Chemical Anchors

146 products · Chemical Anchors

Chemical anchors fix threaded rods, plugs and reinforcing bars in concrete and masonry, even under high loads. They work with a resin that hardens in the hole and bonds to both the substrate and the fixed element. The collection includes products from Fischer, SPIT, Bossong, DeWalt, Unifix, Kimia and Bonfante.

Types available in the collection

  • Cartridge resins: epoxy, hybrid, polyester and vinylester, including styrene-free.
  • Adhesive capsules and glass ampoules for chemical anchoring.
  • Threaded rods and spacer bushes.
  • Plugs and fixing kits, and hand pumps for cleaning holes.

How to choose

Choose the resin according to the substrate (concrete, solid or hollow brick), the load to be supported, the temperature and the curing time. Cleaning the hole and following the manufacturer's instructions are essential for a secure hold. Our team can help you find the right product.

AMES works on a quotation basis: not all items are available for immediate delivery. If you are unsure about your choice, tell us the material, substrate and quantity and we will reply with the alternatives available. For a made-to-measure supply, write or call us and we will help you prepare the quotation.

Frequently asked questions: Chemical Anchors
When is a chemical anchor needed?

When the fixing must carry high loads on concrete or masonry, or when the base is fragile and a mechanical anchor would risk splitting it. It is the system used to fix threaded rods, reinforcing bars and anchors in concrete, even with reduced edge distances. The resin works inside the hole and bonds the base to the fixed element.

Epoxy, vinylester, polyester or hybrid: which resin should I choose?

The resin should be chosen according to the base, the load and the fitting conditions, which the manufacturer states in the data sheet. Epoxy resins are often used for heavy loads, while vinylester and polyester resins are for more general fixings. Hybrids combine characteristics of both families. The catalogue also has styrene-free versions, for those looking for a resin with less odour.

Cartridge, capsule or glass vial: how does the system change?

Cartridges are used with a dispensing gun and a static mixer, and are practical when there are many holes. Capsules or vials are single-use and are placed in the hole before the rod, which breaks them as it is turned by the drill. The type should be chosen according to the number of holes and the equipment available, such as the gun or the drill.

Why should the hole be cleaned before injecting the resin?

A hole with dust or water reduces the bond of the resin, and the fixing loses its holding without any visible sign. For this reason the hole is blown out with compressed air or a hand pump, then brushed with a brush of the right diameter, and the cleaning is repeated until no more dust comes out. The catalogue includes pumps and brushes for this stage.

How long should I wait before loading the fixing?

The curing time of the resin is not the same for all products and changes with the temperature of the base and the material. The fixing must not be loaded or stressed until the resin has cured. Always check the time given in the data sheet for the product chosen, and do not rely on a generic figure.

Who uses chemical anchors?

They are used by plant installers, carpenters, structural metalwork fitters, industrial maintenance staff and technicians fixing machinery, railings, stairs and pipework in concrete. It is a job where fitting matters as much as the product, so it is worth following the instructions carefully.

How should resins be handled safely?

Resins can irritate skin and eyes, so wear gloves and safety glasses and work in a well-ventilated area. Read the product's safety data sheet, which sets out the hazards and what to do in case of contact. Do not leave open cartridges or mixer nozzles within reach of children, and dispose of residues according to local rules.
