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.
ISO 4035 nuts are functionally the same as DIN 439 nuts but have slightly different width tolerances. This ISO spec replaces the DIN spec, however DIN 439 is still a common reference point. These nuts have chamfered edges.

Left-Hand Threaded Super-Corrosion-Resistant 316 Stainless Steel Thin Hex Nuts
With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance. Sometimes called jam nuts, you can also jam them against standard nuts to hold them in place when fastening machines and equipment.
All metric nuts meet DIN standards and some also meet ISO standards, which means they adhere to strict dimensional and material requirements. While DIN is no longer active, it's often referenced for compatibility.

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.
ISO 4035 (formerly DIN 439B) nuts are chamfered, so their edges are less sharp than DIN 936 nuts. This new ISO standard is functionally the same as the DIN standard it replaced, with slightly different tolerances for width.

Left-Hand Threaded Medium-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. They're suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut. A zinc plating provides corrosion resistance in wet environments.

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.
Nuts that meet DIN 439B comply with international standards for dimensions and materials. Although no longer active, this standard is often referenced for compatibility.
