About the Wedge Anchor Expansion Bolt
The wedge anchor is the default heavy-duty fixing into concrete: as the nut is tightened, the clip at the bottom is drawn up over the tapered stud and expands against the hole wall. It is a mechanical, load-bearing fixing rather than a friction plug, which is why it carries railings, machinery and racking.
Typical applications
- Structural and machinery fixing — Base plates, racking, conveyors and equipment anchored into concrete slabs.
- Railings and barriers — Handrails, guard rails and fence posts fixed to concrete or kerbs.
- Exterior and wet areas — Stainless 304 or 316 versions for facades, marine air and washdown areas.
How to choose the right specification
- Material by environment — Zinc plated for indoor dry use, SS304 for exterior, SS316 for coastal and chemical exposure.
- Diameter by load — M8–M10 for light fixtures and shelving, M12–M16 for railings and machinery, M20 for structural steel base plates.
- Length by embedment — The anchor must embed deep enough that the expansion clip sits fully in the concrete — and never in the bottom of the hole.
Supply, packing and OEM
Box or bulk carton, 1000 pcs per size per size, supplied assembled with nut and washer so the installer does not have to match parts on site. Thread length and clip geometry can be adjusted for your market's standards, DIN or ANSI.
Standard packing is box / bulk carton, minimum order 1000 pcs per size per size, with mixed sizes accepted on a first order. Bulk orders typically ship within 25–40 days after deposit, FOB Shanghai or Ningbo — about 2.5 hours from our workshop in Danyang.
Most of this item ships to Canada, Europe, Australia, Japan, the Middle East and South America. Tell us the destination market and we match the sizes, thread standard, marking and packing language it uses — metric for Europe, Japan and South America, imperial where the trade still buys in inches, and carton copy in the language your customers read — then quote FOB, CIF or DDP against your order size.
