Brass Thin Hex Nuts
These nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. 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.

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.
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 While no longer active, DIN 936 is still a commonly referenced standard for material and dimensional compatibility.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.

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.
