Dimensions are nominal values from the governing standard. Confirm the tolerance class for your application before ordering.

Applications & Industries

Where Plastic Expansion Wall Plugs are used, and what decides the specification in each case. Stocked from 5 to 10 (nominal diameter).

Industries that specify Plastic Expansion Wall Plugs

Interior fit-out Plastic plugs carry trim, light fittings and cabinet rails.
Residential building Nylon bodies suit brick, concrete and gypsum board.
Retail display Light-load fixing without specialist tooling.
Maintenance Common sizes cover most small wall fixings.
Construction & structural Base plates, brackets and steelwork fixed to concrete.
Building services Suspending tray, duct, pipe and sprinkler runs from a soffit.

Typical applications

matching the plug diameter to the drill and the screw shank
choosing a wood or self-tapping screw so the thread expands the body
selecting tube length for the substrate thickness
keeping the load light and static
making a load-bearing threaded fixing in concrete or masonry
fixing a steel fixture through to a solid substrate

Service conditions to specify against

Marine and coastal: Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
Temperature ceiling: The polymer feature sets the limit, not the steel: nylon softens above roughly 120 °C, so an all-metal locking type is the correct choice on hot assemblies.
The concrete governs: Capacity is a property of the base material and the geometry — grade, edge distance, spacing and cracked or uncracked — not of the anchor alone. Work to the anchor manufacturer's ETA or ICC-ES report.
Hole preparation: Drilled diameter, depth and cleanliness are part of the specification; an uncleaned hole is the single most common cause of a failed anchor.

Where to use something else

Do not use a light-duty plastic plug for overhead or safety-critical loads; ETAG 020 assessment is per manufacturer and per substrate.
Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.

Plastic Expansion Wall Plugs conform to JG/T 139 / ETAG 020. As anchors & concrete fixings, they are specified by the dimensions in the table below; this page also covers materials, finishes and typical uses.

What Are Plastic Expansion Wall Plugs?

Plastic Expansion Wall Plugs are anchors & concrete fixings defined by JG/T 139 / ETAG 020. They are selected by nominal diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.

Specification Guides

Each size, material and standard of Plastic Expansion Wall Plugs has its own reference page with the figures for that one configuration.

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.

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.
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.
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.
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.
