Metric DIN 125a A4 (316) Stainless Steel Flat Washer

Metric DIN 125A A4 (316) Stainless Steel Flat Washers for Extreme Environments

When corrosion resistance is non-negotiable, the Metric DIN 125A A4 (316) Stainless Steel Flat Washer delivers unmatched performance. Manufactured to DIN 125A dimensional standards, this metric flat washer ensures precise fit, consistent tolerances, and dependable load distribution in critical fastening assemblies. Designed for harsh and corrosive environments, it is the preferred solution for marine, coastal, chemical processing, and industrial applications.

A4 (316) Stainless Steel – Superior Corrosion Protection

Enhanced Resistance with Molybdenum

A4 stainless steel, commonly known as 316 stainless steel, contains molybdenum for enhanced resistance to chlorides, saltwater, and aggressive chemicals. Compared to A2 (304) stainless steel, A4 washers offer significantly greater protection against pitting and crevice corrosion, making them ideal for high-humidity and chemical-exposed settings.

Built for Long-Term Durability

The smooth, flat profile of the DIN 125A washer evenly distributes clamping force under bolt heads and nuts, preventing material deformation and reducing the risk of pull-through. This improves joint integrity and extends the service life of both fasteners and connected components.

Precision Metric Performance Across Industries

DIN 125A A4 flat washers are engineered for use with standard metric bolts, screws, and threaded rods. Their tight dimensional tolerances ensure accurate bolt seating and optimal clamping force in structural, mechanical, and fabrication applications.

Common uses include:

• Marine vessels and offshore structures

• Chemical processing equipment

• Food-grade and sanitary installations

• Outdoor construction and coastal infrastructure

• Industrial machinery and fabrication

Key benefits include:
