Wedge anchors, sleeve anchors and drop-in anchors.
Mechanical anchors for cracked and uncracked concrete, in zinc-plated and stainless steel. Published load values are characteristic, not approved — if your fixing needs an ETA or ICC-ES report, say so at RFQ and we quote an approved line or decline the job.
Specify it once
What to put on the drawing or the PO.
The four lines below decide whether the parts fit, hold and survive. Nine quoting delays out of ten are one of them missing.
- Base material: cracked or uncracked concrete, and the concrete strength class the loads were calculated at.
- Whether an ETA or ICC-ES evaluation report is required — a safety-critical fixing without one is a specification problem, not a price problem.
- Embedment depth and edge distance, because a wedge anchor near an edge fails by concrete cone, not by steel.
- Hole diameter and drilled depth to the anchor manufacturer’s data, not to the nearest bit in the van.
Where it goes wrong
Mistakes we see on incoming drawings.
We will flag these before production rather than after the first inspection. If a mistake is already in the drawing, we say so in writing on the quote.
- Using a mechanical expansion anchor in brick or block, where there is nothing for the wedge to expand against.
- Reading a published tensile value as a design value without the concrete, edge and spacing factors.
- Reusing a wedge anchor after removal — the expansion clip does not seat twice.
Common questions
Anchors — answered before you ask.

Are your anchors ETA or ICC-ES approved?
The standard wedge and sleeve anchors we stock are not ETA-rated, and we will say that before you specify one for a safety-critical fixing. Approved anchors are quoted on request from audited lines, with the evaluation report attached.
What embedment depth should I use?
The depth published for the specific anchor and diameter, measured from the concrete surface, not from the fixture. Increasing it beyond the data does not increase the load in a predictable way.
Can I use a wedge anchor in brick?
No. Mechanical expansion anchors need a competent material to expand against; in masonry use a chemical anchor with a screen or a sleeve designed for the block.
