Square Pre Galvanized Strut Washers are designed for use with standard 1-5/8 inch strut channel systems to distribute load, prevent pull-through, and create secure attachment points in framing and support assemblies. Each washer is stamped from durable pre galvanized steel for reliable corrosion resistance in construction, electrical, HVAC, and industrial installations.
These square washers fit the full 1-5/8 inch strut footprint and provide a stable bearing surface when tightening bolts through channel slots or mounting brackets. They are ideal for applications that require reinforcing the connection area or improving clamp load on softer or slotted materials.
Available in multiple bolt diameters including 1/4 inch, 3/8 inch, 1/2 inch, and 5/8 inch, allowing compatibility across a wide range of strut hardware and mounting configurations.
