Often referred to as reversible locknuts, these thread on from both sides, eliminating the possibility of improper fastening and screw damage. Unlike nylon-insert locknuts, the middle threads' uneven form provides a firmer grip on the screw. The threads make installation and removal more difficult, but they also keep the nut from backing out from vibration. You might require specialized equipment, such an impact wrench or propane torch, to remove these nuts. Nuts cannot be reused.
These locknuts are almost half as robust as medium-strength steel nuts and are rated Grade 2, Class 6, or lower. In order to prevent thread stripping during installation, use them with screws that have a comparable strength grade.
These locknuts, which are rated Class 10, Grade 8, or C, are around 25% stronger than medium-strength steel nuts. Make sure your screw has a similar strength rating to prevent stripped threads during installation.
The majority of machinery and equipment can be fastened with these Grade 5 or Class 8 nuts. Make sure your screw has a similar strength rating to prevent stripped threads during installation.
These rust-resistant locknuts are ideal for outdoor and damp settings.
