Stainless Steel Wedge Anchors
What are stainless steel wedge anchors? Stainless steel wedge anchors are stud-type expansion anchors for solid concrete that lock in place as a clip expands against the hole when the nut is tightened. Made from 304 and 316 stainless, they deliver some of the highest holding values available while resisting rust in wet, coastal, and outdoor use.
When to choose a wedge anchor over other concrete anchors
Wedge anchors give the highest holding values of the common mechanical anchors and are the go-to for heavy, load-bearing fastening into solid, cured concrete. They are not for hollow block or brick, where a sleeve anchor is the better fit. Choose stainless when the anchor point is exposed to moisture or weather, and step up from 304 to 316 for coastal and saltwater sites.
Why choose stainless steel wedge anchors
- High holding strength: among the strongest mechanical anchors for solid concrete.
- Corrosion resistance: 304 and 316 keep holding power in wet and coastal conditions.
- Permanent set: expands tight against the hole for a reliable structural hold.
- Grade options: 304 for general use, 316 for salt and chloride exposure.
Common applications for stainless wedge anchors
- Structural fastening into solid concrete
- Dock, pier, and coastal equipment mounting (use 316)
- Railings, posts, and safety fixtures on concrete
- Outdoor machinery and base plates

Stainless Steel Wedge Anchors FAQ
What grades do wedge anchors come in?
304 and 316 stainless. Use 316 for coastal, saltwater, or road-salt exposure.
Can wedge anchors be used in block or brick?
No. Wedge anchors are designed for solid, cured concrete. In hollow block or brick, use a sleeve anchor.
Can a wedge anchor be removed?
Wedge anchors are essentially permanent. The stud can be cut or the nut removed, but the expanded body stays in the concrete.
