HDIA25 Hollow Drop-In Anchor (Pack of 100pcs)
The Simpson Strong-Tie Hollow Drop-In Anchor (HDIA) is an internally threaded, flush-mount expansion anchor for use in hollow materials such as CMU and hollow-core plank, as well as in solid base materials such as brick, normal-weight and lightweight concrete.
Key Features:
Suitable for suspending conduit, cable trays, pipe supports, fire sprinklers and suspended lighting into concrete
Expansion design allows HDIA to anchor into CMU, hollow-core plank, brick, normal-weight concrete and lightweight concrete
Internally threaded anchor allows for easy bolt removal
Material:
Die-cast Zamac 3 alloy shell with carbon-steel cone or 304 stainless-steel cone
Installation:
Installation Instructions — Solid Base (using solid setting tool)
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.
Blow the hole clean using compressed air. Overhead installations need not be blown clean.
Insert the HDIA into hole. Tap with hammer until flush against surface.
Using the designated setting tool, drive the anchor to the bottom of the drilled hole. After the anchor reaches the bottom of the drilled hole, perform an additional three hammer blows against the setting tool to drive the anchor body over the cone.
Position fixture; insert fastener and tighten.
Installation Instructions — Hollow Base (using hollow setting tool)
Drill a hole in the base material using the appropriate diameter carbide drill bit as specified in the table.
Thread the HDIA onto the designated setting tool for hollow base materials.
Insert the HDIA into the hole. Tap the setting tool until the face of the tool contacts the surface.
Rotate the setting tool a minimum of two turns to set the anchor.
