Qi Sheng drop in anchors are internally threaded anchors designed for installation in concrete, commonly used when a flush surface finish is preferred. They are widely applied for overhead installations, suspended systems, and general concrete anchoring where a clean, internal-thread connection is needed.
We can supply drop in anchors in multiple diameters and lengths, with material and finish options selected for jobsite conditions and corrosion-resistance requirements. Bulk orders and OEM packaging can be supported for B2B buyers.
