The Stainless Steel Sleeve Anchor (Hex Nut Type) is the most versatile masonry fastener for securing heavy loads to base materials that may be porous or hollow. Unlike wedge anchors that stress the concrete at a single point, our Stainless Steel Sleeve Anchor features a full-length tubular sleeve that expands evenly along the anchor’s body. This distributes the holding force over a larger area, making it the safest choice for brick, block, and older concrete.
Product Overview: Stamped with “304” or “316” for authenticity, our Stainless Steel Sleeve Anchor is manufactured from premium Stainless Steel A2 (304) or marine-grade A4 (316). It is pre-assembled for quick installation: simply drill a hole the same diameter as the anchor, insert, and tighten.

Engineering Insight: Sleeve Anchor vs Wedge Anchor
Why choose a Stainless Steel Sleeve Anchor over a Wedge Anchor?
- Versatility: Wedge anchors only work in solid concrete. A Sleeve Anchor works in almost anything masonry, including soft brick and grout lines, because the expansion sleeve is longer and more forgiving.
- Hole Sizing: With a Stainless Steel Sleeve Anchor, the hole size equals the anchor size (e.g., use a 10mm drill bit for an M10 anchor). This simplifies on-site tooling.
For more details on expansion mechanisms, please refer to the Anchor bolt entry on Wikipedia.
Installation Guide
- Drill: Drill a hole using a hammer drill. The bit diameter should match the anchor diameter (e.g., M10 anchor = 10mm bit).
- Clean: Remove dust from the hole.
- Insert: Drive the Stainless Steel Sleeve Anchor through the fixture and into the hole until the washer sits flush.
- Tighten: Turn the nut 2-4 turns. This pulls the cone up, expanding the sleeve against the masonry.
Frequently Asked Questions (FAQ)
Q: Can I remove it later?
A: Yes, partly. You can unscrew the nut and remove the bolt, but the expanded sleeve will likely remain stuck inside the wall forever.
Q: What is the minimum embedment?
A: Generally, you need to embed at least 4-5 times the anchor diameter into the base material for full holding power.
