Anchors & Concrete Fixings · Trade series (slotted drive-in anchors) · Application guide Typical applications, the industries that specify hammer-drive gecko anchors, and how to choose the right size, material and finish for the joint. Hammer-Drive Gecko Anchors are used for fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel. They are manufactured to Trade series (slotted drive-in anchors), and selection is driven by the thread size, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel - **Governing standard:** Trade series (slotted drive-in anchors) - **Thread size range:** M6 to M8 - **Category:** Anchors & Concrete Fixings Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Hammer-Drive Gecko Anchors Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Hammer-Drive-Metal-Gecko-Anchors.webp) Hammer-Drive Gecko Anchors are selected when an assembly calls for fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel. This application guide to the Trade series (slotted drive-in anchors) type covers concrete end-uses, the specification checklist, correct installation, and where an alternative fastener performs better. Stocked across roughly M6 to M8, they cover general to heavy-duty work. ## Typical Applications for Hammer-Drive Gecko Anchors The most common settings where these are specified: - **Maintenance & repair (MRO):** a stocked size for servicing existing plant where the original fastener spec must be matched. - **Fabrication & metalwork:** bench and on-site assembly of steel frames, enclosures and weldments. - **Structural fixing to concrete:** base plates, brackets, rails and steelwork bolted to a concrete slab or wall. - **Building services:** suspending cable tray, ductwork, sprinkler pipe and unistrut from a soffit. - **Plant & machine installation:** holding down machines, presses and conveyors on a factory floor.

This product spans M6–M8; check the full table below for the exact dimensions of each size. - **Material:** Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance. - **Environment:** For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient. - **Standard:** This product is supplied to Trade series (slotted drive-in anchors). Quoting the standard on your order guarantees interchangeable dimensions between suppliers. ## Where Hammer-Drive Gecko Anchors Are Not the Right Choice Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure. Custom manufacturing · Made to drawing ## Need a hammer-drive gecko anchors outside the standard range? Embedment depth, thread size, body length and corrosion protection are the variables; capacity remains a concrete design value, not a property of the anchor alone. Made by hot forging or thread rolling. Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Side view and top view, drawn to the dimensions in the table below and redrawn for any size selected. - **Material and finish:** carbon steel, colour zinc plated - **Installation tool:** hammer - **Substrate:** concrete and solid brick - **Spanner required:** no ## Dimensions & Specifications (Trade series (slotted drive-in anchors)) | Thread size | Material and finish | Installation tool | Substrate | Spanner required | | --- | --- | --- | --- | --- | | M6 | carbon steel, colour zinc plated | hammer | concrete and solid brick | no | | M8 | carbon steel, colour zinc plated | hammer | concrete and solid brick | no | Inside the plant ## Manufactured in our own plant This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided. 1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift. 2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g. 3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1. 4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227. ## Frequently Asked Questions ### What material should Hammer-Drive Gecko Anchors be for outdoor use? For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate. ### Are Hammer-Drive Gecko Anchors made to a recognized standard? Yes — they are manufactured to Trade series (slotted drive-in anchors), so dimensions are interchangeable between suppliers when you quote the standard on your order. ### What are Hammer-Drive Gecko Anchors used for? Fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel.
