A flat washer is a fastening product that has the appearance of a flat disk with a smooth cylindrical hole in the middle, the diameter of which is slightly larger than the diameter of the metric product with which it is used. The main feature of the puck is that it has 4 types: Z, M, L, LL, each of which differs in the width of the puck field, in the increasing direction, respectively, but the thickness of the puck does not change.
Scope NFE 25-514-Z is used on structures made of light and soft materials, where a large clamping area is required at the connection point, but at the same time there is a need for a lighter weight washer and, accordingly, lower costs per attachment point .
Material stainless steel. The A4 steel grade allows you to use fasteners with significant temperature changes and in an aggressive and humid environment.
No coverage.
