Next: Flanged Stover Nut (DIN 6927) 
Prev: Slotted Nuts 
The Stover Nut is a hex all-metal prevailing torque self-locking nut, made to DIN 980V standard.
These locknuts are vibration resistant self-locking nuts, which are resistant to shocks, vibration and dynamic loads – and they can be reused a number of times.
The locking function is achieved by the deformation of part of the nut. The nut will run smoothly until it reaches the deformed part, after which the clamping force will increase.
The Stover Nut is typically manufactured as standard in Steel Grades 8, 10 and 12.
Available from Fastenright as standard in metric sizes ranging from M4 onwards, with various finishes and pitches available to order.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
