FEATURES

DIN 128 A Curved Spring Lock Washers are split bowed spring washers that are said to be more resistant to vibration than split helical spring washers and prevent thrust-induced loosening by maintaining a sufficiently high preload. Since their design is non-helical, they can be used with both right- and left-hand bolted joints. Zinc plated and plain finish (unplated and can rust) spring steel and stainless steel can be supplied. Washer size, which is its nominal hole size, should be matched to the screw size—select an M8 washer if you have an M8 screw. DIN 128 A is recommended for new designs in place of DIN 127 A, DIN 127 B and DIN 128 B.
