MECHANICAL ANCHORS > Drop-in Anchor 

Internally Threaded Expansion Shell Anchor

Drop-in  Lipped Drop-in  Standard Setting Tool  Drop-in Test

Drop-in anchors are internally threaded, deformation controlled expansion anchors with a preassembled expander plug, suitable for flush mount applications in solid base materials. The anchor is set by driving the expansion plug towards the bottom of the anchor using the setting tool. The Lipped Drop-In (DIAL) features a lip at the top of the anchor body that keeps the top of the anchor flush with the concrete. This eliminates the need for precisely drilled hole depths and allows for easier flush installation, consistent embedment and uniform rod lengths.

Material:

Carbon and A4 Stainless steel (DIAL1030 available in zinc plated carbon steel only)

Finish:

Zinc plated carbon steel and A4 Stainless steel

Test Criteria:

The Drop-In anchor has been tested in accordance with ASTM E488 Standard Test Methods for Strength of Anchors in Concrete and Masonry Elements.

Installation:

Drill a hole in the base material using the proper diameter carbide drill bitas specifi ed in the table. Drill the hole to the specifi ed embedment depthplus 3 to 5mm for flush mounting. Blow the hole clean using compressedair. Overhead holes do not need to be blown clean.

Note CAUTION- oversize holes will make it diffi cult to set the anchor and will reduce the anchor’s load capacity.

  • Insert anchor into hole. Tap with hammer until fl ush against the surface. 
  • Using the proper sized Drop-In setting tool (DIAST); drive the expander plug towards the bottom of the anchor until shoulder of setting tool makes contact with the top of the anchor.

Tension and Shear Loads for Metric Drop-In (Carbon and Stainless Steel) and Metric Lipped Drop-In (Carbon Steel) Anchors Installed in Normal-Weight Concrete

Tension and Shear Loads for Metric Drop-In

  1. The allowable loads listed are based on a safety factor of 4.0. 
  2. Allowable loads may not be increased for short-term loading due to wind or seismic forces. 
  3. Refer to allowable load adjustment factors for edge distance and spacing. 
  4. The minimum concrete thickness is 1.5 x times the embedment depth. 
  5. Loads are for carbon steel DIAL 1030 Lipped Drop-In only. 
  6. Drill the hole to the specifi ed embedment depth plus 3 to 5mm for fl ush mounting. 

Load-Adjustment Factors for Drop-In (Carbon and Stainless Steel) and Lipped Drop-In (Carbon Steel) Anchors in Normal-Weight Concrete: Edge Distance and Spacing, Tension and Shear Loads

How to use these charts:

  1. The following tables are for reduced edge distance and spacing. 
  2. Locate the anchor size to be used for either a tension and/or shear load application. 
  3. Locate the edge distance (Cact) or spacing (Sact) at which the anchor is to be installed. 
  4. The load adjustment factor (fc or fs) is the intersection of the row and column. 
  5. Multiply the allowable load by the applicable load adjustment factor. 
  6. Reduction factors for multiple edges or spacing are multiplied together. 

Edge Distance Tension

* See Notes Below

Spacing Tension and Shear

  1. E = Embedment depth (mm). 
  2. Sact = actual spacing distance at which anchors are installed (mm). 
  3. Scr = critical spacing distance for 100% load (mm). 
  4. Smin = minimum spacing distance for reduced load (mm). 
  5. fs = adjustment factor for allowable load at actual spacing distance. 
  6. fscr = adjustment factor for allowable load at critical spacing distance. fscr is always = 1.00. 
  7. fsmin = adjustment factor for allowable load at minimum spacing distance. 
  8. fs = fsmin + [(1 - fsmin) (Sact - Smin) / (Scr - Smin)]. 
  9. M10 DIAL1030 Lipped drop-in anchor. 

Edge Distance Shear

  1. Cact = actual edge distance at which anchor is installed (mm). 
  2. Ccr = critical edge distance for 100% load (mm). 
  3. Cmin = minimum edge distance for reduced load (mm). 
  4. fc = adjustment factor for allowable load at actual edge distance. 
  5. fccr = adjustment factor for allowable load at critical edge distance. fccr is always = 1.00. 
  6. fcmin = adjustment factor for allowable load at minimum edge distance. 
  7. fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
