20MM Unifix

It’s designed for hard substrates like concrete, masonry, and stone, and is suitable for fastening in drywall, plasterboard, blockwork, and brick when used with the appropriate screw and installation method specified for the system.

UNIFIX 20MM uses a special grip and a wide thread pitch to resist pull‑out in hard substrates, enabling fast and secure screw anchoring with less reliance on predrilled wall plugs while delivering reliable performance in heavy‑duty applications.

Ideal for medium‑ to heavy‑duty fixings such as mounting in industrial facilities and commercial buildings—panels, light fixtures, switches, power tools, air conditioners, and other substantial fixtures requiring stable, long‑lasting anchors.

General steps: verify substrate suitability and load rating; drill a correctly sized hole for the 20MM system; clean the hole; insert the anchor; drive the screw to the recommended torque until the fixture is secure while avoiding over‑tightening; then test the mounting to ensure stability.

Yes. Use the recommended drill size and screws for your substrate, keep holes clean, and ensure you are within the system’s rated load across the temperature range. Avoid exceeding loads and recheck secure attachment after installation, especially in extreme conditions.

UNIFIX 16MM is generally suited for lighter loads and smaller fixtures, while UNIFIX 20MM provides higher pull‑out resistance and greater load capacity in hard substrates. For bigger or heavier installations, the 20MM system tends to offer better performance and security. See: https://fepy.com/product/unifix-16mm-fixing-system

UNIFIX 25MM targets larger fixtures and higher load demands than the 20MM. If your project involves heavier items or larger panels, the 25MM variant may be more suitable. See: https://fepy.com/product/unifix-25mm-fixing-system

For very heavy panels or demanding applications, the 30MM option typically offers the strongest performance and greatest load capacity. If your project sits in the mid to high range, compare the load ratings and substrate recommendations to decide. See: https://fepy.com/product/unifix-30mm-fixing-system

If you’re not satisfied, you can pursue the standard return options offered by Fepy within their policy. It’s best to review the return terms for eligibility and the condition requirements for returned items.

Ensure you use compatible screws and follow the substrate‑specific guidelines, keep holes clean, avoid over‑tightening, and verify the load after installation. Choosing the correct variant (20MM, 16MM, 25MM, or 30MM) based on fixture weight and substrate will also help achieve optimal performance.
