Bearing Spring Lock Washers for Slotted Bearing Nuts
 |  |
For Chamfered Nuts |
Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening.
Steel—Steel washers are strong and flexible.
Stainless Steel—Stainless steel washers are more corrosion and chemical resistant than steel washers.
External Tooth—Washers with external teeth grip components using their teeth, in addition to spring tension.

Wave Spring Lock Washers
 |
The wavy shape flexes like a spring to keep nuts and screws secure on slightly uneven surfaces. These washers add a small amount of tension to stop fasteners from backing out due to mild vibration. While they don't hold as well as other lock washers, they do grip slightly better than curved washers. They work best in electrical panels, light fixtures, and other light duty assemblies. Since these washers hold their shape when untightened, you can reuse them a handful of times without losing strength.
18-8 Stainless Steel—The choice for wet and outdoor environments, these washers won't rust when exposed to moisture. However, they can't hold up to the harsh chemicals that 316 stainless steel can.
3 Wave—More points of contact than single-wave washers for a better grip.
