Plain Finish Zinc Plated Carbon Steel Gr4 Gr8 Gr2 G5 1/4"-2" M4-M24 Three Point Hex Head Lock Nut
Description:
The first is to use two same nuts on the bolt, attaching nuts a tightening torque between two, so that the bolt connection is reliable.
The second is dedicated locknut, and need a way to lock washer together. Dedicated locknut not hex nuts, but in a round nut, the nut circumference opened a three, four, six or eight notch (depending on the nut size and manufacturer product line varies), which tighten the focus of both a few notches tight tool, but also snaps into place lockwashers bayonet.
The third 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 locking.
The fourth 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.
The fifth is locking structure, designed by improvements on the threaded structure, without the help of other external
