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. They also meet DIN dimensional standards.

Left-Hand Threaded 18-8 Stainless Steel Thin Hex Nuts
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They have good chemical resistance and may be mildly magnetic. 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.

Left-Hand Threaded Super-Corrosion-Resistant
316 Stainless Steel Thin Hex Nuts
Made of 316 stainless steel for excellent corrosion resistance—including in salt water—these nuts tighten to the left and won’t loosen from counterclockwise motion. For use in low-clearance areas, they’re half the height of standard hex nuts. They can also be jammed against another nut to hold it in place. When used with a standard hex nut, they’re good for fastening most equipment.

Left-Hand Threaded Brass Thin Hex Nuts
These nuts tighten to the left and won’t loosen from counterclockwise motion. Made from brass, they resist corrosion, conduct electricity, and are nonmagnetic. They’re half the height of standard hex nuts, so they’re good for use in low-clearance areas. Jam them against another nut to hold them in place. When used with a standard hex nut, they’re suitable for fastening most equipment.

Low-Strength Steel Thin Nylon-Insert Locknuts
These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.
Zinc-plated steel locknuts resist corrosion in wet environments.

18-8 Stainless Steel Flanged Knurled-Head Thumb Nuts
These thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.
