Square Plate Washers

Our Square Plate Washers provide robust load-bearing support for threaded rod systems, structural fixings, and heavy-duty installations. Their wide surface area helps distribute force and reduce pressure on softer materials, making them ideal for use in steel frameworks, bracketry, and pipe support systems.

Types Available:
- Square Plate Washers
- Top Hat Washers
Finish Options:
- Bright Zinc Plated (BZP) – For indoor and low-exposure environments
- Hot Dipped Galvanised (HDG) – Offers excellent corrosion resistance for external use
- Stainless Steel (A316 / A4) – Best for marine, chemical, or high-humidity environments
Thickness Options:
3mm and 5mm to suit varied structural needs
Hole Sizes Available:
M6, M8, M10, M12, and M16

These washers ensure a secure connection by preventing pull-through and protecting the mounting surface, especially in high-load or vibration-prone environments.
