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.

Steel Hex Panel Nuts

Fasten these panel nuts with a wrench for more torque while tightening than knurled panel nuts. Also known as dress nuts, they're extremely thin for use in tight spaces such as electrical panels.
