Sleeve anchors are expansion anchors with a full-length split sleeve around a threaded stud or bolt. They are pushed through the fixture into a drilled hole, and tightening the nut or bolt draws a cone into the sleeve, which expands against the hole. The long sleeve makes them suitable for concrete, solid brick and block.
Linkworld supplies sleeve anchors from M6 to M20 in zinc plated or galvanised carbon steel and stainless steel, with hex nut, hex bolt and countersunk heads. We pack in bulk cartons or in your own branded packs, and other sizes can be made to your drawing or sample.

- Handrails base plates and wall brackets
- Door and window frames countersunk sleeve anchors for flush fixing
- Shelving and fixtures fixing into brick and block
Choosing Sleeve Anchors
- Head style: hex nut for general fixing, hex bolt where the bolt must be removed, countersunk for a flush finish.
- Length: cover the fixture thickness plus the embedment the manufacturer or designer requires.
- Finish: zinc for indoor use, galvanised for outdoors, stainless steel for coastal and wet areas.
- Base material: sleeve anchors suit concrete and solid masonry.
Anchor selection for structural fixings should follow the project design.
Common Purchasing Mistakes
Confusing sleeve anchors with wedge anchors. A sleeve anchor has a full-length sleeve; a wedge anchor has a short clip. They are different products.
Ordering by diameter only. Give the length and head style.
Zinc anchors outdoors. Use galvanised or stainless outdoors.
One code for all heads. Give each head style its own code.
