Choosing the Right Stainless Steel Tam Anchor
Choosing the Right Tam Anchor
1) What is a Tam anchor & when to use it?
A Tam anchor (often sold as Tam anchor bolt / Tam wedge bolt) is a mechanical expansion anchor for fixing into concrete and masonry. It usually consists of:
A hex-head or external hex bolt
A slotted expansion sleeve / shield
A tapered cone section at the end that expands the sleeve when tightened
When you tighten the nut/bolt, the cone is pulled into the sleeve and the sleeve expands radially into the hole, locking the anchor in the base material. Many suppliers market Tam anchors specifically for hard concrete, masonry and even some softer base materials.

Use a Tam anchor when you need:
A medium-duty mechanical fixing into concrete or masonry
A through-fixing that goes through the base plate and is tightened from the front
A simple installation with standard drilling and spanner work
Common applications:
Handrails, gates, guardrails and balcony railings
Cable trays, pipe supports, brackets, sign boards
Window grills, shutters, barriers, light structural frames
General building hardware where chemical anchors are not required
Mechanical Properties (Guide)
Mechanical Properties (Guide) – Tam Anchors
Tam anchors are expansion anchors. Their performance depends on both the steel of the anchor and the strength and condition of the concrete/masonry.
1) Steel properties
Tam anchors are made from:
Mild steel (for zinc-plated / HDG versions)
Stainless steels 201 / 304 / 316 for corrosion-resistant versions
Vigor Fasteners
+1
Typical characteristics (conceptual):
Tensile strength broadly similar to common structural/fastener steels used in anchor systems (around the range of many 5.8–8.8 equivalents for MS; comparable strengths for stainless depending on exact grade).
Adequate shear and tensile capacity for medium-duty anchors when sized and embedded correctly.
In design, the steel limit state includes:
Tension steel failure (necking & pull-through of stud/bolt)
Shear steel failure (stud shearing off at or near concrete surface)
However, in many real cases, concrete breakout or pull-out will govern before the steel reaches full theoretical capacity.

Frequently Asked Questions
What is a Tam anchor?
A Tam anchor is a mechanical expansion anchor used to fix items into concrete or dense masonry.
It typically has a bolt or threaded stud, an expansion sleeve, and a tapered cone. When you tighten the nut/bolt, the cone is pulled into the sleeve, which expands against the hole wall and locks the anchor in place.
Where are Tam anchors commonly used?
Tam anchors are used for medium-duty fixings such as:
Handrails, guardrails, gates, grills
Brackets, cable trays, pipe supports
Sign boards, window grills, frames
Light structural frames and machinery supports
They are popular in general construction and fabrication where a quick, dependable mechanical anchor is needed.
What base materials can I use Tam anchors in?
Best suited for:
Solid concrete (slabs, beams, columns)
Dense masonry (good quality solid brick, block, or stone)
Not recommended for:
Very weak, hollow, or crumbly masonry
Thin sections where there is not enough embedment depth
For hollow/weak block, a frame anchor or chemical anchor is usually better.
Can Tam anchors be used near the edge of concrete or brick?
Yes, but with care:
Every anchor size needs a minimum edge distance (and minimum spacing to other anchors).
If too close to an edge, concrete or brick can break or chip out under load.
If you must fix close to edges:
Use smaller anchors with reduced loads, or
Consider chemical anchors with proper design.
Are Tam anchors suitable for overhead or safety-critical applications?
They can be, but:
Only if the anchor type, size, base material, and installation are suitable and properly designed/verified.
For safety-critical fixings (e.g. lifelines, heavy suspended loads, critical guardrails), you should use tested anchors and follow engineered design.
For non-critical items (grills, light brackets) normal practice and manufacturer guidelines are usually sufficient.
