Description

This is the "Special size flat washers" series developed to a standard that allows you to select a wide range of outer diameters and thicknesses compared to conventional flat washers. The screw head can be stabilized when the diameter of the other material is larger than the screws. The screw head seat is wider for better adhesion to the other material. Sometimes called washers, flat washers, etc. RoHS 2 compliant.
