With an increased O.D., thickness and bearing area, this split washer is ideal for heavier duty applications involving the application of higher tightening torques. The Heavy Section helical spring lock washer contributes significantly to the maintenance of tightness or tension in applications involving screws, bolts and nuts under high loads. Our lockwashers are made in the USA. They meet all ASME standards in addition to RoHS and DFARS compliance when required.
We also have Mil-Spec Heavy Helical Spring Split Lockwashers.
