Service HotlineThe composition and proportion of this high-performance stainless steel screw thread are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%- 0.03% S; 12%-14% Cr; 0.8%-1.5% Mo and the rest is Fe. The preparation method includes the following steps: smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain a stainless steel plate blank; coating and drying; cold drawing; cleaning and drying with a neutral activator; quenching; tempering ; coated and dried; drawn into stainless steel thread. This high-performance stainless steel screw line is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low.
GB6177 Hexagon Flange Nuts - Grade GB55 Hexagon Thick Nuts GB56 Hexagon Extra Thick Nuts GB1229 Large Hexagon Nuts (High Strength for Steel Structure) Lock Nuts Other Names: Root Nuts, Lock Nuts, and Nuts. Purpose: To lock the outer joint of the through wire or other pipe fittings. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 46 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
At present, the commonly used locking structure is a split pin (hereinafter referred to as a cotter pin type adjustment nut) or knocking the sheet on the adjustment nut into the steering knuckle groove (hereinafter referred to as a sheet type adjustment nut), these two structures are mainly used in single row Bearings are barely used in bearing units and hub bearing units. The former has a complicated structure and the cotter pin is easy to fall off; the latter requires workers to control the press-in force. Too much pressure can easily lead to the cracking of the sheet structure on the adjusting nut, and too little pressure can easily make the adjusting nut failure, and is impacted in the axial direction.
Therefore, how to provide a socket nut, a fastener and an installation method thereof that are more firmly connected and can be applied to thin-walled profiles is a technical problem to be solved by those skilled in the art.
