Stainless Steel Distorted-Thread Flange Locknuts

These flange locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread that grips the bolt for a stronger hold than nylon-insert flange locknuts. A flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. These nuts may be mildly magnetic. Height includes the flange.
A286 stainless steel nuts cannot be reused.
