High-Strength Steel Nylon-Insert Locknuts—Grade 8
A nylon insert grips the bolt to resist loosening without damaging threads. These nuts are reusable, but their holding power lessens with each use. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.
Zinc yellow-chromate plated steel locknuts resist corrosion in wet environments.

Low-Strength Steel Locknuts for use with Cotter Pins
Secure these hex slotted nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. They’re not recommended for use on parts exposed to high vibration because the pin is prone to shearing under prolonged stress. Height includes the slots. Cotter pins are not included. A zinc plating provides corrosion resistance in wet environments.
