Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 and Class 04 steel, these nuts can be used for fastening panels and other light duty fastening applications.

Use these nuts for light duty fastening applications, such as securing access panels.

With a shorter hex height than standard DIN 985 locknuts, these nylon-insert locknuts meet international ISO 10511 dimensional standards and are easy to install in tight spaces.

These Grade 8 locknuts are about 25% stronger than medium-strength steel thin locknuts.

Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.

Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments.

About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.

These panel nuts are knurled to provide a secure grip for tightening and loosening by hand.
