Wedge anchor is a heavy‑duty mechanical expansion anchor for solid concrete and dense masonry. When tightening the nut, the wedge cone pushes the split expansion sleeve to expand outward, generating strong friction grip against hole wall. It is supplied complete with nut and washer. Material: carbon steel (grade 4.8 / 8.8 / 10.9), stainless steel 304 / 316. Finishes: blue‑white zinc plated, color zinc plated, hot‑dip galvanized, natural passivation. Widely used for fixing steel brackets, machinery, handrails, facade panels and heavy‑load equipment on solid concrete substrate.
