Square Washer
Heavy-Duty Load Distribution for Structural Applications
Square washers are designed to provide increased surface area and load distribution, making them ideal for structural, construction, and heavy-duty applications. Their unique square shape prevents rotation and enhances stability, especially when used with bolts, anchors, and threaded rods.
✅ Enhanced Load Distribution – Prevents damage to surfaces by evenly spreading load pressure.
✅ High-Strength Material – Available in carbon steel, stainless steel, alloy steel, and brass.
✅ Corrosion Resistance – Coatings include hot-dip galvanized, zinc-plated, and black oxide for durability.
✅ Prevents Bolt Pull-Through – Larger surface area prevents bolts from sinking into soft materials.
✅ Compatible with Various Fasteners – Works with hex bolts, carriage bolts, and anchor systems.
