Square Washer – 316 Stainless Steel | Heavy-Duty Load Distribution for Structural & Marine Applications

These 316 stainless steel square washers are designed to distribute loads over a larger surface area than standard round washers, making them ideal for structural, marine and heavy-duty fastening applications.

Manufactured from marine-grade 316 stainless steel, they provide excellent corrosion resistance in coastal, marine and harsh outdoor environments. Square washers are commonly used in construction, timber connections, structural steelwork, retaining walls, fencing and engineering projects where increased bearing surface is required.
