Medium-Strength Steel Hex Nuts—Grade 5
These nuts are suitable for fastening most machinery and equipment.
Zinc-plated steel nuts resist corrosion in wet environments.
For technical drawings and 3-D models, click on a part number.
High-Strength Steel Hex Nuts—Grade 8
These nuts are about 25% stronger than medium-strength steel nuts.
Zinc yellow-chromate plated steel nuts resist corrosion in wet environments.
Zinc-aluminum coated steel nuts are more corrosion resistant in wet environments than zinc-plated steel nuts. They're also known as ultra coat and armor coat nuts.
Black-Oxide steel nuts have a dark surface color and are mildly corrosion resistant in dry environments.

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.

Left-Hand Threaded Medium-Strength
Steel Thin Hex Nuts
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. 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. 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.

High-Strength Steel Nylon-Insert Locknuts—Grade 8
A nylon insert grips the bolt to resist loosening without damaging threads. These nuts are reusable, but their holding power lessens with each use. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.
Steel locknuts without a finish are ready to be painted or finished.
Black-oxide steel locknuts have a dark surface color and are mildly corrosion resistant in dry environments.
Zinc yellow-chromate plated steel locknuts resist corrosion in wet environments.

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.

Low-Strength Steel Locknuts for use with Cotter Pins
Secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. They're also known as castle nuts and slotted nuts. They’re not recommended for use on parts exposed to high vibration because the pin is prone to shearing under prolonged stress. Height includes the slots. Cotter pins are not included. A zinc plating provides corrosion resistance in wet environments.

Steel-Insert Locknuts for Extreme Vibration—Grade 5
When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut’s load to resist spinoff caused by vibration. These locknuts are often used in shakers and vibrating equipment. The strength of the bolt should match the strength of the nut to prevent damaging threads. Made from Grade 5 steel, they're suitable for fastening most machinery and equipment.
