Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. Commonly used as locknuts, threading a thin nut against any other hex nut prevents loosening caused by vibration. You can also use them as jam nuts by threading two of these thin nuts against each other on a threaded rod to create a gripping point for turning the rod without damaging its threads. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.
ISO 4035 nuts are functionally the same as DIN 439B nuts (sometimes called DIN 439-2), but have slightly different width tolerances. These nuts have chamfered edges that make them less sharp than DIN 936 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 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.

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic. The head is knurled for slip-resistant controlled adjustment and the collar raises the head to make it easy to grip.
Black-oxide stainless steel nuts have a dark surface color.

Made from 18-8 stainless steel, 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.
Passivated stainless steel nuts provide added protection against oxidation and corrosion.

About half the strength and two-thirds the height of medium-strength steel square nuts, use these metric nuts in light duty, low-clearance applications. Also known as square jam nuts, they’re commonly jammed together to hold each other in place. Their flat, broad sides make them easy to grip with a wrench and keep them from rotating in channels and square holes. Compared to hex nuts, a greater area is in contact with the fastened surface. A zinc plating protects these nuts from corrosion in wet environments.
These nuts meet DIN 562, an international standard that signifies their material and dimensions are compatible with other products and tools.
