Metric Brass Thin Hex Nuts![]() ![]() Made from brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength. Also known as jam nuts, they help prevent loosening from vibration when tightened in pairs. Two nuts jammed together also function as a gripping point on a threaded rod, so you can turn the rod without damaging the threads. Nickel-plated brass nuts have excellent resistance to chemicals and salt water. DIN 936 nuts are a little taller than DIN 439B nuts, and sometimes slightly wider. While no longer active, DIN 936 is still a commonly referenced standard for material and dimensional compatibility. DIN 439B nuts are chamfered, so their edges are less sharp than DIN 936 nuts. DIN 439B was replaced by ISO 4035 but remains a common reference point. The ISO standard has slightly different tolerances for width.

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 Although no longer active, this standard is often referenced for compatibility.

Brass Extra-Wide Thin Hex Nuts![]() ![]() Brass nuts are resistant to corrosion in wet environments, electrically conductive, and nonmagnetic. Also known as heavy jam nuts, they are about half the height and 10% wider than standard hex nuts. Use them in low-clearance applications or jam one against another extra-wide hex nut to hold it in place.
| Brass Hex Panel Nuts![]() These panel nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They can be fastened 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. Nickel-plated brass panel nuts have excellent resistance to chemicals and salt water.
