What is Threaded Locking Nuts?

Type F or threaded locknuts are commonly used in machinery, equipment, automobiles, furniture, and other fields. It has an internal taper to strengthen the tightening force with the threads and can avoid thread sliding or loosening. F-type lock nut locking mode for the thread half-angle 30 ° angle three-point locking, its locking design, can make the fixed copper threads fit in the male threads, so that the relaxation effect, because of its 30 ° Angle of the design, to reduce the lock screws generated by the force-distance.

F-type lock nut, its locking copper bolt, and the thread is 30 ° in design, so it does not bear the axial load on the thread. When the nut-locking copper pins are locked, the thread surface will not release the axial load; the nut will not be deformed. The three equally spaced locking pins can also correct deviations in the components assembled to the shaft. Since the locking pins are not bent, the F-type locknuts maintain their original accuracy even after repeated loading and unloading. The three equally spaced locking brasses can adjust the deviation of other parts mounted on the shaft. Since the locking brass will not be deformed, the F-type nut will maintain its precision even after many disassemblies.

R-type and F-type. These two types of nuts, bearings, and other components can be reliably axially positioned on the shaft, and precision is ensured. Their unique feature is the phosphor-bronze locking pins evenly distributed along the circumference. These pins are pressed against the shaft threads using hexagon socket head cap screws, preventing the nut from turning. Installation and design are simple. No additional lock washers or slots in the shaft are required. The locking pin and flat head screw make the same Angle to the shaft as the threaded face. The end of the locking pin is processed in the same process as the threads and thus also has a threaded bud type, and the nut is tightened in place entirely by friction between the locking pin and the shaft threads and by adhesive friction between the threaded surfaces.

When installing spindles, ball screws, or bearings, the double round nuts are usually used due to the large amount of thread and plane deflection, resulting in shaft deformation, which makes it challenging to meet the requirements of the designers in terms of mechanical accuracy and service life. Juxin Fasteners has developed a series of precision locknuts with threads and faces clamped in a single operation while being fine-turned or ground, which can effectively prevent shaft deformation in the installation and are matched with various locking forms. With various locking forms, it is easy for you to install locking and easy to dismantle, which fully meets the designers' design requirements. Juxin Fasteners develops and produces five series of precision locknuts and precision balanced locknuts, such as web locknuts, radial locknuts, retracted locknuts, axial locknuts, compression locknuts, and so on, based on the advanced mechanical design and manufacturing technology, and is specialized in the research and development, production and promotion of precision locknuts, as well as the continuous innovation and growth.

Left and right-hand rotation of web lock nuts

There are two types of tooth-bellied locknuts: left-handed and right-handed. A left-handed nut rotates to the left when manually turned clockwise, while a right-handed nut rotates to the right when manually turned counterclockwise.

Characteristics of tooth belly locking nut

1. Simple structure: the tooth belly lock nut is mainly composed of a hexagonal nut and a metal sleeve with trapezoidal teeth; the structure is simple, straightforward, and easy to install.

2. Easy to install: The tooth belly lock nut only needs a hexagonal wrench to complete the installation, which is an obvious advantage compared with other nuts.

3. Long service life: Because the metal sleeve of the tooth-belly lock nut will tightly clamp the nut after extrusion, the anti-loosening effect is excellent, and it is not easy to loosen in the process of use, and has a long service life.

4. Good anti-loosening effect: The tooth web lock nut's extrusion locking technology prevents the nut from loosening under the equipment's vibration to ensure its safety.

5. High tensile strength: Because the strength of the extruded metal sleeve is better than that of the standard nut, the tensile strength of the tooth web lock nut is much higher than that of the standard nut.

Notes on the use of left-handed and right-handed nuts

1. left-hand nuts are used less frequently in the mechanical field, while right-hand nuts are the most common type.

2. Select the appropriate thread size and the corresponding type of lock nut.

3. The locking force should be moderate to avoid overtightening, which may damage the equipment, or loosening, which may bring safety hazards.

4. Left-handed and right-handed nuts should not be used together, which may damage the threads or cause poor fastening.

5. It should be noted that in the process of use if you find that the mane and tail of the locking nut are cracked or have obvious deformation, they should be replaced immediately.

Application of Tooth and Belly Locking Nuts

Tooth and web lock nuts are usually used in machinery and equipment, industrial equipment, automobiles, aviation and ships, and other high-strength occasions, such as aircraft engines, high-speed railways, automobile chassis, and other applications, which can effectively ensure the safety of the equipment. The tooth and belly lock nut has two left-hand and right-hand rotation types and has been a standard fastener in recent years. When used, the appropriate specifications and types should be selected, the locking strength should be moderate, and attention should be paid to not mixing the left-hand and right-hand nuts. Only the correct use of the nut plays its maximum fastening function.
