All Metal Self Locking Flange Nut

This All Metal Self Locking Flange Nut is a one-piece hex locknut with the addition of an integrated disc spring washer. The locking feature is achieved by the two de-pitched self locking slots found on the turret section.

Once installed, the slotted turret section reverts to its original form and each slot grips the shank – or thread – of the bolt on two different planes and opposite sides.

The flange provides a larger surface area which helps to distribute pressure across the mating surface. It also enables use with oversized or irregular shaped holes and removes the need for an external washer. Turret Type All Metal Self Locking Nuts are also available at Fastenright.

These reusable components host a high resistance to temperature and can be used in volatile environments with temperatures ranging between -200°C and 400°C, depending on the material and finish.

Manufactured from 304 / A2 Stainless Steel, 316 / A4 Stainless Steel, and Steel grades 8 & 10. All Metal Self Locking Flange Nuts can also be supplied in non-standard materials such as Brass, Bronze, and Titanium.
