About this anchor

This is a anchor in 304 Stainless Steel, at strength class A2-70, supplied plain, with an M8 thread and a 80 mm length. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.

An anchor transfers load from a fixture into masonry or concrete, expanding or bonding against the drilled hole so the fixing develops its strength from the base material. Used for racking, handrails, façades, plant and machinery bases, and any fixing into brick, block or concrete that has to take a working load.

Plain (self-colour) means no coating. On 304 and 316 stainless that is fine — the alloy passivates on its own. On carbon steel it will rust, so choose a coated option instead.

A2-70 is 304 stainless, cold worked to a 700 MPa minimum tensile and 450 MPa 0.2% proof stress. It is the default stainless grade for general purpose bolts and screws.

Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
