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.

18-8 Stainless Steel Thin Nylon-Insert Locknuts
These locknuts have good chemical resistance and may be mildly magnetic. They're about half the height of standard nylon-insert locknuts. Use them in low-clearance applications or jam one against a 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.

Thin Steel-Insert Locknuts for Extreme Vibration
About two-thirds the height of standard steel-insert locknuts, use these in low-clearance applications or jam one against a hex nut to hold it in place. 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. They're 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, these nuts are suitable for fastening most machinery and equipment.
