SS 316 Big OD Washers – Oversized Stainless Steel Washers for Load Due to Their High Capacity and Corrosive Environments

SS 316 Big OD Washer is a heavy-duty washer that can be used to distribute a very large load over a wide area, typically associated with high-strength bolting systems, marine installations, or industrial machines in conditions that are very corrosive, very humid, or extreme.

Manufactured from superior quality AISI 316 stainless steel, oversized flat washers also make it impervious to rust, saltwater, and harsh chemicals. The large outer diameter or OD maximizes the surface coverage, thus spreading pressure and preventing pull-through for soft metals, wood, and plastic, or large bolt holes.

To make sure that any project in UAE continues to get long-term merit over intensive pressure, those great marine contractors, oil & gas projects, desalination plants, HVAC installers, and structural engineering firms trust these washers.

✅ Key Features:

Marine-Grade SS 316 Material
Offers outstanding corrosion resistance against chlorides, seawater, chemicals, and acidic environments—ideal for offshore, coastal, and industrial zones.
Big Outer Diameter for Maximum Load Distribution
Prevents deformation or surface damage by spreading bolt force over a wider area—perfect for structural joints and soft surfaces.
High Tensile Strength
Withstands high bolt torque and extreme vibration without cracking, warping, or loosening.
Rust-Proof & Maintenance-Free
Suitable for outdoor, subsea, and chemical plant applications where other metals would fail.
Smooth Finish & Precise Machining
Ensures clean fit with studs, anchor bolts, threaded rods, and hex bolts.
