FLAT WASHERS STAINLESS STEEL 316 PACK

Flat washers are primarily used to distribute the clamping load of a bolt or nut over a larger surface area. Using Grade 316 stainless steel (marine grade) specifically provides the added benefit of extreme corrosion resistance in harsh environments.

Primary Mechanical Functions
Load Distribution: They prevent the fastener head or nut from digging into or "sinking" into softer materials like wood, aluminium, or plastic.
Surface Protection: They act as a barrier to protect the finish of the material being fastened from being marred or scratched by the rotation of the bolt or nut during tightening.
Gap Bridging: They can cover oversized or slightly misaligned holes, ensuring the fastener has a solid bearing surface to clamp against.
Spacers: They are often used as shims to fill excess space if a bolt is slightly too long for the application.

Why Choose Grade 316?
Grade 316 contains molybdenum, which makes it significantly more resistant to pitting and crevice corrosion than standard 304 stainless steel. This makes 316 washers essential for: 
Marine Environments: Boat deck fittings, docks, and coastal structures exposed to salt spray or submersion.
Chemical Processing: Equipment in pharmaceutical or petrochemical plants that handle aggressive acids or chlorides.
Food & Beverage: High-hygiene environments like commercial kitchens and processing plants, as 316 is non-reactive and easy to sanitise.
Outdoor Construction: Long-lasting architectural projects, fencing, and pool areas where rust streaks must be avoided.
