Form G flat washer (also known as a mudguard washer or penny washer), manufactured in accordance with DIN 9021 and NF E25-513 standards, is crafted from durable steel with a zinc-plated finish for corrosion resistance. With a hardness class of 140 HV for sizes over M16 (and 100HV for smaller sizes) for robust strength and reliability. Designed for larger-than-normal outer diameters, it is ideal for distributing load and reducing pressure on surfaces, perfect for use in environments requiring extra protection, like automotive mudguards. The washer's design ensures compatibility with a wide range of applications, making it a versatile choice. Supplied in a large pack.
