Soft Block Anchor 70mm
The Soft Block Anchor 70mm is a specialist fixing designed for reliable anchoring in soft
masonry substrates such as aerated concrete (Thermalite), lightweight blocks and other lowโdensity
blockwork. With an aggressive expansion design and deep engagement, this 70mm anchor provides
secure, loadโbearing fixings where standard plugs and screws can easily pull out.
The Soft Block Anchor 70mm has been developed to overcome the challenges of fixing into soft,
friable blocks where conventional plastic plugs provide inconsistent performance. Its design
allows the anchor to expand effectively within lowโdensity material, creating a secure mechanical
interlock while minimising the risk of the substrate crumbling around the fixing.
Typically used with a compatible screw (check product spec), the 70mm length provides deeper
embedment into soft blockwork, improving load capacity and overall security of the fixing. This
makes it an excellent choice for mounting timber battens, window and door frames, cable trays,
pipe clips, brackets, rails and other fixtures to aerated or lightweight block walls.
Suitable for internal applications (and some sheltered external uses depending on screw/fixture
choice), the Soft Block Anchor 70mm is widely used by builders, electricians, plumbers and
installers who regularly work with modern lightweight masonry.
Typical Use Cases
- Fixing timber battens and grounds to aerated / lightweight concrete blocks.
- Mounting window and door frames in soft block reveals (as part of a suitable fixing system).
- Securing pipe clips, cable trays, trunking and conduit to soft block walls.
- Installing brackets, rails, shelving supports and light services.
- General mediumโduty fixing into lowโdensity blockwork where standard plugs fail.
Installation & Usage Tips
- Use the correct drill size: Drill the hole diameter and depth specified for the anchor to achieve proper expansion.
- Drill in rotary mode only: Avoid hammer action in very soft blocks to reduce substrate damage.
- Clean the hole: Remove dust and debris before inserting the anchor to improve grip.
- Use appropriate screws: Match screw gauge and length to the anchor and fixture thickness as per manufacturer guidance.
- Avoid overโtightening: Tighten screws firmly but do not overโdrive, which can crush soft blockwork and reduce holding power.
Technical Information (Typical)
Exact details may vary by manufacturer; always refer to the product label or technical data
sheet for your specific Soft Block Anchor 70mm. Typical characteristics include:
- Type: Expansion anchor/plastic plug for soft/lightweight blockwork.
- Length: 70mm overall anchor length (approx.).

Frequently Asked Questions (FAQs)
1. What is a Soft Block Anchor used for?
A Soft Block Anchor is used to create strong, reliable fixings in lowโdensity masonry such as
aerated and lightweight blocks, where conventional wall plugs can easily pull out or spin in
the hole. The 70mm version is suited to mediumโduty applications.
2. Can I use a hammer drill when installing these anchors?
In very soft blocks, it is usually recommended to drill in rotaryโonly mode to avoid blowing
out or crumbling the hole. Use a sharp masonry bit and follow the manufacturerโs guidance for
drilling speeds and modes.
3. What size drill bit do I need?
The required drill diameter is specified by the anchor manufacturer (e.g. 8mm, 10mm, etc.).
Always match the drill size and depth to the instructions on the packaging to ensure proper
anchor expansion and load performance.
4. Which screws should I use with a Soft Block Anchor 70mm?
Use the screw type and gauge recommended on the pack โ typically a wood or multipurpose screw
of appropriate diameter and length to suit both the anchor and the fixture thickness. Using
incorrect screw sizes can reduce holding strength.
5. Are Soft Block Anchors suitable for heavy structural loads?
Soft Block Anchors are generally intended for light to mediumโduty fixings in soft blockwork.
For heavy structural loads or safetyโcritical applications, consult an engineer and use
anchors specifically approved and rated for those loads in the given substrate.
Common Uses / How to Use
To get the best from the Soft Block Anchor 70mm:
- Mark the fixing position on the soft blockwork.
- Drill a hole to the specified diameter and depth using rotaryโonly mode where possible.
- Clean out dust from the hole with a blower or brush.
- Insert the Soft Block Anchor 70mm fully into the hole until flush with the surface.
- Position the fixture (batten, bracket, clip, frame, etc.) over the anchor.
- Drive the recommended screw into the anchor until the fixture is secure; avoid overโtightening.
