Spring Lock Washers for Slotted Bearing 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 washers are strong and flexible.
Stainless steel washers are more corrosion and chemical resistant than steel washers.

Oversized Split Lock Washers
Compared to standard split lock washers, these are thicker and have larger outside diameters. As the screw is tightened, these washers flatten to add tension to the joint. They counteract fatigue around the joint caused by small amounts of vibration, making them a popular choice for preventing fasteners from loosening. However, they resist the least amount of vibration compared to other locking washers.
These washers match with fasteners that have right-hand threads to prevent clockwise rotation. The uneven split ends bite into fasteners for a tight grip but won’t work with hardened surfaces. They hold better than curved or wave washers. They’re not reusable after tightening.
All washers adhere to strict ASME dimensional standards.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
