🔹 What is the difference between a sinco anchor bolt sleeve and a standard drop-in anchor?

A sinco anchor bolt sleeve uses a one-piece internally threaded sleeve that expands uniformly against the concrete wall — providing 30% higher pull-out resistance compared to thin-walled drop-in anchors. Ideal for dynamic loads and seismic zones.
