Form B Flat Washers A4 Stainless Steel

Product Description

A4 Stainless Steel Flat Washers – Form B to DIN 125B

Form B Flat Washers are precision-manufactured from A4 (316) grade stainless steel, offering high corrosion resistance and reliability in demanding environments. These washers conform to DIN 125B standards and are distinguished from Form A washers by their thinner profile, making them ideal where space constraints or reduced thickness are required without compromising surface protection or load distribution.

A4 stainless steel is commonly used in marine, chemical, food, and outdoor applications due to its superior resistance to corrosion, including saltwater and harsh weather exposure. The washers offer a smooth bearing surface to prevent surface damage during fastener installation, reduce pull-through, and evenly distribute clamping force over larger areas.

Suitable for use with stainless bolts, screws, and nuts, these Form B washers are available in a full range of metric sizes to match M4 to M30 fasteners. Their thinner design makes them particularly useful in assemblies where minimal washer thickness is critical.
