316 Stainless Steel Thin Hex Nuts
With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance. Sometimes called jam nuts, you can also jam them against standard nuts to hold them in place when fastening machines and equipment.

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 8 steel, these nuts are suitable for fastening most machinery and equipment.
