What is the tolerance range of precision screws?
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a low-carbon steel rivet nut fastener, which can be easily fixed on a thin wall without welding, easy to operate, firm riveted, and suitable for single-sided riveting.
Standard parts are commonly used parts, which are widely used in various mechanical structures. Among them, the T-track bolt is a common standard part. The existing T-shaped track bolts, especially those used in high-speed railways, are often installed in pre-buried tracks, and the T-shaped track bolts are not easy to install, which may easily cause positional deviation.
Nuts on the market still have certain defects. The bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked. The bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards and has a protective effect. Bad problem, for this, we propose a nut with self-locking function
The locking effect of the spring washer is general, and the important parts are used as little or not as possible, and the self-locking structure is adopted. For spring washers used for high-speed tightening (pneumatic or electric), it is best to use surface phosphating washers to improve their anti-wear performance, otherwise it is easy to burn out or open mouth due to friction and heat, and even damage the surface of the connected parts. For thin plate joints, spring washer construction should not be used. According to statistics, spring washers are used less and less in automobiles.
