These Form C stainless steel washers provide a premium-grade fastening solution for demanding applications where reliability, precision, and long service life are essential. Engineered from corrosion-resistant A4 (316) stainless steel, they deliver outstanding durability and strength, making them ideal for use in industrial, marine, construction, and engineering environments where exposure to moisture, chemicals, or harsh weather is common.

Manufactured to meet recognised standards such as DIN 125 and BS 4320, these washers are designed for accurate fitment, consistent performance, and secure load distribution under bolted connections. Their precise dimensions help prevent damage to mating surfaces, reduce the risk of loosening under vibration, and improve the overall integrity of the fastening assembly.

The high-grade 316 stainless steel construction offers excellent resistance to corrosion, including in coastal, offshore, and chemically aggressive settings, helping to ensure a long-lasting, maintenance‑friendly solution. Suitable for use with matching stainless steel bolts, nuts, and threaded components, these washers support a wide range of mechanical, structural, and fabrication projects.

Available across a selection of common metric sizes, this range allows you to choose the right washer for everything from light-duty assemblies to heavy-duty structural connections. Whether used in machinery, fixings, frameworks, or marine hardware, these Form C washers provide a robust, high-performance fastening component that maintains its integrity in even the most demanding conditions.
