Hex Sleeve Anchors – 304 Stainless Steel

Our 304 stainless steel hex sleeve anchors are through-bolt expansion anchors designed for fastening into concrete, brick and stone. As the hex bolt is tightened, the cone pulls into the sleeve and expands it against the hole wall to create a secure fixing. The stainless steel construction suits wet, outdoor and marine environments.

Frequently Asked Questions

How does a sleeve anchor work?

The anchor consists of a hex bolt with an expansion sleeve around a tapered cone. As you tighten the bolt, the cone is drawn up into the sleeve, expanding it hard against the hole wall. This clamps the fixture to the base material with no curing time.

Why choose a stainless steel sleeve anchor?

304 stainless steel anchors are the standard choice for wet, outdoor, coastal and pool environments, and anywhere rust streaks would stain concrete or stone. They also avoid the coating damage that hot-dip galvanized anchors can suffer during installation.

How are sleeve anchors installed?

Drill a hole to the specified diameter and depth, blow out the dust, insert the anchor through the fixture into the hole, and tighten the hex head to the specified torque. Loads can be applied immediately — no waiting for adhesive curing.

Do you provide material certificates?

Yes. Material test certificates per EN 10204 3.1 are available on request, and our manufacturing is ISO 9001:2015 certified. RoHS and REACH compliance documentation can also be provided.
