CONIC SEAT WASHER D6319D 20MM (23*36) A4

Quantity:

A conical seat washer is a specially shaped washer with an angled or tapered bearing surface designed to match the profile of a conical seat fastener. Its purpose is to ensure full, even contact between the bolt head or nut and the surface being clamped, especially when components are curved, angled, or require improved alignment. This washer helps distribute load more effectively and reduces the risk of fastener loosening caused by uneven seating.
