Left-Hand Threaded Low-Strength Steel Thin Hex Nuts
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Also known as jam nuts, they are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels.
Black-oxide steel nuts have a dark surface color and are mildly corrosion resistant in dry environments.

Medium-Strength Steel Locknuts for use with Cotter Pins—Grade 5
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. They're zinc plated to resist corrosion in wet environments.
