Austenitic stainless steel dowel for sheet‑metal installation, 40 mm anthracite. Quantity per package: 100 pcs. 9AN40USN

Universal mounting plug for various substrates

The USN 40 mm plug in anthracite colour is a solution designed for direct fastening of sheet‑metal parts and other light structures — from cornice covers to motion sensors or small lighting. It does not require pre‑drilling holes, and its design allows quick and safe installation in concrete, brick, blocks and other medium‑hardness building materials.

Flexible V‑shaped elements made of glass‑fiber‑reinforced nylon provide a stable pull‑out force even under dynamic loads. The EPDM seal in the plug head eliminates thermal bridges — important for the thermal insulation of external walls. The material is resistant to UV radiation, temperature changes and ageing, guaranteeing long‑term functionality outdoors.

The plug head has an aesthetic styling — it does not look like a typical dowel, and its anthracite colour fits modern façade details and metal constructions. It works without additional fastening elements — just strike it into the substrate and it’s ready.

Why it works well?

• Drill‑free installation — no need to prepare holes, no dust or noise.

• No thermal bridge — the EPDM seal prevents heat conduction through the plug.

• Resistance to outdoor conditions — glass‑fiber‑reinforced nylon and EPDM do not crack, yellow, or lose strength under sun or rain.

• Universality — suitable for both dry and wet substrates: concrete, blocks, brick, and even some types of plasterboard.

• Visual discretion — the anthracite head is unobtrusive, ideal for final architectural details.

This is not a regular dowel. It is a tool for the installer who needs a fast, clean and durable connection without compromises. Used by professionals on exterior and interior construction sites — where both function and appearance matter.
