DESCRIPTION/SUGGESTED SPECIFICATIONSDrop-In, Shell-Type Anchors—Multi-Set II Drop-In AnchorsInternallyThreaded HeavyDuty AnchoringSystemsSPECIFIED FOR ANCHORAGE INTO CONCRETEDrop-In, shell-type anchors feature an internally threaded, all-steel shell with expansion cone insertand flush embedment lip. Anchors are manufactured from zinc-plated carbon steel, 18-8 stainless steel and316 stainless steel.Anchors should be installed with carbide tipped hammer drill bits madein accordance to ANSI B212.15-1994 specifications.The minimum concrete thickness for an anchor is 1-1/2 times theembedment depth – or the embedment depth plus three times the anchordiameter – whichever is greater.Multi-Set II Drop-In AnchorsAnchors should be tested to ASTM E488 criteria.ADVANTAGESShort Drop-In (RX) AnchorsRM Drop-In AnchorIdeal for Hollow-Core, Pre-Cast Plankand Post Tension Slabsn Lipped anchor body k eepsanchor flushn Easy installationn Keeps all rods same lengthn Easy inspectionTMn Available in carbon steel,18-8 and 316 stainless steelRL Drop-In Anchorn Below surface settingfor easy patch workn Optimized for use in hollowcore, pre-cast plank and posttension slabsn L ip keeps anchor flushduring installationn S hallow drilling—fastinstallationCoil Thread AnchorRX Drop-InAnchorn Quick thread attachment—ideal for 1 sided formingn Use coil rod on jobn 2 diameters (1/2” and 3/4”)80Call our toll free number 800-848-5611 or visit our web site for the mostcurrent product and technical information at www.itwredhead.com

Specification A-A-55614 Type 1(Formerly GSA: FF-S-325 Group VIII)Multi-Set II Drop-in anchors may be covered by one or more of thefollowing approvals/listings: Underwriters Laboratories Factory Mutual CaltransSee Selection Chart next page.INSTALLATION STEPSTo set anchor flush with surface:The Multi-Set Anchor is the standardfor pipe-hanging. The RM version has aretainer lip to keep all anchors flush atthe surface, keeping all your threadedrod the same length.1. Drill hole to required embedment(see Table on page 82).2. Clean hole with pressurized air.FEATURESExpander Slots—allow for easy settingand superior performance3. Drive anchor flush with surface of concrete.Cone Insert—that expands the anchorwhen driven with setting tool and hammerBody—available in zinc-plated steel,18-8 stainless steel, and 316 stainless steel4. Expand anchor with setting tool provided(see chart on page 82). Anchor is properlyexpanded when shoulder of setting tool is flushwith top of anchor.Easy Depth Inspection—keeps threadedrod drop lengths consistentRetainer Lip—to keep anchor flushwith surfaceFor use with threaded rods or headedbolts (supplied by contractor)SELECTION CHARTTMBits for RX-38 and RX-12Short Drop-InsBIT NO.DESCRIPTIONDRILLINGDEPTHDCX-1383/8" Depth Charge Stop Drill (RX-38)3/4"DCX-1121/2" Depth Charge Stop Drill (RX-12)1"Call our toll free number 800-848-5611 or visit our web site for the mostcurrent product and technical information at www.itwredhead.comn S houlder prevents over drilling.

The mass ‘m’of the oil drop is given by: m (4/3)πa3σ (4) where ‘a’ is the radius of the drop and ‘σ’ is the density of the oil drop. To calculate the radius of the oil drop you will need to use Stokes’ Law, which relates the radius of a spherical falling body in a viscous medium to its terminal velocity. According
