What are Zinc Form A washers used for?

Zinc Form A washers are used to spread load under a bolt or nut, prevent surface damage and improve clamping performance in internal applications.

Manufactured to DIN 125-A, these washers feature a traditional flat Form A profile and are plated in Clear Cr3 Trivalent Zinc (3–5 microns). They are suitable for clean, dry and low humidity environments.
