Plain Finish 9/16" 3/8" Hexagon Top Lock Nut ASTM Gr2 Prevailing
Prevailing torque nuts, are also called hex top lock nuts, offer
various kinds of locking features to meet customer's performance
requirements. Consistent torque at tension allows for reliable
The top lock nuts are manufactured from low-carbon steel to meet
Grade A performance specifications. These kinds of prevailing
torque lock nuts are designed for use in non-critical applications
with Grade 2 or Grade 5 hex bolts, or other customized bolts.

There are many kinds of lock nut. Prevailing Torque Type Hexagon Top Lock Nut.
The first is on the outer surface of the nut to the inner
circumferential surface of the threaded screw holes drilled
therethrough (typically two, distributed in the outer-section 90)
for screwing the small-diameter countersunk screws, the purpose is
to thread applying a radial direction of force to prevent the lock
nut loosened. At present quality on the market in a better lock nut
inner peripheral surface of the nut encrusted consistent with the
lock nut threaded brass pieces, to avoid radial top screws directly
contacts the locking threads and damaged By. This rotational
movement of the locking nut locking shaft-type parts of the case
gradually began to use, such as a ball screw mounting end bearing
The second lock nut is composed of two parts, each part has
staggered cam, wedge design due to internal slope angle oblique
angle is larger than the nut bolts, this combination will firmly
bite into one whole, when vibration occurs when, DISC-lOCK locknut
raised portions mutually dislocation, resulting in uplift tension
to achieve the perfect anti-loosening effect.
Lock nut is widely used in machinery and other industries.
