    The 10mm Hammer Fixing with Plastic Pin & Short Expansion Zone is a hammer-driven fastener for external wall insulation (EWI) systems. The body is polyethylene and the glass-fibre–reinforced plastic pin delivers high impact resistance during installation while minimising thermal bridging. Its short expansion zone and innovative sleeve help the washer sit flush with the insulation for a stable, long-term fix. Recommended for securing polystyrene insulation in ETICS applications.

    Suitable Insulation Boards

    Insulation Type Compatibility
    EPS (Expanded Polystyrene) Compatible
    XPS (Extruded Polystyrene) Compatible
    Mineral Wool Not compatible
    PIR / Phenolic (e.g., Kingspan) Not compatible
    Wood Fibre Not compatible

    Compatible Substrates (ETA Categories A–E)

    ETA Category Substrate Compatibility
    A Concrete Compatible
    B Solid ceramic brick / silicate Compatible
    C Ceramic block Compatible
    D Lightweight aggregate elements Compatible
    E Aerated concrete (AAC) Compatible

    If the substrate condition is uncertain, carry out a pull-out test to confirm suitability.

    Key Features

    • Glass-fibre–reinforced plastic pin resists breakage and limits thermal bridging.
    • Short expansion zone for efficient anchorage and reduced drilling effort.
    • Innovative sleeve ensures a flush finish to the insulation surface.
    • Special connection flange improves stability under wind suction loads.
    • ETA-16/0509 assessed for EWI/ETICS applications.
    • Fast, reliable hammer-in installation.

    Sizes & Box Quantities

    Size (Ø10mm) Box Quantity
    70 mm 200 per box
    90 mm 200 per box

    Select length based on insulation thickness + adhesive layer + required embedment depth.

    Application

    Preparation

    • Mark out the fixing grid to suit the system design and wind-load zone.
    • Check for hidden services (cables/pipework) before drilling.
    • Use rotary-only mode for hollow blocks/AAC; use hammer mode for dense concrete and brick where appropriate.

    Installation steps

    1. Apply adhesive to boards per your EWI specification and place boards tightly with staggered joints.
    2. Drill perpendicular through the insulation into the substrate; clean dust from the hole.
    3. Insert the fixing body and hammer the plastic pin until the washer seats flush; do not over-drive or dish the surface.
    4. Install the specified number of fixings per board, adding extras around corners, openings and high-load zones.
    5. Proceed with basecoat and reinforcement mesh in line with the system specification.

    Fixing pattern & density

    • Typical guidance: 4–6 fixings per m², with increased density in edge and corner zones.
    • Maintain consistent edge distances; avoid placing fixings too close to board edges or through joints unless specified.

    Quality checks

    • Carry out pull-out tests where substrate variability is suspected.
    • Replace any fixing that spins or fails to grip; re-drill if necessary.

    Dead on fixings. Slapped 'em into dense concrete, hammer action was quick as anything, proper fast installation, felt completely secure against wind load. Value is brilliant for a plastic pin, didn't snap any. Only dropped a star 'cos I had to pull out my spare pin driver near the end. And you always wonder if the thermal bridging is *truly* the lowest possible compared to specialist kit, but for this price? Sorted.

    Good stable fix and fast installation using the hammer action, ETA info was spot on for my EPS boards. The glass-fibre pin feels proper robust. Docked a star because gauging the embedment depth was difficult and wish they did a 120mm size in this range. Bit annoying the box was short on units.

    Absolute liberty with this lot. box sed 200 units but we counted twenty fixings short for the run. wasted half a bloody hour sorting it out team stood there waiting for kit they thought they had. you cant trust the packaging Qty so the ETA cert is probably a load of pish two. shudda paid a bit more and got the 250 rawlplugs. now im forced to stop the job and run back to the yard. not worth the 'saving'. shocking. never agane

    Proper solid EWI fixing and a genuine time saver on site. Go-to fixings for EPS sound as a pound. That short expansion zone is bang on genuinely cut down the drilling effort and time needed amazing. GFR pin stopped the snapping—none of the breakages you get on the cheap rubbish. Hammered in quick. Got a perfect flush finish every time too. Held firm in Cat A and even the lightweight aggregate (Cat D). Really solid holding power. Delivery arrived earlier than expected. Top notch anchor.

    Alright, but a lot of *faff* getting them seated right. Brill delivery, can't fault that. Easy drilling, the short expansion zone was a godsend on the concrete block. But getting the washer truly flush was **Rubbish!** Took so much mucking about, tapping and re-tapping to stop the minor dishing. We had to use way more fixings on the corner zones than quoted (4/m²) wasn't enough so ran short on the 90s quick. OK for the EPS, but feel it's slightly overpriced for the installation hassle. Could be better.

    Rock solid hold on my Cat A concrete and they worked perfectly for the AAC blocks too (E-cat). The short expansion zone saved serious time and strain on the drilling front. Not one snapped pin, the glass-fibre pins are seriously tough, and every single fixing seated dead flush. That, and I had a quick call back from a tech expert to double check my fix calulation for an exposed elevation, which gave me total confidence. Good price, perfect performance. Spot on kit.

    ★★★★★ 5/5 ### Proper Job Fixings - Fast Install & Solved Our Uplift Issue Brilliant bit of kit, seriously good. Anchor worked perfectly on the solid concrete (Category A) and the install was a doddle. The **short expansion zone** cut down the drilling effort significantly, saved my energy on the scaffold. This product finally fixed a recurring wind uplift issue—they feel **rock solid** even where I doubled up the density on the corners. The **glass-fibre pin** didn't snap once while giving it some welly, and the innovative sleeve kept every washer perfectly flush, spot on for rendering later. The 90mm size was exact for the EPS boards. Seamless from ordering to site too, the driver was helpful and customer service gave excellent advice. I will not use anything else now.
