Stainless Steel Square Washer – Heavy-Duty Load Distribution Washer for Base Plates, Anchor Bolts & Structural Joints

The Stainless Steel Square Washer is a heavy-duty fastening accessory which is typically used in heavy-load attachment and high-pressure installation with an intimate function of structural integrity, load spreading, and bolt-hole protection. At the same time, unlike the common round washers, square shape would have a larger area on the surface, which enables its use on base plates, anchor bolt setups, timber connections, as well as concrete embedded fasteners.

Manufactured from the best premium SS 304 or SS 316 stainless steel, this stainless steel square washer will easily resist corrosion, rust, moisture, and chemical exposure due to the highly marine and outdoor as well as industrial exposure. Run-of-the-mill square washers serve primarily in civil infrastructure, steel fabrication, and industrial plant installations in the UAE and GCC.


✅ Key Features:

  1. Square Shape for Maximum Load Support
    Designed to provide a wider bearing surface, ensuring that bolts don’t pull through softer or oversized holes in base plates, concrete, or wood.

  2. Premium Stainless Steel Material
    Available in SS 304 and SS 316 for unmatched corrosion resistance and durability.

  3. Ideal for Anchor Bolt Assemblies
    Perfect for use with foundation bolts, threaded rods, and structural fasteners in base mounting systems.

  4. Strong Non-Deforming Design
    Maintains washer shape and surface flat under extreme bolt torque and pressure loads.

  5. Weatherproof & Long-Lasting
    Zero maintenance needed — performs over years in outdoor, coastal, and industrial conditions.
