Low-Strength Steel Hex Nuts
About half the strength of medium-strength steel nuts, these nuts are for light duty fastening applications, such as securing access panels.

Medium-Strength Steel Thin Hex Nuts—Grade 5
Also known as jam nuts, these 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.

Low-Strength Steel Thin Hex Nuts
Also known as jam nuts, these 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. Some of these screws meet ISO and DIN dimensional standards.
Nuts with fine and extra-fine thread spacing are less likely to loosen from vibration than nuts with coarse thread spacing.

High-Strength Steel Extra-Wide Thin Nylon-Insert Locknuts
About half the height and 10% wider than standard nylon-insert locknuts, use these in low-clearance applications or jam one against an extra-wide hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than low-strength steel extra-wide thin locknuts.
Black-phosphate steel locknuts resist corrosion in wet environments.
