Anchors & Concrete Fixings · Trade series (self-drilling hollow wall anchors) · Application guide Typical applications, the industries that specify self-drilling hollow wall anchors, and how to choose the right size, material and finish for the joint. Self-Drilling Hollow Wall 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 (self-drilling hollow wall anchors), and selection is driven by the size designation, 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 (self-drilling hollow wall anchors) - **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 Self-Drilling Hollow Wall Anchors Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Self-Drilling-Hollow-Wall-Metal-Anchors.webp) Application guide for Self-Drilling Hollow Wall Anchors to Trade series (self-drilling hollow wall anchors). The core duty of the type is 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. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below. ## Typical Applications for Self-Drilling Hollow Wall Anchors The most common settings where these are specified: - **Fit-out & drylining:** fixing to plasterboard, block and hollow wall where there is no solid backing. - **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment. - **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.

Quoting the standard on your order guarantees interchangeable dimensions between suppliers. ## Where Self-Drilling Hollow Wall 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 self-drilling hollow wall anchors outside the standard range? Length and corrosion protection are the usual specials. The load a fixing will take is decided by the concrete and the edge distance, not by ordering a longer anchor. 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. - **Head style:** flanged - **Mating screw:** matched machine screw - **Board thickness:** set by the anchor length - **Finish:** zinc-yellow plated ## Dimensions & Specifications (Trade series (self-drilling hollow wall anchors)) | Point form | Head style | Mating screw | Board thickness | Finish | | --- | --- | --- | --- | --- | | self-drilling | flanged | matched machine screw | set by the anchor length | zinc-yellow plated | | self-drilling | countersunk | matched machine screw | set by the anchor length | zinc-yellow plated | 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 ### Are Self-Drilling Hollow Wall Anchors made to a recognized standard?
