Drop-In Internally Threaded Anchor (DIAB) Expansion shell anchors for use in solid base materials Simpson Strong-Tie introduces a new, redesigned Drop-In Anchor (DIAB) that provides easier installation into base materials. Improved geometry in the preassembled expansion plug improves setting capability so the anchor installs with 0% fewer hammer strikes than previous versions. These displacement-controlled expansion anchors are easily set by driving the plug toward the bottom of the anchor using either the hand- or power-setting tools. DIAB anchors feature a positive-set marking indicator at the top of the anchor helping you see more clearly when proper installation has taken place. Use a Simpson Strong-Tie fixed-depth stop bit to take the guesswork out of drilling to the correct depth. The fluted design of the tip draws debris away from the hole during drilling, allowing for a cleaner installation. Key features New design offers easier installation then previous drop-in anchor design sets with 0% fewer hammer hits Positive-set marking system indicates when anchor is properly set Lipped drop-in version available for flush installation Hand- and power-setting tools available for fast, easy and economical installation Fixed-depth stop bit helps you drill to the correct depth every time Anchor being set with hand setting tool. Material: Carbon steel Coating: Zinc plated Anchor being set with SDS setting tool. Drop-In Lipped Drop-In Positive set indicator.

Drop-In Internally Threaded Anchor (DIAB) DIAB Manual Installation Caution: Oversized holes will reduce the anchors load capacity 1. Drill a hole in the base material using the appropriate diameter carbide drill bit or fixed depth bit as specified in the table. Drill the hole to the specified embedment. For fixed depth bits drill the hole until the shoulder of the bit contacts the surface of the base material. Then blow the hole clean of dust and debris using compressed air. Overhead installations need not be blown clean.. Insert the anchor into the hole. Tap with hammer until flush against the surface. 3. Using the designated Drop-In setting tool, drive expander plug towards the bottom of the anchor until the shoulder of the setting tool makes contact with the top of the anchor. When properly set indentations will be visible on the top of the anchor indicating full expansion.. Insert bolt or threaded rod. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.!! DIAB SDS Installation Caution: Oversized holes will reduce the anchors load capacity 1. Drill a hole in the base material using the appropriate diameter carbide drill bit or fixed depth drill bit as specified in the table. Drill the hole to the specified embedment. For fixed depth bits drill the hole until the shoulder of the bit contacts the surface of the base material. Then blow the hole clean of dust and debris using compressed air.

Drop-In Internally Threaded Anchor (DIA) Drop-in anchors are internally threaded drop-in expansion anchors for use in flush-mount applications in solid base materials. Available in stainless steel (DIA), short (DIAS) or coil-thread (DIAC) versions. Minimum thread engagement should be equal to the nominal diameter of the threaded insert. Features Lipped edge (DIAS) eliminates need for precisely drilled hole depth Available in coil-thread version for ½" and ¾" coil-threaded rod Short length (DIAS) enables shallow embedment to help avoid drilling into rebar or pre-stressed/post-tensioned cables Short Drop-In anchors include a setting tool compatible with the anchor to ensure consistent installation Material: Carbon and stainless steel Coating: Carbon steel; zinc plated Codes: Drop-in: DOT; Factory Mutual 30170; Underwriters Laboratories File Ex305. Meets requirements of Federal Specifications A-A-551, Type I. Short drop-in: Factory Mutual 30170 and Underwriters Laboratories File Ex305. Caution: The load tables list values based upon results from the most recent testing and may not reflect those in current code reports. Where code jurisdictions apply, consult the current reports for applicable load values. Drop-In Stainless Steel Short Drop-In Installation 1. Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the table. Drill the hole to the specified embedment depth plus " for flush mounting. Blow the hole clean using compressed air. Overhead installations need not be blown clean.. Insert designated anchor into hole. Tap with hammer until flush against surface. 3. Using the designated drop-in setting tool, drive expander plug toward the bottom of the anchor until shoulder of setting tool makes contact with the top of the anchor.. Minimum thread engagement should be equal to the nominal diameter of the threaded insert. Caution: Oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity.

Drop-In (DIA) Design Information Concrete Load-Adjustment Factors for Short Drop-in Anchors in Sand-Lightweight Concrete over Metal Deck: Distance and, Tension and Shear Loads How to use these charts: 1. The following tables are for reduced edge distance and spacing.. Locate the anchor size to be used for either a tension and/or shear load application. 3. Locate the edge distance (c act ) or spacing (s act ) at which the anchor is to be installed.. The load adjustment factor (f c or f s ) is the intersection of the row and column. 5. Multiply the allowable load by the applicable load adjustment factor.. Reduction factors for multiple edges or spacing are multiplied together.
