Technical specification

Property	ORA — general-purpose wedge anchor
Anchor type	Wedge (expansion) anchor
Material	Carbon steel
Coating	Zinc plated 5–8 µm (ORA) / hot-dip galvanized 40 µm (ORA-G)
Concrete	Solid, uncracked concrete

The ORA wedge anchor: general-purpose fastening in concrete

The ORA is a mechanical wedge (expansion) anchor from Adit Ltd., designed for fast, reliable general-purpose fastening into solid, uncracked concrete. It delivers good quality at a competitive price and is backed by pull-out testing at the Israeli Standards Institute local laboratory. The ORA does not carry a European ETA approval and is intended for general, non-structural fixings.

How a wedge anchor works

A wedge anchor is a torque-controlled expansion anchor. It is inserted into a pre-drilled hole in concrete, and as the nut is tightened the cone at the base of the bolt draws up into an expansion clip. The clip presses outward against the walls of the borehole, creating the friction and interlock that hold the anchor in place. This makes the ORA quick to install and immediately loadable once tightened to the specified torque.

Installation stages

Drilling — drill a hole to the diameter and depth specified for the anchor size, using a hammer drill in solid concrete.
Cleaning the hole — blow out and brush the borehole to remove drilling dust for reliable expansion.
Inserting the anchor — drive the ORA through the fixture into the hole until the required embedment depth is reached.
Tightening — tighten the nut to the specified torque so the expansion clip sets against the concrete.

ORA vs. ORA-G — choosing the coating

Both versions are the same carbon-steel wedge anchor; only the corrosion coating differs:

ORA — zinc plated 5–8 µm, for dry indoor environments.
ORA-G — hot-dip galvanized 40 µm, for outdoor and humid environments where extra corrosion protection is needed.

When to move up to a structural anchor

The ORA is a general-purpose anchor. When a project specification calls for a European ETA approval, cracked-concrete performance, seismic loads or approved design load values, choose an ETA-approved anchor such as the MTP-X. For stainless-steel corrosion resistance, see the MTP A4 or MTH A4.

Quality and testing: the ORA range is backed by Israeli Standards Institute laboratory pull-out and coating tests.
Competitive price: an excellent price-to-performance ratio for general fixings, in stock for fast supply.
Full product family: if the job turns structural, we offer the ETA-approved MTP and MTH wedge-anchor ranges.

Frequently asked questions

When should I choose the ORA, and when the MTP-X?

Choose the ORA for general, non-structural fixings where price is the deciding factor. Choose the MTP-X when a European ETA approval, cracked concrete, seismic loads or design load values are required.

What is the difference between the ORA and the ORA-G?

The coating only. The ORA is zinc plated (5–8 µm) for indoor use; the ORA-G is hot-dip galvanized (40 µm) for outdoor and humid environments. Both are the same carbon-steel wedge anchor.

Does the ORA have a European ETA approval?

No. The ORA is a general-purpose wedge anchor backed by Israeli Standards Institute laboratory testing, but it does not carry a European ETA. For structural anchoring with an ETA approval, use the MTP-X.

Is the ORA suitable for cracked concrete or seismic loads?

No. The ORA is intended for solid, uncracked concrete and general fixings. For cracked concrete, seismic loads or approved design values, use an ETA-approved anchor such as the MTP-X.

What testing backs the ORA?

The ORA is backed by pull-out testing at the Israeli Standards Institute local laboratory, and the ORA-G additionally has a hot-dip coating thickness test. Both test reports are available in the Downloads section above.
