in the performance data tables are multiplied by reduction factors when anchor spacing or edge distances are less than critical distances.
Linear interpolation is allowed for intermediate anchor spacing and edge distances between critical and minimum distances. When an anchor is affected by both reduced spacing and edge distance, the spacing and edge reduction factors must be combined (multiplied). Multiple reduction factors for anchor spacing and edge distance may be required depending on the anchor group configuration.
