They are used in threaded assemblies for distribution of load on a greater surface. They are also used for oversized or oblong holes and for protection of assembled parts. This family includes a complete range of products: some of them have been designed to be used separately, others have been designed to be assembled on a nut or a screw. ‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒‒ Categories: Flat washers, Our Products, Washers Additional information Part print Contact Form Additional information External diameter tolerance + / -0.25 Ø External [d2] (mm) 30.00 Ø Internal [d1] (mm) 7.45 Internal diameter tolerance +0, 15 Material C45E Maximum hardness [HV] 300 Minimum hardness [HV] 200 Screw diameter M 8 Thickness [e] (mm) 3.00 Thickness tolerance ±0, 11 Heat treatment No Part print Contact FormLast name *First name *Company *Email *PhoneMessage *0 / 180 Send the message Related products 935946 450509 936825 450803
