Timco Zamac Nail In Anchors in zinc are a light-duty hammer-set fixing designed for attaching sheet metal, plastic, or timber directly to concrete and masonry substrates. The zamac anchor body expands as the pin is driven home, locking the fixing into the base material without any need for a setting tool or adhesive. If you want a fixing that goes in fast and holds reliably, these are a sensible choice for volume work.
The zinc construction gives a reasonable level of corrosion resistance for internal and sheltered external applications. With a 6.0mm diameter across the range and lengths from 30mm to 65mm, there is enough choice to suit varying material thicknesses and base material depths without overcomplicating selection on site.
Where Zamac Nail In Anchors Get Used
These anchors suit jobs where speed matters more than heavy-duty load capacity. Cable management fixings, conduit saddles, sheet metal brackets, plastic trim, and lightweight timber battens are all typical applications. They are widely used in first-fix electrical work, mechanical services installations, and light partitioning where the fixing has to go in quickly and the load is not significant.
Choosing the Right Length
As a general rule, you want the anchor to penetrate the base material by at least 25mm after passing through the material being fixed. The 6.0 x 30mm suits thin sheet material straight onto masonry. The 6.0 x 65mm gives more penetration depth where the fixing substrate is a softer block or where the material being fixed is thicker. Pick the length based on what you are going through, not just what looks about right.
Zamac nail-in anchors are sold in boxes of 100, which keeps things tidy on site and makes it straightforward to keep stock levels sensible. At 6.0mm diameter throughout the range, you only need one drill bit regardless of which length you are using.
Pro Tip: Pre-drill to the correct depth before driving the pin: if the hole is too shallow the pin will not fully seat and the anchor will not expand properly, leaving you with a fixing that looks fine but is not.
Zamac nail-in anchors are used across a range of light-duty fixing tasks in construction and fit-out work. Electricians and mechanical installers reach for them when fixing conduit saddles, cable tray brackets, and back boxes to concrete or blockwork walls. They are also commonly used for securing plastic trim, sheet metal cladding supports, and lightweight timber battens where the fixing needs to go in quickly without specialist equipment.
The 6.0mm diameter suits most standard applications in this category, and the four available lengths cover the majority of material thickness combinations likely to be encountered on a typical build or refurbishment site.

Key Specifications
Diameter: 6.0mm
Available lengths: 30mm, 40mm, 50mm, 65mm
Material: Zamac (zinc alloy)
Finish: Zinc
Box quantity: 100
Setting method: Hammer-driven pin
Not suitable for: Not recommended for overhead applications such as suspended ceilings or any fixing where the anchor is subject to sustained tension loading from below. Not suitable for use in soft or aerated blockwork where reliable expansion cannot be achieved.
Drill a 6.0mm hole into the concrete or masonry to the required depth, making sure the hole is at least as deep as the embedded portion of the anchor. Clear dust from the hole before inserting the anchor body. Position the material to be fixed over the anchor, then drive the pin firmly with a hammer until the head is fully flush. The pin expands the anchor body inside the substrate as it is driven, locking the fixing in place.
Do not attempt to insert the anchor into an undersized or partially drilled hole. The pin must be driven in one continuous action for the anchor to expand correctly. If the pin is only partially set, the fixing will not achieve its rated hold.
Select the correct anchor length based on the thickness of the material being fixed plus a minimum 25mm embedment into the base material
Fit a 6.0mm masonry drill bit and drill to the required depth in the concrete or masonry substrate
Clear loose dust and debris from the hole using a brush or compressed air
Insert the zamac anchor body into the hole so it sits flush with or just below the surface
Position the sheet metal, plastic, or timber component over the anchor
Drive the pin home with a hammer in one firm, continuous action until the head is fully seated
Check the fixing is tight and the pin head is fully flush before applying any load
Can these nail-in anchors be used in aerated concrete blocks?
No. Zamac nail-in anchors rely on the anchor body expanding against a dense substrate. Aerated or lightweight blocks do not provide sufficient resistance, and the fixing will not hold reliably. Use a specialist aerated block anchor for those applications.
What drill bit size do I need for the 6.0mm zamac nail-in anchors?
You need a 6.0mm masonry drill bit for all four lengths in this range. The diameter is consistent across the 30mm, 40mm, 50mm, and 65mm sizes, so one bit covers the lot.
Can the pin be removed and the anchor reused once it has been set?
No. Once the pin has been driven and the anchor has expanded, the fixing is permanent. These anchors are designed for single use and cannot be removed cleanly or reset once installed.
Timco Zamac Nail In Anchors are manufactured from zamac, a zinc-based alloy known for good dimensional stability and moderate corrosion resistance. The anchor operates on a simple mechanical expansion principle: driving the steel pin forces the zamac body to expand against the walls of the drilled hole, creating a friction-based hold. The zinc finish provides additional surface protection suitable for dry internal and sheltered conditions.
