What is the tolerance range of precision screws?
Nuts are usually used in conjunction with bolts or screws to fasten other components and are a common and widely used component. In order to make the nut not easy to loosen and fall off when it is subjected to strong vibration and irregular strong toggling, the combined nut has appeared on the market.
In order to solve the problems existing in the prior art, Yueluo Company provides a fastener that prevents the nut from falling off. After the nut is installed in place, a locking strip can be inserted into the groove of the bolt to lock the nut, so that the nut can be locked. It cannot be loosened to prevent the nut from falling off. If the nut needs to be removed, the nut can be removed normally after removing the locking strip.
Many existing products need to use screws in the production process, especially in the field of nuclear power sluice gates, it is necessary to fill a part of the sluice gate with screws to fix the size and structure. If the fixing effect is not good, then It will lead to more leakage of water gates, waste a lot of water resources, and even cause safety accidents.
Friction type high-strength bolts: suitable for beam and column connections of steel frame structures, solid web beam connections, heavy-duty crane beam connections in industrial plants, braking systems and important structures bearing dynamic loads. Pressure-bearing high-strength bolts: Can be used for shear connections in statically loaded structures that allow a small amount of sliding or in members that are indirectly loaded with dynamic loads. Tensile high-strength bolts: When the bolts are in tension, the fatigue strength is low. Under the action of dynamic load, its bearing capacity is not easy to exceed 0.6P (P is the allowable axial force of the bolt). Therefore, it is only suitable for use under static load. Such as flange butt joints, T-joints, etc. of pressure members.
