Drop In Anchors - Reliable, Versatile and Long Lasting
Drop-in anchors are deformation-controlled expansion anchors designed for attaching various decorations, utility or construction elements to a solid base material such as concrete or masonry. This anchor is composed of a hollow sleeve and an internal expander plug as shown in the following picture:
Four equally spaced slots are cut longitudinally up from one end of the hollow sleeves to form expandable shirts.
Internal expander plugs are inside the hollow sleeves for forcing the anchors to expand and be locked in place.
- A hollow sleeve
- Four equally spaced slots cut longitudinally to create an expandable shirt at one end.
- With internal threads at the other end of the sleeve to accept a bolt or a threaded rod easily.
- Special patterns for higher holding strength as it increases more friction between the anchor and drilled holes.
- An internal expander plug
Located inside the sleeve above the slots, this solid, cone-shaped plug is gone through case hardening and tempering to avoid galling and binding during expansion effectively. It works by forcing the expandable shirt outward for locking the anchor in place.
- Qualified - Shunfeng adopts high quality carbon or stainless steel 304, 316 as the material.
- Internal threaded - Allowing hardware like hex bolts and threaded rods to be mounted & removed easily, leaving the drop-in anchor in place.
- Versatile - Whether it be medium or heavy-duty application, our range of drop-in anchor is the best solution.
- Long lasting - Our range of drop-in anchor is zinc-plated for a longer lifespan by discouraging corrosion.
- Easy to install - Just drop the anchor into the pre-drilled suitable sized hole, and then use a setting tool to expand the anchor.
Drop-in anchors perform well in fastening the lights to the concrete ceiling.
Drop-in anchors can be used to fasten a variety of objects such as
- Fire sprinkler pipes.
- Flower pots.
- Hanger brackets.
- Cable trays.
- Window box.
- Suspending grids.

Drill a suitable sized hole slightly deeper than the length of your drop-in anchors. Use a vacuum cleaner to remove the debris from the hole.
Push your drop-in anchor to the bottom of the hole. A hammer can also be used for easy tapping if necessary.
Use a setting tool to drive the internal expander plug to the bottom and force the tabs between slots outward. The anchor is properly expanded when the shoulder of the setting tool touches the face of the anchor.
Screw a bolt or a threaded rod to the anchor, attaching the things required to be fastened to the solid base material as shown in the left picture.
