ProFix 20-Piece Expansion Anchors, M8 × 80 mm

What it is for

An anchor is not a bigger plug. It transfers load into the base material mechanically — a sleeve expands against the hole, a bolt wedges — and the stated load only applies to the material it was tested in. Fixing a heavy item into brick with an anchor rated for concrete is the most common reason this category gets a complaint.

These are zinc plated anchors for concrete and solid masonry, with the hole diameter, minimum hole depth and recommended torque listed per variant. Check the substrate first; if it is a hollow block or a cavity, an anchor is the wrong product and a chemical resin or a different fixing is needed.

Specification detail

20 Expansion Anchors covering M8 × 80 mm, zinc plated steel, supplied bolt and sleeve assembled. Each size is rated for a stated hole diameter and minimum embedment depth in concrete of a given strength class; torque values are listed on the case.

• Load carried by expansion in the base material, not by the screw thread
• zinc plated for concrete and solid masonry — not for hollow block or cavity
• Hole diameter, minimum depth and torque stated, because the load depends on all three
• Sleeve and bolt supplied assembled as one unit, so the two cannot be mismatched
