SIMPSON STRONG-TIE DIA25 DROP-IN ANCHOR 1/4

Drop-In Internally Threaded Expansion Shell Anchor

Drop-in anchors are internally threaded drop-in expansion anchors for use in flush-mount applications in solid base materials.

Features:

·         Lip at the top of the anchor body keeps the top of the anchor flush with the concrete

·         Available in coil-threaded versions for ½" and ¾" coil-threaded rod

·         Eliminates the need for precisely drilled hole depths and enables an easier flush installation, consistent embedment and uniform rod lengths

·         Minimum thread engagement should be equal to the nominal diameter of the threaded insert

Codes: Drop-In: City of L.A. RR24682; Factory Mutual 3017082; Underwriters Laboratories File Ex3605. The product meets requirements of Federal Specifications A-A-55614, Type I. Short Drop-In: Factory Mutual 3017082 & Underwriters Laboratories File Ex3605.

Material: Carbon and stainless steel (DIA37S available in zinc-plated, carbon steel only)

Finish: Carbon steel: Zinc plated

Installation:

·         Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the Drop-In Anchor Setting Tool Product Data table.

·         Drill the hole to the specified embedment depth plus 1/8" for flush mounting.

·         Blow the hole clean using compressed air. Overhead installations need not be blown clean.

Caution: Oversized holes will make it difficult to set the anchor and will reduce the anchor’s load capacity

·         Insert designated anchor into hole. Tap with hammer until flush against surface.

·         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.

For additional suggested specifications, please see the Anchoring and Fastening Systems for Concrete and Masonry catalog.

Short Drop-In

Drop-in anchors are internally threaded, deformation-controlled expansion anchors with a pre-assembled expander plug, suitable for flush mounting in solid base materials. A ½" diameter Short Drop-In anchor complements the existing 3/8" diameter offering for solid and hollow concrete applications.

Features:

·         Short length enables shallow embedment that helps avoid drilling into rebar or pre-stressedor post-tensioned cables.

·         Lipped edge enables consistent embedment that contributes to uniform rod lengths and installation into deep and bottomless holes

·         Lipped edge eliminates the need for precisely drilled hole depths

·         Each box includes a setting tool compatible with the anchor to ensure consistent installation

Material: Carbon steel

Finish: Zinc plated
